TITLE: Calcium chloride as the best chemical aigent for insuring smooth supply of
powdered substances during winter
SOMICE: Hutnicke listy, no. 2, 1966, 127-128
TOPIC TAGS: steel industry, Iron, calcium chloride
ABSTRACT: For cres with a water content of 4-5% 1 to 2 kg of CaC12 are required
per ton of ore for temperatures up to - 15*C; below thig level 2 to 5 kg are needed.
The chloride is added in the form of an anhydrous powler. Experience obtained in
shipping iron ore with this additive in Poland, Yugoslavia and Rumania is described.
It is important to prevent contact between the chloride and snow. Experience in
Czechoslovakia during the winter of 1964/65 was very favorable. Orig. art. has:

The structure of the cerebellar arteries shows definite characteristics arcording
to age. such that in adults. as distinct from children.the re is observed a greater
tortuosity of the vessels in the shape of arcs and loops formed by the stems of the
cerebellar arteries in the various parts of the cerebellum. Where there is a
strong development of the anterior inferior cerebellar artery and a high origin of
the posterior Inferior cerebellar artery, the stems of the two arteries form extens-
ive area tytng within the limits of the ponto-cerebellar angle. The wide arc tra-
versing the antero-infortor surface of the pons, the middle cerebellar peduncle. the
flocculus, the biventral lobule and the tonsil, In very often formed by the anterior
inferior artery and less frequently by the posterior inferior artery. Usually one
arterial stem in distributed to the antero-inferior surface of the Pons, but two may
be found; in the latter case, the stems of the anterior inferior and posterior Infer-
lor arteries, or the stems of the anterior interior and medial inferior cerebellar
arteries, are men, frequently distributed to the area mentioned. In the region of
the middle cerebellar peduncle the stems of the cerebellar arteries are distributed
in the same order an on the antero-inforior surface of the pons. In the region of
theanterlor quadrate lobule (on its anterior surface) a strongly developed external
branch of the superior cerebellar artery can most frequently be observed. more
rarely (in 20% of cases) the stem of the anterior inferior cerebellar artery. some-
times together with a strongly developed branch of the superior cerebellar artery.
In the region of the flocculus one arterial stem In most commonly met with. Where
two arterial stems are distributed within the boundaries of the flocculus, they most
frequently belong to the anterior Interior and posterior interior and less commoni
to the anterior Inferior and medial Inferior cerebellar arteries. The topography or
the arteries lying in the region of the flocculus in similar to that of the arteriesdis-
tributed to the inferior surface of the pons and middle cerebellar peduncle. In either
region. two arterial stems are seen more frequently on the right (in 24% of cases)
than on the left (in 12%). This to explained by the fact that the posterior Inferior

The structure of the cerebellar arteries snows uetinite characteristics according
to age, such that In adults. as distinct from chiidren,there in observed a greater
tortuosity of the vessels In the shape of arcs and loops formed by the stems of the
cerebellac arteries in the various parti; of the cerebellum. Where 1here is a
strong development of the anterior inferior cerebellar artery and a high origin of
the posterior inferior cerebellar artery, the stems of the two arteries form extens-
ive arcs lying within the limits of the ponto-cerebellar angle. The wide arc tra-
versing the antero-Inferior surface of the pons. the middle cerebellar peduncle, the
flocculus, the biventral lobule and the tonsil, Is very often formed by the anterior
inferior artery and less frequently by the posterior inferior artery. Usually one
arterial stem is distributed to the antero-inferior surface of the pons, but two may
be found; in the latter case, the stems or the anterior Inferior and posterior infer-
ior arteries, or the stems of the anterior interior and medial inferior cerebellar
arteries. are most frequently distributed to the area mentioned. In the region of
the middle cerebellar peduncle the stems of the cerebellar arteries are distributed
in the same order as on the antero-Infertor surface of the pons. In the region of
the anterior quadrate lobule (onits anterior surface) a strongly devtlolied external
bran(h of the superior cerebellar artery can most frequently be observed, more
rarely (in 20% of cases) the stem of the anterior inferior cerebellar artery, some-
times together with a strongly developed branch of the superior cerebellar artery.
In the region of the flocculus one arterial stem is most commonly met with. Where
two arterial stems are distributed within the boundaries of the flocculus. they most
frequently belong to the anterior Inferior and posterior Inferior and less commonly
to the anterior inferior and medial inferior cerebellar arteries. The topography of
the arteries lying In the region of the flocculus in similar to that orthe arteriesdis-
tributed to the inferior surface of the pons and middle cerebellar peduncle. In either
region, two arterial stems are seen more frequently on the right (in 24% of cases)
than on the left (in 12%). This is explained by the fact that the posterior inferior
cerebellar artery (where it has a high origin) and the middle inferior cerebellar
artery arise from the basilar artery more frequently on the right than on the left.
In the pontocerebellar angle itself. the vascular formations are more marked on
the right than on the left. In the region of the tonsil of either side. one arterial
stem is most commonly distributed, rarely two. Where there is one arterial stem.
it usually belongs to the posterior inferior, and only rarely to the ante:"or Inferior
cerebellar artery. Where both arterial stems are present, they belong o the two
arteries mentioned. The stem of the posterior inferior cerebellar arter.1 quite often
fdrms a very well de"loped are or scroll lying on the internal surface of the tonsil.

A loopofthe descending portion of thestemofthe posterior Inferior cerebellar
artery, a~'Ising from the vertebral artery. is distributed to the medulla oblongata.
The distribution of the loop of the artery mentioned to the region co' the Postero-
lateral parts of the medulla oblongata and Inferior cerebellar peduncle is observed
on the left in 88% of Cases and on the right in 78%. The stem of the posterior Infer-
tor cerebellar artery In distributed in consequence of a high origin (from the basil-
ar artery) more externally to the medulla oblongata, on the left in 10% of cases and
on the right in 15%, in 216 of cases on the left and In 5% on the right this artery is
missing. The variability of the development and position of the cerebellar arterial
stems, and their anatomical relationships with the roots of the craniocerebral
nerves create a complicated topography in the area of the pontocerebellar angle.
The author in of the opinion that it in essential to deliTnit 4 arterial zones, which
should be characterized as danger zones where large arterial stems are concen-
trated. Theme are the zones of the pons, of the middle cerebellar peduncle, of the
flocculue and of the tonsil. Darbinyan - Moscow (VUl, 14, 18)

of the decay of liqaid solutions and of the study of the equi-
libr-ium of liquid phases one of the authors (Ref 1,2) already at
an earlier date worked out a theory of the meohan' m of the sepa-
ration into layers of liquids. This theory provides for three
stages of separation. In order to extend the applicability of
this theory the authors investigated the kinetics of the separa-
tion Into layers of liquids in the system n-nitraphanol - water
with stable separation into layers. It was shown that the laws
and rules governing kinetics confirm the correctness of the sug-
gested theory of the awohan4em of the nepamtion of liquids into
Oard 1/2 layers. Furthermore, the kinetics of the separation of liquids

ABSTRAM The theory of the mechanism of the process under review was
elaborated in systems with upper critical points (Refs 1, 2).
It may be assumed that it is applicable also to systems with
lower critical points (Ref 3). An experimental proofp
however, is required by the assumption that the latter
systems do not differ in principle from the first ones in
a particular phase equilibrium. That proof was the objective
of this paper. Therefore the kinetics mentioned in the title
was studied at I o w e r a t a b 1 e and 1 o w 9 r
m a t a a t a b 1 a critical points, i.e. in 2 kinds of
systems of this type. The system of phenol-o-phosphoric
acid was chosen because it is a doublo system with a stable
lower critical point, and has already been investigated as
Card 1/4 to the separation into layers (Ref 4). Pyramidon and water

The Kinetics of Separation Into Layers in Systems SOV/153-58-3-3/10
With Lower Critical Points
served as a double system with a metastable lower critical
point (Ref 5). The results obtained for phenol-o-phosphoric
acid are given in table 1, figure I and curve 1. The kinetics
mentioned in the title for the system pyramidon and water is
presented in table 3 and figure 3. For comparison, figure I
gives the curve of the separation into layers (P a) of the
systems investigated with a lower critical point K. The
dependence of the linear rate of extension of the separation
into layers on the superheating was studied in the same
mixtures (80.58% and 49-96% o-phosphoric acid) (Table 1,
Fig ij Curve 2). The latter curve is qualitatively very
similar to curve I and has a distinctly marked maximum. The
volooityzentioned increases by about the tenfold in the
transition from 80.58 to 49-96% o-phosphoric acid. On super-
heating in a mixture that nearly corresponds to the critical
point, the velocity mentioned is 3.5 times higher than that
to be found in mixtures which are near the edges of the
binodal surfaces. Figure 1 shows that superheating rapidly
Card 2/4 increases the linear rate of extension (up to the 14-fold).

With Lower Critical Points
Table 2 and figure 2 give the duration of the stratifica-
tion ofthe phases in dependence on the concentration of the
components in the whole concentration range below the strati-
fication curve.
C o a c 1 u 9 1 o n 9t In the systems mentionedi a) with
a stable stratification into layers and a lower critical
dissolution temperature, and b) with a metastable equilibrium
between the liquid phases and a lower'critical point it was
proved that the kinetics of the stratification into layers
in systems with lower critical points obey the same laws as
in systems with upper critical points. Thus it is confirmed
that in both systems the phenomenon of the separation into
layers takes place according to the same mechanism. Thus
the theory of the mechanism of the separation into layers
is fully applicable to systems with lower critical points
both in stable and metastable state, There are 4 figures,

ABSTRAM The transformation of stai)la separation of layers to the
metastable state can be of practical interest as a process
which makes it possible to obtain the fusion of two and three
bodies within the whole concentration interval of the binary-
and tertiary system formed by them. It is shown that this
transition in the ternary system takes place above the inter-
section and above the point of contact of the fusibility-
and separation- of-layer curves. As a whole, different types
of continuous mutual transitions of metastable and otable
separation of layers of binary and tertiary systems are in-
ventigated. They consist of four basic types represented in
the figures. The fourth type represented in fieure d ( ) has

that in both cases the volume of tl.c separation of lajors of

ABSTRACTt In recent time Dtable equilibrium was found between 3
liquid phasoo J-"'~ernary systems which are formed of binary
systems with stable phase separation.It was also shown that
also in ternari system which contains binary systems with
metastable phaue separation equilibrium can be established
between 3 liquid phases (Ref. 1). Here also the equilibrium
was metastable and was established according to the same
scheme as the stable phase separation, Stable equilibrium
between 3 liquid phases in a ernary system which contains
one or more binary systems with metastable phase separation
were not yet investigated. The research of this type of equi.
librium and of the scheme of its formation was the object

benzine was investigated as well; it pertains to the
systema with metastable phase reparation. The system water
- benzine belongs to the oyatems with stable phase oeparam
tion with an upper critical point which is to a great exa
tent positive (Ref.1). The system water - anthranilic acid
was investigated with resper,t to the phase separation. The
curve of the me ~astable phase separation has a lower criti-
cai point sq.70 C which corresponds to 38% of anthranilic
acid, Thus ternary system used contains 2 binary systems
with metastable and one system with stable phase separation.
The system anthranilic acid - benzine was investigated by
means of the melting point curve. The crystallization curve
is s-shaped and very steep; the form of the curve is due to
the existence of a curve for metastable phase separation.
This curve lies, however, at such low temperature that they
cannot be found experimentally. Their existence can, however,
be detected indirectly. It is shown that this system belongs
to the systems with metastable phase separation and a very
low critical point. The ernary system anthranilic acid - wam
ter - benzine was investigated by means of the phase separa.
tion. It was found that the reciprocal solubility of two

it was found that this system has a domain of stable equi-

low 1240C (temperature of the critical conode), Temperature-
concentration limits of the region of the three-phase liquid

that the scheme of the polythermal line of the occurrence and

with stable and metastable phase separation is one and the

TITLE: Employment of the Method of Two Solvents for an Investigation
of the Formation and Properties of Organic Complexes
PERIODICAL: Zhurnal obahchey khimii, 1959, Vol 29p Nr 8, pp 2490 - 2495
(USSR)
ABSTRACT: This theoretically founded method (Refs 1-4) in at present
being used - among other applications - for the investigation
of the chemical reaction in liquid systemel in addition, it
takes the effect of the medium into account. The above method
has hitherto been used but rarely for the investigation of
systems in which two complexes occur. To close this gap, the
two binary systems "chloral hydrate - antipyrine" and 11pyra-
midon - salicylic acid", previously investigated only in the
polar solvent water (Refs 5,6), are investigated here in the
homopolar solvent benzine. By V. P. klekseyev's method (Ref 7)
it was investigated how far the system ''chloral hydrate - ben-
zine" can be separated into layeral it belongs to the.systems
with an upper critical point (Fig 1). The system pyramidon -
benzine was investigated with respect to fusibilityl it is one

this connection two complexes of the predominant system appear
in the isothermal lines of the ternary system "chloral hydrate
antipyrine - benzine" (Fig 3). k complex of the predominant
system with the solubility minima, the upper ternary critical
point, and a break in the critical line appears in the iso-
thermal lines of the ternary system 11pyramidon - salicylic
acid - benzine" (Fig 9). k region of separation into layers is
visible in all three homogeneous binary systems whithin this
ternary system, a phenomenon which is illustrated in more de-
tail in the report. It was shown that in the investigation of
the complex formation in organic compounds with two complexes
the above method is reliable. It permits detection of all com-
plexes of the system, and determination of their composition
and a series of properties. It was further shown that of two
complexes that complex is most stable which contains a larger
quantity of the component of the reacting system which reacts
more weakly with the third component - the solvent. There are
