ABSTRACT: . The article presents the results of an investigation of the protective
properties of certain inhibitors (nitro- and dinitrobenzoates) synthesized at the
authors' laboratory; these properties were tested in natural atwell as accelerated
conditions involving cyclic and continuous exposure to moisture, with the aid of a
specialty developed device (Persiantseva, V. P., Rozenfelld, 1. L. Zavodskaya
laboratoriya, 1958, 24, 7, 282). (The tests under natural conditions simulated the
conditions under which metal products are stored in unheated warehouses and lasted
for 21 months.) The inhibitors investigated were: hexamethyleneimine meta-
nitrobenzonte,._hexmathyleneimine ortho-nitrobenzoate. hexamethyleneimine 3,5-dini-
~iolienzioste-.--aod-p~ppr~4i a 3.5-dinitrobenzoate.. The coating of metal surface with

.specimens In alcohol solutions of the inhibitors with subsequent drying at room
temperature. Protective properties were determined according to the time elapsed
until the appearance of first signs of corrosion and according to corrosion rate (as
determined by gravimiatitc method). Findings: When applied in the form of alcohol
solutions, all the four tested chemicals proved to be effective,inhibitore of
atmospheric corrosioil under conditions simulating storage of metals In unheated

not only ferrous metals but also the most widely used nonferrous metals, (Cu and its
alloys, Ag, Sn, Al and its alloys, Wi and Cr coatings, and Zn and Cd coatings

considering that preiriously the only other known volatile inhibitors used in industr

ABSTRACT: This consists essentially in obtaining full pa;3sivation potential not by
decreas~.ng the reaction rate at the anode but by zha--ply increazixig that at the
cathode; it requ~.res inhibitor reduction with sufficient opeed in a neutral.medium.
Organic salts am c:apable of shifting the stationary potential of iron by 300-400
millivults towazila the positive side without oigaifieantl~f ahanging the rate of
metal ionization at the anode; this applies in particular to c&rbo.Vl and secondary

Anothe-r requirement, for protection, besidea electrochemical reduction, io the
adsorptiDn of organic cations by the metal surface. If this adsorption reaches
a sigaificant level. the specific currert vill easily attain tho critical value
required for the paasive iron atate. This requirement is met by organic salta of
dinitrob-2nzoic acid containing canily abaorbcd organic cations and reducing the
uitrite group w-ith oufficient speed. This now principle is applicable with electro-
lytes containing a low activator concentration (chlorine ions). The chemical reac-
tions involved are presented and discussed for 2 inhibitors representing the 2
kinds of protection: dicycloheVlamine nitrite and the above-mentioned compound.
The first shifts the stationary potential towanle positive due to considerable
checking of anode reaction; the Becond achieveo the same by accelerating cathode
depolarization. In dilute electroly-tes thia latter will also decelerate anode
ionization reaction. A new addition to inhibitor classification is thus required,
i.e. the claso of cocrpolmdo affordinC;, metal protection by accelerating the process
at the cathode. Orig. art. haD: 3 figures and 2 formulas.

APSTRACT: Tl~i:.s ;,aper deals with the investigation of the electroche~:i-

method of I. L. Rozenfelld (Ref 3). This method was improved
in such -~ manner that it was possible to apply electrolz~te
films to the electrode surface after it had adnorbed the
inhibitor from the gaseous phase without violating the
hermeticity of the space. The volatile inhibitorn investir,.at-
ed in this paper are benzylamine (C 7if9N) and morpholine,

~.ciine. The adsorption of the inhibitor moves the steady po-
tential towards the positive side. If the timme of the soakin..7
of' the electrode in the atmosphere saturated ~,,y the inhibit,~r
vt.pors increases, the observed effect increases, too, After
a certain time, this effect acquires a constant value. The
surface, obviously, is then totally saturated with the
inhibitor and the potential is displaced by more than 200 mV.
If there is a thin layer of electrol,.te on the tiurface of
thu metal, the adsorption of the same inhibitor from the
ra3eous phase causes by far less intense effects. In this
ca:3e, the potential of the iron is displaced only by 50-60 Mv.
The adsorption of the inhibitor from the gaseous phase, there-
fore causes more noticeablA variations of the potantial and,
povsibly, also a higher passivation degree of the electrode.
The adsorption connettion of the inhibitor with t.-ie netal
surface and the stability of the passive state may in a certain
depree be characterized by data concerning the time dependence
of the potential of the metal after the saturation of the
electrolyte film attached to this surface. If the time of

TITLE: The Effect of Some Factors on the Rate of Atmospheric Corrosion of

ABSTRACT: The author studied the effect of moisture, C02, S02 and the presence of
solid dust particles on the rate of atmospheric corrosion (RAC) of
Mg and the Mg-alloy of the composition (in %): Al 6.5. Mn 0.3, Zn 1,
which has been passivated In an acidic bichromatic bath containing
NH4C1. The study has shown that RAC of these materials increases sharp-
ly at an increase in the relative humidity to 90 - 95%. An intensifica _ V
tion of' RAC of Mg was noted in an atmosphere polluted by C02 and S02, in
which case the joint presence of both gases leads to higher corrosion
losses than in an atmosphere containing these gases separately. Particles
of coal dust promote the corrosion in S02 and almost do not affect the

ABSTRACT: The add mentioned is characterized by the fact that it causes the
"phenmenon of mould" in the nickel electrolyte. Por the purpose of
determining it, it is recommended to oarr7 out aeparation of niakel
from the electrolyte chromographically by the application of the
cationite "SDV-3". For this purpose an adsorber wan munted in a
qylindrical vessel (filter) of 15 mm diameter up to a height of
2W mm. The electrolyte was made to pace through the adsorter with
a velocity of 100 ml per 20 min. After nickel adsorption was oomple-
ted the filter was rinsed out while the same velocity was maintained
for 10 minutes. The analysis itself was then carried out: 5 ml of
the electrolyte was dissolved in distilled vvater of up to 2D-25 ml
tOtELl Volume and sent through the adsorption filters. The filters
were, rinsed out with distilled water; the solution together with the
Card 1/2 rinsing water was introduced into a platinum vessel, where 10 ml

until the aediment became dry# which was then melted at 320 + 2
To the cooled Malt 35 ml of uitmtiag volutionj 10 g nitrate-of
ammonium in 100 ml hydrochloric aoia having the specific weight of
1.4-1-82 was added. After the strong reaction hereby caused had
ended, distilled water up to a volume of 100 ml was added. The solu-
tion, which in this case wan of yellow color, was colorimetrized by
a blue light filter. According to the previously prepared gauge curve
of determination, the naphtalene sulphide acid omtent (volume) was
determined. The method described is distinguished by its high
accuracy. There is I table.

ABSTRACT: Various authorc. have pointed out the po,,;~,ibility of
producing a bribht cc7,per platinL, from cyanide and
acidic solutions (Rof 1). Much attention to this
proble;:i is paid in an earlier pLiper of the tea.ii of th,~
authors of thi-~ paper (Ref 2) in %,.,hich it ivas shown th-t
the most intensive cc:ilpooent of an acidic electrolyte
briiibin8 about bri,htnesi, iL~ thiourea. However, if a
certaLi a,1--it of U-iourea is present, the precipitat(-:E
will be ver.i brittle unserviceable for la~,er

sugge3ts that a break of the i.-rystal lattice destroys the weak Van der Waals
