TITLE: Investigation of the Kinetics and the Mechanism of the
Thermal Decomposition of Isobutylene (Issledovaniye

ABSTRACT: The third author (references 1,2) suggested a chain-reaction
of the thermal decomposition of olefines which is based upon
the redistribution of the H-atom between a radical of the
allyl-type and the olefine-molecule, where an alkyl radical
and a diene develop. He succeeded in determining from this
point of view the composition of the products of this
composition of olefines of various structure. It was,
however, not possible to extend these conceptions to the
cracking of such simple olefines as C 3H6 and i-C4H8 , as
no H-atoms capable of redistribution reactions exist in the
allyl-radicals developing of it . In another paper
(reference 2) the third author advocated the opinion that in
the case of the two above-mentioned olefines the formation

as one of the primary products. This quantity increases with
increasing pressure and with decreasing temperature. This
shows that the addition reaction of the H-atom to the
double bond of isobutylene takes place under the conditions
given here. In order to further determine the problem of the

cracking of mixtures of i-C 4H8. with C2H4was studied. The
results in table 1 permit the following conclusions;
1) They confirm the conception on the chain mechanism of the
reaction. On the other hand the development of ethane in large
quantities furnishes another proof that the transfer reaction
of the H-atom to the olefine double bond is possible. The
authors are of opinion that their tests confirm the assumed
reaction in isobutylene-crackings:

ABSTRACT: As is known, UP to 5016 of the initial substance in thermal iso-
~utylene dedomposition are transformed into liquids (olerins,
aromatic compounds). Apparently the polymerization or the
ihi'tial olefin forms the first stage of the liquid formation,
with dimerid and trimeric olefin being formed. The latter them-
selVds ar& capable of being transformed in various ways with
thb'f-inal result being liquid cracking products. The ratio
b`6tyiden carbon and hydrogen in these products is about 1 (Ref 2),
whereas it is 2 in isobutylene. From this may be supposed that
hydrogen and methane are separated in the formation of the
liquids; in principle, also heavier cracking gases with 2 and
Card 1/4 3 carbon atoms each in the molecule can be formed. The problem

The"ethylene activity determined in some experiments besides

this activity is much lower than that of propylene, this tends

Also ethylene can be formed either from isobutylene directly
or from liquids. Based on the experimental results obtained it
is not possible to make a decision as to the way of formation

TITLE: Investigation of the wear resistance of austenitic manganese
cast irons
PERIODICAL: Liteynoye proizvodstvo, no. 9, 1960, 36-38
TEXTs Austenitic cast iron containing nickel, chrome and copper pos-
sesses a high wear resistance and other valuable properties, but their cost
is high, and nickel is being replaced by cheaper and less scarce manganese,
copper, and aluminum. It had been discovered in laboratory tests (Lyadskiy,
V. B. - Ref. 24: Vestnik mashinostroyeniya, no. 3, 1951) that austenitic man-
ganese irons have a higher wear resistance than others and practice confirmed
that such cast iron with laminar graphite is several times more durable than
the usual pearlite cast iron. This article presents information on the re-
sults of laboratory tests of six differe... cast iron grades and OL4C6-6-3
(OTsS 6-6-3) bronze. The cast iron was melted in an acid electric furnace
and a small cupola. The chemical composition of the cast iron is given in
table 2; The A,, A2 and A 3 grades were austenite cast irons, and the B1 and

B2grades high-strength irons with globular graphite; C was grey cupola iron.
The Al, A2, B1 and B2 grades were treated by addition of magnesium and ferro-
silicon at 1,370 - 1,4200C; globular graphite formed in the Al, B1 and B2
grades. The A, and A2 irons were heat-treated, i.e. the 60 mm, diameter cast-
ings were heated to 1,OOOOC, soaked for 5 hours at this temperature, and
quenched in water. The purpose of the heat treatment was to dissolve the
carbides in austenite, reduce brittleness and hardness, raise the toughness
and improve the machinability. The specimens were tested for friction wear
on a MM (MI) machine, by sliding friction of a hardened steel roller on a
bushing of the cast iron being tested without lubricant. The article in-
cludes a set of photomicrographs and wear diagrams. In general, the test re-
sults have proven a considerable difference in the wear resistance, specific
friction and friction factor of the different cast irons. Austenitic A2 and
A3 iron with laminar graphite had a lower wear resistance than the Al grade,
but considerably higher than the B1 and B2 grades. Gray cast iron C had the
lowest wear resistance of all. The austenitio Al iron with globular graphite
had the highest resistance to wear. Apparantly, the wear of augtenitic cast
irons is lower due to the compact crystal lattice of austenite, its higher

plasticity and the formation of aear producto, corrosion resistance and ten-
dency to cold working that is connected with the transformation of auctenite
into martensite. Grey cast iron has no such properties and is more brittle.
Apart from this, it appears that the breaking off of metal particles by fric-
tion and wear is considerably easier on iron with laminated gaphite than on
iron with globular graphite. The author concludes that austenitic manganese
iron is a highly valuable material in mechanical eniSineering in viea of its
high wear resistance, moderate cost and good work properties. There are 6
figures, 4 tables, 20 Soviet-bloc and 7 non-Soviet-bloc references. The re-

or acid (orthophosphoric acid) catalysts. Physical and mechanical properties were
investigated. Melting point and specific viscositAof the copolymer are lowered
-fea-UT7ig. 1. Copolymers containing
with increased proportion of I, as illustra
more than 40A of I are soluble in alcohol and am be used for prepaxation of films.
The product is more highly elastic than polycaprolactame It can be manufactured '4 1
frod the melt by a continuous method on machines used for manufacturing film,?K-4,
mW-n its production even more attractive.
