TITLEo The Isotopic Effeot in Compresuibility and in the Association
of Deuteroalcohole (Izotoynyy effekt v szhimayemosti i

PERIODICAL# Doklady Akadomii Nauk SSSR,1957,Vol,,114,Nr 39pp---590-593(USSR)
ABSTRACTs The paper under review is devoted to the investigation ct the,
ultrasonic vel8city a and 0of the density d in the inter-
val between 10 and 60 - 80 for CH OR and CH OD, and several
ot'hers, as well as for D2Oe The adilbatLc comiressibility...
and the osmotic coefficients were measured. The deuteroalco-
hole are obtained by hydrolysis, with heavy water, of appro-
priate alcoholates of magmesium and aluminum. The ratLo of the
cryoscopic molecular weight and of the molecular wei.-ht ob-.
tained from the formula decreases in the follovini;.orders
methyl alcohol, ethyl alcohol, n-butyl alcohol, as well as
nornal, iso-, and secondary butyl alcohol. For.deateroalco-
hols the acid ratio is by 2 - 5 % higher than for their hydro-
gen analo.-ues. Although it is not possible to derive any-
Card 1/4 accurate values of the degree of association from benzene

The Isotopic Effect in Compressibility and in the Association of Deutero-
alcohols
solutions of the alcohols, it is clear that the increaseof
the osmotic coefficients, with increasin,-, concentration in
alcohol, is caused by its de-ree of association. Therefore it
follows from the results of the cryoscopic experiments that
t~e deuteroalcohols are associated by the hidrogen bonds in
a hi~;her degree than their hydrocen analogues. This is also
confirmed by the higher boiling point of the former, and
also by the fact that sub3titution of hydrogen bj deuterium
in the alcohol hydroxyl leads to a reduction of its.vapor
pressure. The authors of the paper under review supported the
statenent macbby Tarasov that, generally speaking, compres-
sion does not take place on the relatively solid hydrogen
bonds but rather on the weaker Vandervaals' bonds between the..
chains (associates). Iso- and secondary butyl alcohol have
hi.-her compressibility than their normal primary analogue.
Therefore alcohols with a ramified chain are characterized
bj higher compressibility than the primary n-alcohols. In
all deuteroalcohols investigated the ultrasonic velocitYJS
by lo - 2o seconds lower than in the corresponding hydrogen
analogues. On the other hand, the coApressibility in the
Card 2/4 former is higher than in the latter. From the pointof view

20-114-3-38/60
The Isotopic Effect in Compressibility and in the Association of Deutero-
alcohols
described in the paper under review this isotopic effect.of
the compressibility means that in the deuteroalcohols the
intermediate chain interaction is somewhat weaker than in
their hydrogen analoGues. The occurrence of the temperature
minimum of the~curve of compressibility in water, as wells:'
as the presence.of the maximum of density, can be explained.
by superposition of two factors at the increase in temperature
and also.bj the transition of water from a more'strongly.
associated state into a less strongly associated state, with
a denser packing of molecules (reduction in compressibility).,
The authors of the paper under,reTiew maintain that, as com-
pared to normal water, the decrease in the degree of.asso-
ciation in heavy water is delayed with respect to tempera-
ture. In a way, the retardation of ultrasound in the sub-,
stances investigated, when hydrogen is substituted by deu-,
terium, is also caused by the increase in molecular weight

SOV/76-32-7-9/45
The Effect of the Substitution of Hydrogen by Deuterium on the Ultrasonic
Velocity, the Refraction and.the Viscosity of Benzene
In connection with this it was found that a substitution in
benzene of 91 ';" hydroeen by deuterium decreases the refrac-
t1on index to 2.1o-3 and the polarizability to 0#52 %. As
the zero energy of the C-D bond is smallor than.that of the
-!I bond a D 11 nubstituti increase of the
on causes an
Pnergy difference between the respective.excit6d and the
busic :Iectron.level; this fact is explained by obaervations
.:,.ade by ?urton ot ql. (Ref 15 and is proved'by experimental
d-.3ta obtained by Ingold and t7ilson (Ref 20). -Proceeding from
the eIquation according to Slaterand Kirkvood (Ref 21) it
is found th at a 91 hydrogen s ubs titution by deuterium
causes a decreaze ofthedispersion energy to OA a; on the
other hand it isjound.according to the data supplied by
'Nilkinson (Ref 23) that the equations according to.London
Ref-241 as well as those according to Slater and Kirkwood
Ref 21~ supply similar values for the,isotopic.effect-i .n the,

dispersion energy. The observed effects described were ex-

Since the dispersion energy becomes smaller in the hydrogen-
deuterium substitution also a decrease,of.the heat of vapor
formation isexpected which seems to be proved according to
data supplied by Davis and Schiessier (Ref 14) although those
data are doubtful. In the case of a.91 Cf
substitution of ben-
zene by deuterium an increase of the viscosity from.40to
5,5 014o was observed, and correspondingly less in the case of
a 50 vl~, substituted one; also an increase of*the vappr pres-

Kucheryavyy.* The propagation velocity of ultrasonic wavos and
.their density madependont on the temperature were measured for
the following deuterium compounds and the corresponding hydrogen

nitromethane, deuterium chloroform, methyl- and ethyl-iso-douttrium
propanolp primary n- and iso-deuterium, butanol, and deuterium
glycerin (deuterium in the bydroxyl groups). Since the publication
data on the sound velocity in heavy water are not in agreement,
measurements were carried out also in this field. The method of
light refraction was applied on ultrasonic waveagand the investi-
gations were carried out at frequencies of 3 Wes. The majority of

.substitution of hydrogen by deuterium in water and glycerin Is
explairod by the formation of three-dimensional lattices. In this

in equilibrium in the lattice) Is reducods and thus the molecules

isotopic difference of the activation energy of the viscous flow, which,~
in turni is exponentially relatedto the isotope difference of the zero-
energy of vibrations, which correspond to the hydrogen bond., The authors
thank Academician of the AS UkrSSR, A. 1. Brodskiy and Professor A. Z. Golik
for discussing the results of the presentpaper. There are 2 tables and 1,

TITLE. The Negative Isotopic Effeot~ in the Viscosity of.the

TEXT: An exchange of hydrogen by deuterium leads.. in the case of non-
associated liquids, to a change of themolecular weight and the energy-
of the intermolecular interaction. An increase of the two last-mentioned.,
values leads to an increaseof the viscosity of the liquid., Rabinovich
et al, showed that.in the range of..Medium temperatures, an increase in the
molecular weight in the substitution of hydrogen by deuterium.As
accompanied by a reduction of:,th,e intermolecular dispersion energy
(Refs 2-4), i.e.., that an increase)'but also a deer Iease in viscosity.,may
occur.due to.the isotopic exchange in dependence,on thefact whether the
increase in molecular weight, or thechange of energy of the inter-

The Negative Isotopic Effect in.the,Viscosity S/076/60/034/010/006/022

molecular interaction has.a greater effect upon the viscosity. The In-
vestigations hitherto conducted (Ref. 5) always led to,an increase ir
viscosity in the isotopic exchange. The present paper shows that isotopic
exchange may also bring about a decrease in viscosity. In chloroform and, .
tetrabromo methane the hydrogen was exchanged for deuterium and an,
increase in viscosity was found, i.e.,.in contrast to the cases hitherto
investigated a negative isotopic effect was observed. The decrease in
viscosity amounted to approximately I%- in both substances, which is five
times the error of me asurement, and.may thus be regarded as a reliable
result. Thus, it was clearly proven by experiment that an_increase~in
molecular weight due to the exchange of a light isotope.fora heavy one
may affect an increase, but also a decrease in viscosity. Finally, .the
author thanks A, I, Brodskiy, Corresponding Member of the AS USSR and,
Professor A. Z. Golik for discussing the results. There are 2 tables and

with 0.001* accuracy The C value was accurate to 0.5%. For the

domestic graphite, and acetylen? black. Hpat capacity was found,to
vary in the sequencel diamond/ -C &EALhLtelok acetylene black 4 carbyne.
Heat capacity of all nine carbyne samples was significantly higher,
than that of graphite, although different in each sample. This
differenc in C from on& carbyne sample.to another was correlated with
e p
the different ratio of the chain to laidellar structure, i.e., with
partial;fcrose-linkLng of carbon chains. The samples with highest C p
were assumed to have a low degree of cross-linking, therefore to bo
nearly linear carbon polymers, since the value of n in the formula
C - AT11 was nearly 1 for these samples. The n value for.other samples
p
was 1#2-1.5. Therefore, itwas concluded that the products synthe-
sized as described were different from graphite and had a lamellar-
chain structure. Orig. art. hast 2 figures and .2 tables. [JK]

ABSTRACT: The author of this work has previously presented a geometrical
synthesis which gives a representation of all the characteristics.
of the motio.n,,of an elastic system with one degree of freedom
under the action of an arbitrary disturbing force (Vestn. Voyenno--
inzh. akad. , 1937, Nr 20). In the paper under review the method
is expanded to.inclu,de the.action of forces of viscous resistance.
Another version of the generalized use.of this method for the
case in question is offered by V. 1. Gofman (V sb. : Issledovaniya

constructs the curves of the curvatures M/EI for the individual span
of the beam due to unit support moments, and computes the position,
of the area centers of these curves and the angles of rotation at the
supports.

ABSTRACT: It is noted that.in the design of a truss' having rvi members
a a un-
wherein n members are indispensable nd (m-n) re red
dant, it is always necessarv to make an arbitrary assumption
'or m parameters., Thus, for a slat ically--dete rminate truss
the stresses in all the mrn members are assumed. For the
design of a statically- indeterminate truss by the method of
forces the cross-sectional areas of aWthe m, members are
assumed; for the design by the assumed-stress method.. it is
the stresses (or the elongations) inthe n indispensable
members and the cross sections (or the forces) in the.(m-n)
redundant members that are assumed. In all these caie5 the
