ABSTRACT: This is a review of the literature dealing with water- and
alkali-soluble cellulose 'ethers used In the preparation
of thickening And stabilizing agents, glues, etc. The
solubility of carboxymethylcellulose Is determined basically
by the degree of its etherification and the de

by the-fact that 1h methylation in alkaline and neutral

replaced in methylcellulose compoundB (Soobshch. VKhOP
1955, Nr 3, P 9). Carboxymethylcellulose compounds
consist of fractions with different degrees of ether-
ification and polymerization. Industrial carboxymethyl-
cellulose nearly always contains an admixture of Slightly
soluble gel fraction. It was established (DAN SSSR, 1958A
Vol 123 "Nrr2, 289) that the individual fractions have
different stabilizing properties when used as stabilizers.

with the decreasing content of the gel fraction, not.-Nith-
standing the decreasing viscosity of the solutior (Izv.
vuzov MVO SSSR, Nef t I I gaz, 1959,, Nr 6). The viscosity
depends on the.fraction content, and also on the degree of
etherification (DAN SSSR, t959, Vol 126, Nr 5; RZhK`h, 1957,
P 10029). With Increasing degree of etherification (
20-to 200) the viscosity increased to a maximum, decreased

TITLEs The Structural Viscosity of Aqueous Solutions of Carboxymethyl

PERIODICALt Doklady Akademii'nauk SSSR, 1959. Vol 126, Nr 5, pp 1025-1028,
(USSR)
APSTRACTs A previous paper (Rof 1) pointed out that carboxymethyl cellu-
loss (CMC) exhibits anomalous viscosity at concentrations ex-
ceeding 0.1% in aqueous solutions. Now the effect of the indi-
vidual fractions of CMC rith varying degree of polymerization
are investigated with respect to the structure of the solu-
tion. Four samples were seleatedt (1) high-molecular, (2) gel-
3haped, (3 ) sol-shaped, and (4) low-molecular CMC (Table 1).
The viscosities measured at different velocity gradient G
viscosimeter by Pinkevich) confirm P. Happler's opinion

Refa 20)t i.e., the viscosity of high-molecular CMC depends
~
on G, and this dependence increases with increasing concentra-
tion. Sample 2 shows the hiShest degree of anomaly, whereas
Card 1/3 sample 4 exhibits the least dependence on 0 (Table 2). Accord-

The Structural Viocosity of Aqueous Solutions of Carboxymethyl Cellulose
ing to Pasynekiy and Rabinovich (Ref 4) this structural viscosi-
ty can be represented by the tangent of the angle of inclina-
tion a in the coordinate system -r) - IgG, Table 3 gives the
values for'tga and besides the calculated dynamical shearing
stress 0. It i; concluded that the structural viscosity is caus-
ed by the gel fraation and the interaction of the gel particles.
The attempt was made to eliminate the Interaction of gel parti-
cles by the addition of sample 3 or 4 and by adsorption of the
low-molecular particles to the gel particles. This was a success
as figures 213P4 and table 5 show. Only at high concentrations
of sample 4 viscosity Increaaes again, which is explained by
complete saturation ofthe gel particles. Thus, the increased
concentration.of the CHO becomes effective. The results obtained
show that by a proper arrangement of CM0 fractions it is poB-
sible to control the properties in the deuired way. There are
4 figurest 5 tablest and 7 references, 4 of which are Soviet.

Na-CMC, however, was negatively characterized since it causes

synthesis of such preparation& which also would yield good
results with regard to their bomodynamic propertias.
CMC preparations can be produced with different polymerization

_CMC preparations with different PD- and ED-values wore obtained
by esterifioation of pulverized alkali cellulose with sodium
monochlorine acetate. The quantity of the esterifying agent
'depends on the PD of the original alkali cellulose. Table 1
shows that, at the same ratio of the reagents, with a lesser
PD of alkali cellulose higher Me are attained. The desired ED
can be obtained by a limitation of the sodium monochlorine
acetate consumption, as this reduces the PD of the initial
cellulose., 'For the synthesis of blood-substituting solutidne
only ohemioally.pure CMC preparations can be used. An instruction
for the purifioation,is given. In order to obtain a complete
solubility the ED of CMC must be high; values of 70-05 do not
.influence the blooil-substituting properties of CMC (Ref 5)- From
among the CMC preparations tested (PD of 240 UP to 58) those
with values between 70 and 100 were the most efficient ones

In order to, accelerate the, destruction process of the alkali
cellulose that requires a lot of time, by atmoepheric oxygen
(Table 2)f hydrogen peroxide Is added to the morcerization bath
or to the alkali cellulcae euring the pulverization. The results
of the experimenteare given in table 3. Small quantities H 202
~(up to 1-5%) do not influence the blood-substituting properties
of CMC. Large amountsp ifadded directly to alkali cellulose,
turnCMC preparations toxic, and animals are killed if they are
intravenously injected. The increase in the toxic effect cannot
be explained by a modification of the average chemical
composition. Mostprobably it is a consequence of the unequal
destruction process as well as of the.agglomeration of a certain
quantity,of highly-oxidized cellulose by which CMC preparations
become toxic. For thisreason, H 0 must be used very carefully
2 2
for the above-mentioned purpose. For the purpose of reducing of
the PD below,100 the finished product vras hydrolytically cleft

process depends on the initial PD of CMC preparations.,Good

in those already existing. In all the diagrams described in

TEXT-..' A,method of determining hydrogen in helium according to the ad-
sorption development,chromatography was elaborated. The experiments
were made on a XT-2M (KhT-2M) chromatographic instrument with a developer
.based on the thermochemioal,prinoiple (Ref. 1). The working conditions
were selected in such away that a detector could determineboth com-
ponents by two characteristice, i.e., helium by the thermal conductivity
and hydrogen by the heat of combustion. A 6 m long metallic separation
columnp filled with CKT (SKT) coal and with air an carrier gas, was used
for analys6s,at room temperature. Tho sensitivity to hydrogen amounted
to 6.5% at a relative accuracy of 5%. A 10 m long.polyvinyl ohloiide
tube was used for analysee,at low temperatures and work was carried out
