"Investigation of Factors Influencin.rr the Hemagglutinational Characteristics

-ludapest, Kiserletes Orvostudomany, Vol XV, No 3, June 1963, PP 319-325-
Abstracti [Authors' Hungarian summavr] The influence of temperature and
PH on the rat erythrocyte agglutination by type 9 adenovirus was examined.
Of five temperatures tested ( +40C, R.T., 370C air, 370C and 400C bath),
40C and room temperature were optimal. The results were confirmed by ex-
periments with types 10 and 13 of the virus. The effect of pH on the hem-
agglutination was tested at pH 6, 7, 7.5, 8, 8.5, 9 and 10. The optimum
was found to be pH 9, 8.5 giving results close to the optimum. The sen-
sitivity of the erythrocyte suspension to hemagglutinin was not impaired
'by standing, It even increased slightly between P11 7-9. If equal amounts
of the virus are used, the hemagglutination-inhibiting reaction was not
influenced by PH. 5 Hungarian, 7 Western referoneca.

Title Upon the Y-tnetics and the Equilibrium of the Equilibra-
tion Reaction of Linear Methylpolysiloxanes.
Orig Pub: Z. phys. Chem. (DDR), 1957, 208, No 1-2, 33-41.
Abstract: It is shown that the earlier derived equation (part
1, RZhKhim, 1957, 53965) for the distribution of
linear methylpolysiloxanes according to the mole-
cular weight in the process of attaining equilibrium
can be generalized for the case cf any bifunctional
initial substances containing D units.

TITLE: Hydrolysis and polycondensation of mixtures of methyl-
chloro silanes of high functionality
I
PERIODICAL: Magyar Kemiai Foly61rat, no. 2, 1961, 82-85
TEXT: The functionality of polycondensates of organic chlorosilanes is
determined by the chloride content of the chlorosilanes used as initial
substances. There are many publications on polymers built up from
bifunctional groups, their formation and physicochemical properties,
whereas there are no published data on systems with much higher average
functionality than two, and a C/Si ratio smaller than two; the latter
are practically used under the name of silicone resins and silicone
varnishes. The authors studied methyl siloxane systems formed in the
first reaction phase with high average functionality. They looked for a
quantitatively measurable property of the hydrolyzate, which depended on
the parameters characterizing the hydrolysis, and thus permitted the
determination of a relation between the conditions of hydrolysis and the
Card 1/0~

properties of the product. Experience has shown that the result of
hydrolysis, or of primary polycondensation, is mainly determined (1) by
the average functionality of the.system, (2) by the functionality differ-
ence of monomers, (3) by the pH of the hydrolyzing medium, type and con-
centration of dissolved cations, and (4) by the method of hydrolysis.
It is known that the effect of average functionality does not only appear
in siloxanes but also in other high polymers. The functionality, however,
differs very much for various systems of monomers. Table 1 gives the gel
formation capacity of hydrolyzates with a C/Si ratio = 1.3 obtained from
(CH (in the following D) and CH Sicl (in the following T) on theone

hand, and from SiCl 4 (in the following Q) and (CH 3)25icl2l on the other.
Gel formation capacity means the percent by weight of the part of the
condensate unsoluble in the organic solvent, which had passed from the
sol to the gel state. The polydisperL'ty of the'system increases with
the functionality difference of monomers. From the point of view of co-
condensation, it is convenient to conduct hydrolysis with a small amount
of water dissolved in the organic solvent since both the rate of hydrolysis
and that of polycondensation drop in this case. When conducting the

hydrolysis with pure, water-saturated butyl acetate at a dropping and
mixing rate at which constant equilibrium is maintained, it was possible
to obtain fully reproducible results. With rising pH and in the presence
of magnesium ion, the polycondensation rate drops,. and co-condensation
is thus promoted. The diffusion constant was determined with an apparatus
described in Ref * 2 (0. Lamm: Nova acts, Reg. Soc. Sci. Upsala, 10, 69 1937)
and, since the 30Ax - x curves yielded no ideal Gauss curve (Fig. 1),
the constant was calculated by the moment method described in Ref. 3
(N. Gral6n: Kolloid Z., 95, 188, 1941) from the relation
2 c1 -
M2/(Mo.2p t) = '/(cl-c2) f Ddc = D , where Mo is the zeroth moment, i.e.,
C2
the planimetrically determined area below the curveg t is the time in sec,
c is the concentration (g1100 ml of solution)9 and P is a constant, in
2
this case equal to 10 . The diffusion constant is a function of concentra-
tion. It rises noticeably (Table 2) in hydrolysis in a basic or buffered
medium. Magnesium ions have a similar effect on hydrolysis as a rise in pH.
In the concentration range of 5-8%, U is practically independent of the

initial concentration co, -and the numerical difference of diffusion
constants drops. For the further evaluation of experimental data, the
Boltzmann method was used, the Upplicability of which was proven (Fig. 2).
Some typical data are given in Table 3 and Fig. 3; they show that a rise
in pH in the hydrolyzing medium always effects an increase in the diffusion
constant referred to the same concentration, except for the concentration
range with small D0. Hence, it follows that the diffusion constant of
the primary hydrolyzate rises with the pH and in the presence of certain
2+
cations such as Mg . It is known, however, that the increase in the
diffusion constant in solutions of equal concentration corresponds to a
decrease in the mean molecular weight. The established shape of the
diffusion curves with a minimum indicates that besides the osmosis factor
also the hydrodynamic factor iii of importance (Ref. 5: J. Rosenberg,
and C. 0. Beckmann: J. Ann. N, Y. Acad. Sci., 46, 209y 1945), which is
due to the fact that the siloxane skeleton also contains silanol groups,
the presence of which was also proven by several other authors. The
decrease in the mean molecular weight of methyl-siloxane sols with rising

pH in hydrolysis, as well as the drop in gel formation capacity in Q-D
systems under otherwise equal conditions indicates a decrease in poly-
dispersity corresponding to the increase in co-condensation. This paper

PERIODICAL: Magyar kemiai folyoiratX no. 10, 1961, 450 - 454
TEXT: The article deals with investigation of the pol-,, 7meriz-
ation process using a thermolyzing catalyst. The authors ex-
perimented with the polymerization of octamethylcyclotetrasil-
oxane with a tetramethylammonium silanolate catalyst carried
out in N2 stream free from C02 and H20 at 80 - 1200C, to obtain
dimethyl polysiloxane. Experiments with o'etamethyleyelotetra-
siloxane treated with HC1 and N~ and witb unprepared octamethyl-
cyclotetrasiloxane proved that he polymerization rate and the
average molecular weight of the product are dependent primar-
ily on the purity of the reacting substance. Results of ex-
periments with four different samples, given in Table 1, show
Card 1/ 9

that purified sample-z give a higher molecular weight in a shor-
ter time than the unprepared samples. Another series of ex-
periments with samples obtained from the distillation of pur-
ified octamethylcyclotetrasiloxane, revealed that the molecular
weight of samples from the first and last fractions was lower
than that of the main fractions. Data of this experiment are
shown in Table 3, where the samples from the first fraction are
marked 1 to 7, from the last fraction 35 and 36, and from the
main fractions 7 - 34. The molecular weight of the polymerized
product depends on the N to Si proportion of the mixture. The
relation between the molecular weight and the N to Si is shown
in Fig. 1; the dashed line represents the N to Si values com-
puted by a method previously used in polymerization of octa-
methylcyclotetrasiloxane with potassium silanolate and descri-
bed by F. T8rbk and P. G8m8ry (Ref. 6: Magy. Kelm. Folyo'irat,
66~ 707 1960). The authors suppose that the difference between
the experimental and computed values is caused by functional

impurities. The molecular weight is also affected by deca-
methyltetrasiloxane. This property of decamethyltetrasiloxane
makes it possible to obtain the required molecular weight which
is of considerable significance in silicone rubber production.
The influence of tetramethylammonium silanolate on the thermal
stability of the products was examined by thermogravimetric
analysis; data are shown in Fig. 31 in which the curves marked
18/3 and 20/3 represent samples polymerized with potassium
silanolate, while the curve marked 95 represents a sample
polymerized with tetramethylammonium silanolate. The authors
express their appreciation to the management of the Nitrok4mia
Ipartelepek (Nitrokemia Chemical Works) which provided the raw
material for the experiments and to Uroly AlmXs, shop manager
for his help with the experiments. There are 5 tables, 3

ABSTRACT: The corrosion of the zinc electrode in a zinc-
platinum galvanic element with anhydrous methanol electrolyte increased
upon the superimposition of alternating current onto the direct current
.generated by the galvanic element. The extent of the increased corrosion
was dependent on the voltage and the amperage of the alternating current,
and also on its frequency. The frequency vs. corrosion increase effect
shows a maximum at a rdatively low freqxiency level. The electrolyte, being
perio.dically reduced and oxidized, contributes to polarization phenomena.

Abstract The physical and chemical conditions of the formation of
the brown iron-ore deposits of the Byorzhyon' Massif
were investigated, A description is given of the geolo-
gical structure of the region, of the conditions of stra-
tification: and of the forms of the appearance of the
ores. The ores were formed by means of erupted rocks
(andesite) dacite). After the division of the limnite-
hydrohematite-goethite ore during the course of past de-
hydration, there occurred a -filling-up of fissures and
cavities with mixtures of limnite) goethite., lepidocro-
cite, hematite, and siderite, with limonite predominating.

A' important preliminary condition was the presence of
a closed, drainless basin of the lagoon type, in the stag-
nant waters of which Fe ions accumulated in the presence
of suitable absorbing or UccuuIlating rock (sand, andesi-
te tuff). Another favorable condition was a climate with
a moderate anount of precipitation; abundant rainfall
could have led to strong dilution of the basin's waters
and to a decreased Fe content in them. The admission of
the-rmal waters accelerated the separation of the silicate
portion of the rocks, through the circulation of Fe and
its accuraLlation along the crevices or on the surface.
In every case, the accuiiulation of ores originated over
impervious horizons (clay, compact andesite).
Weathering played an important role in the enrichment of
the ores.
