TITLE., Refining of germanium dioxide
PERIODICAL: Chemick)(prfimysl, no.2, 1962, 6o-63
TEXT; For semiconductors extremely pure germanium of
99.99999999999% purity, usually called "eleven nines", is required,
The production of this pure metal, carried out by reducl:ion of
germanium dioxide and zone refining of obtained germanium, is
economical only if an oxide with at least three nines is used-as
starting material. Therefore, germanium dioxide is refined for
the ellmination of various contaminants, above all of arsenic.
The following preliminary refining methods were studied on a
laboratory scale: 1) elimination by reduction with Zn, Al or SnC12;
germanium tetrachloride is unaffected by the above redui:ing
agents, while AsC1.3 is reduced to arnenic; 2) absorpt;Lon of
AsCl3 and GeC14 in carbon tetrachloride, followed by oxidative
extraction with HC1 and HN03, In this procedure AaC13 is
oxidized to the waiter-soluble Hi;AsO4 which can be extracted with

wntart 3) extraction of crude GeClk with 11CI + UN03;
4) separation by fractional dist.illationj 5) fractional
distillation with simultaneous oxidation or reduction. The
authors have now selected the distillation procedure, combined
with absorption in CC14 as a basis for further experiments on a
semi-technical scale. The purity of Ge02 obtained aftor
hydrolysis of the distillation absorbate in CC14 was 99,,9%, which
is considered satisfactory in view of the fact that ordinary glass
apparatus and ordinary distilled wateir were being used. The
material was further refined by oxidative distillation vrith HCl
and HN03, using an electrolytic heating arrangement. (Heiating in
an oil bath proved unsatisfactory because of settling of' GeOq.)
The degree of refinJng was found adequate for the final zone-reftiting
process, It is submitted that further improvements in refining
could be achieved by using silica. apparatus for the hydrolysis and
hard glass for the distillation. There are 2 figures and 3 tables.

TITM :Determination of Water Content in the Cosmetic
Fmulsions.
ORI(;. MjB. Prumysl notravin, 1957, 8, No 7, 371-373
ABSTRACT Proposed is a new analytical determination method
of water content in the cosmetic emulsions. 0.1 gr
of cream is placed on the preweighed glass plate
followed by drying at 700 until its weight remains
constant. When temnerature is increased to 800 the
determination error increases. It is recommended
that 5 parallel determinations be carried out
simultaneously. The method nermits the determina-
tion of water in a relatively small samplet and
the analysis requires far less time than the me-
thod that involves drying with sand. The method is
very simple and does not require itrecial apparata.
nor special reagents, - S, Voy-tkovich.

TEXT: A patent is granted for a device for direct conversion of graphic
recordings (images), e.g., osclllographic, mechanical or photograph.tc recordings,
Into an electrical voltage. The device dispenses with the need for mathematical
processing and the use of qualified manpower. The essence of this Invention
(nee Figure) consists In the use of a rotary drum (1) w4iose lateral svrface'hav
slits (2) running parallel to the drum's hollow rotating axle (3). The axle (3)
Js rotated by an electric motor (5) through a transmission mecharism (4). In-
side the drum (1) there is a photocell (6) fixed on a holder (7) tbrvgh which
wires (13) are led to the photocell (6). On the mounting board (8) of the de-

vice there Is an illuminating Unit consisting of a lamp (9), a ground-glass
screen*(10), and a frame (11) serving to hold the image (12). The illuminating
unit is enclosed by a casing (14), the drum (1) is covered by a cover (15), The
graphic image, taken from the measuring instrument, is made by any suitable rp?th-
od, so that its width corresponds to the distance between neighboring sl1ts (2).
The lower part of the image is blacked out, and the upper part is cut around Lts
contour, after which the image is inserted in the frame (11). When the drum (1)
rotates, the luminous flux from the lamp (9), falling onto t.he photocoll (6)
through-the slit (2), Is proportional to the ordinate of the graphic 1:12); the
voltage appearing at the photocell output is thus proportional to thin ordinate
and can be used for~any pprpose. In a variant of the device it in pol,nted out

This review is basically conaerned with reaction schemes
of velocitles of processes occurring in a homoganeous
fashion in isochoric and isothermal systems. The major
part is based on velocity equations of chemical reaction.9
occurring in solutiono The rev W'seen the taolk of his
review as being that of surveying reaction schesnes which
have to be solved from the kinetic viewpoint and special
attention is paid to the mode of determination of the
velocity constant. The presentation was datert:LLned by the
fact that in contrast to the majority of other chemical
problems, it Is sufficiently difficult to obtain
information on the kinetic treatment of specifia reaction
schemes from abstract journals or monographs. 7me reason
for this being the case with such abstract JoW7:aals as
Chemical Abstracts and Chemisohes Zentr *alblatt Lies, on
the one hand, in the difficulty of conveying adequately
the majority of complicated reactions in a.condensed forin
and, further, in the fact th-st quite alnumber of solutionn
are Scattered through the texts. Monographs tead to give
Card2/19 incomplete Information.

Classification and grouping of reaction schemes adopted
by the reviewer were previously suggested by Min in Ref 2111.
Various other methods are to be found in Refs 41, 153,
11-13, 26, 27.
First-iarder Reactions Bases: linear systems, cyclic
systems; combination of two linear systems.
Linear systems - Nr 1 is allocated to that subatance on
the edge of the system which is formed and then suffers
maximum change.durizxg thereaction* This substance is then
said to have maximum "disturbance". For examplo,
substance A,-k'-' has priority tn allocation of index 1 to
substance A4 and this, in turn, has priority over Ae-
Numbering of other substances is carried out in a systematic
way.--Further principles arise from the steps taken to
allocate the "disturbed" position Un the sense of the
above) the lowest number. This principle must,be respected
.in all-the following sx3tems, as well.
Card3/19

Cyclic szotems. Nr 1 is allocated to the substance with
maxiinum "disturbance" -(e.g. substance ::AV! has
precedence over avbstance --PA;Et substance t4A:O hais
priority over aAdi:= , etc.)-
Combination of two linear systems After selocting the
longest linear system the rules given above are followed
and -in addition the side chains ar e numbered f.-rom the
main system in the direction of the free end after the
main chain has been numbered, The designation W-reaction
scheme is derived by writing the existing procasses in the
given reaction scheme. Sach elementary reactimn (reaction
of type Am--3,An) is described by the double wymbol
M-n 0 A set of elementary reactions forming the given
reaction ichem6 is.wr1tten as a set of double nunbers: the
arrangement of the double numbers m-n (small.b.r numberm
have precedence over higher numbers, e.g. 1-2 has
precedence over 2-1; 2-7 has precedence over 3-4. etc.)
gives, in the main, the design&tion of the reaction
scheme. In the case where the substances yield double
Card4/19 numbers (e.g. in a twelve-component system n := 12 ) the
06624
CZECH/8-53-1-20/20

index is designated with a bar (12). The complete
symbol of the reaction scheme is obtained by placing the
set of dual numbers in brackets and the order of reaction
is designated by a Roman numeral and the number of
reacting substanc(a in Arabic numeral in-heavy type.
Example:
Al --* A2 _v. A3
Is designated 13(1 - 21 2,- 1, 2 - 3) 1 shows that
the reaction Is first order; the number of substances
participating in the system and the numbers inaide the
brackets show that substance 1 gives rise to sifbstance 2,
substance 2 to substance 1,-as well as substance 3.
Classification of reaction schemes. With a ratiotion of the
given order the symbols are Zrouped in the firat place,
according to the number of substancesi the sytibols
describing the systems with fewer substances have precedennee.
Card5/19
06624
cz ccti/8 -5 3 -1 -2012.0
Kinetic Equations of Homogeneous Reactions .
In the classification of symbol groups of the reaction
schemes of a given order and a given number of substances,
the rule that symbols dealing with a larger nwiber of
processes have precedence over symbols dealing -w1th a
smaller number of processes- applies. - This meaiLs, in
practice, that we proceed from the more complete to the
less complete systems. For the same number of processes
the size of the first dual number is decisive, as long as
they differ, or the i-th dual number, if the (i - 1)
dual number coincides. In this case, the lower dual
number has precedence over the higher dual number.
Reactions of the Second Order. In the-case of aecond-and
higher-order reactions (as in combinations with first-
order reactions), th'e relationships are more couiplex. As
in the case of first-order reactions the numbering of all
componenta of tho roaction syntom is carried out progronn-
ively, so that the numbering of componento in conunenced at
the "end" of the longest linear system so that the
"interfering" positions are assigned the lowest number.
Card6/19
06624
CZECH/8-53-1-20/20
Kinetic Equations of Homogeneous Reactions
In the case of consecutive-reactions the index of the
substances is progressively assigned so that the rule
that the "interfering" positions are given the lovest
number is taken into account. In the case of first- and
second-Drder side reactions the rule applied is that
second-order reactions have precedence in the msaignAtio:n
of indices. Of course, with first-order reactions, two
numbers suffice for the simplest reactions, e.g, A 1 -41 A
has the symbol 1 2 (1 - 2) but in the descriptlo.m of
second-order reactions at least four numbers, grouped Into
pairs, are required, e.g. A I + Aa -0 A3* A4 has the
symbol 114(l2 - 34) - II indicates the order of reaction,
4 the number of substances involved in the reartion; the
contents inside the brackets indicate that A I and A 2
give rise to A 3 and A . Reactions systems which are
built up from a number oi first-order reaction3

-and-only one -second-order -reaction- are class1fii3d_
together with second-order reactions; reactionis of the
first-order being written formally as reactions of the
second-order, e.g. a first-order reaction A. -~A n
which forms part of a second-order reaction syn-tem.has
the symbol mO - nO. Reactions of the second order of
type 2A,--)oA2possess the symbol 11 - 20.
Classification of reaction schemes. In the case of
sacond-order reactions classification proceeds Ln a
completely similr way to that for symbols of fi.rat-order
reaction schemes. This mean that the scheme isymbol is
arranged first of all according to the number of sub-
stances describing the sche*e; scheme symbols -with fewer
substances have precedence over those scheme isynbols
involving more substances. Further, in groups of symbols
describitga certain nil ber of components, the completeness
of the system (the more complete system having precedence)
is the deciding factor and with schemes of the same
Card8/19 completeness the deciding factor is then the size of the

first of the four numbors (algain smaller numbera have
precodonce). The arranging according to size oT the firat
of the four numbers is retained in the case whore the nwnber
of products is larger than two, e.g. with
A1 + A2 --~ A34 A4 + A5 has the symbol 11 5(12 - 345), the
arrangement 12 - 34 is the deciding factor. In-prInci-le,

of the velocity equation in its differential fo:rm doGs not
encounter the-usual difficulties (but e.f. Refa 29, 30,

In this equation (Ail denotes-the concentration of
the substance. It is pexvdasLble to use the statement
of concentr&tion on the assumption that the res,ctlag
substances exhibit ideal'beha-Wour and thia tacit assum-
ption is, as a rule, accepted (for the general formulation
of the velocity equation, viz--Reffs 5, 30). Finally,
the solution of a system of differential equations is
given, as a rule, in the form of a function of the

usually paid to the determi.ation of the velocity

in addition, present6d, in a figure (variation of concen-
