air layer may also be neglectedj, and the basic consideration becomes that of the
horizontal temperature gradient at the ocean surfaces The average temperature of
an air layer dose not change appreciably when air mosses pass over any particular

ABSTRACT: The author developed a device, shown by figure 1,
for adjusting (lapping) the measuring surfaces of
micrometers having a measuring range of more than
100 mm. This device is used at the Gorlkiy avtoza-
vod (Gorlkiy Automobile Plant). A cast iron lap is
used having a hardness of 90-120 H with the follow-

ing chemical composition: 4% carl
n, 2.8% silicon,
0.7% manganese, 0.12% phosphorus, 0.2% chrome and
not more than 0.016% sulfur. The structure of the
lap must be graphitic, medium or fine-laminar the
metallic basis must have ferrite structure, p~rlite
inclusions must riot exceed 25%. For preliminary

TEXT: Basic methods of using organic reagents in hydrometallurgy are
3nalyzed. Organic reagents can be employed as solvents for extracting metals
frpm solid products (lixiviation) Euid from aqueous solutions (liquid extraction);
thd latter process in used more frequently. The following extracting agents are
uted: hydrocarbons and chlorine derivatives, oxyg6n-containing organic 5olvents
which do not contain saltforming groups, plain esters, alcohols. complex carbonic
acid esters, phosphorus- and nitrogen-containing extracting agents. Individual
examples are quoted of separating-out metals by lixiviation and extraction, and
the basic difficulties Df the process are mentioned. The other field of employing
organic reagents is the precipitation process. The advantages of organic preci-

pitating agents are given, individual examples are quoted of using same; the
possibility Is Indiceted of using organic reagents as precipitating agents. The
next fiel-I of using organIc reagents are ion-exchange processes ured for extract-
Ing metals from solutions with poor metal content, for refining valuable metal
solutions from impurities and for the selective separation of valuable metals.
Advantages and individual examples are mentioned of using ion-exchange processes.
Orgnnic reagents are employed as reducing agents to transfer the metal extracted
into lower valonces, and as coagulating agents. In the latter case organic
poly-electrolytes are used. Other fields of using organic reagents are also
mentioned; such as bacterial processes for performing oxidizing-reducing reac-
tions with the aid of bacteria, electrolytic processes, in studying the chemism
of hydrometallurgical processes. There are 106 references.

tant obtained from the mixture of industrial alcohols maintains the *xtraotabili-

the eztraotant causes thin stabilization of oztraotability, but the solution of
this qu*stion could be of Interest for the use of correspondent admixtures to
the single alkylpyrophosphates. rAborstory tests on the oxtractabllity of the

metals. The most convenient concentration is 5 - 10 % alkyl phosphoric aaids in
the solution of the extraotant. The extraction depends considerably on the can-
centration of the metal in the solution, I.e., the higher the concentration the
better is extraction (Table 1). Extractability of alkyl phosphoric wids obtained
from the total mixture- of industrial alcohols and from single fractions to com-

ABSTRACT: This is a study of' the composition of acid a.'Kylphos-
phates used in the extracl~ion of metals from aq,ieo,~s media,
and of the chemistrj of this process. Acid alk~ylphos-
phates are usually obtained in reaction of a1cclic:s with
P205; the reaction yield!3 various phosphoric a-id esters,
depending on the rat.-io c,!' the reagen's arid :c.-Allicris
of the reaction:

alcohols with P2 05 gave no neutral esters b"t only aciJ
esters in the form of a mixture of mono- and diesteru.
The yield of monoesters increased, and that or di-
esters decreased with the increase of the molar ratto of
alcohol to anhydride (rrom 2 to 6). The molar ratio 2:1
gave predominantly die-oters (67.7 to 90.5%); chiefly,
diallcylpyrophoaphate3. The metal extraction capacity
of the alkylphosphates wjs investigaj~d on solutions

with various cations (Fe + , TiIV, Zn , Cb) and anions
(CI-, NO-, SO 2-, PO 3-), and the content of extracted
3 4 1~
cations and anions in the alkylph03phate5 was Jetermir',ed
by quantitative analys1:3 and with the help of radio-
active isotopes. Apparatus B-2 and end-window co--;nter
MST-17 were used in the study. In the case cf' Fe (So.)

ratio and Fe3+ extracted in practically identical arlc_~nts
(about 52%) from acid as well as from rle3rly !-Iv, i'ra.'

solution3. The degree of extraction of SO~~ 2- Was
considerably higher from acid than from neutral so'L,-I-
tions. Most of the sulfate ion, however, was eliminated
on wanhing with water, whereas the iron cation remained
insoluble. Accordingly, che re-extraction from. the
organic phase gave 5 to 13 times more iron than sulfate
iona, These and other experimental data indicate thht
the extraction of metals with acid alkylphosphates has
an ionic character. It can also be assumed that acid
alkylphosphates can be used for metal. extraction fro-,
strongly acid as well as from weakly acid solutions.
