Energetik, 12, 10-11, D 1955
According to the circulars of the Technical Administration
of the Ministry of Electric Power Stations 4/T52 and
T1/54, the firing of high pressure boilers has to be done
In such a way, that the temperature differences between
the hotte�t and 8oldest parts of the boiler drums do not
exceed 30u to 50 C. The authors present a simplified
method of measuring drum temperatures. Three drawings.

TITLE: Some properties of aqueous solutions of NH4H2PQ~ and NU~~P04
SOURCES Zhurnal neorganichaskoy khimii, v. 12, no. 1, 196?, 62-67
TOPIC TAGS: ammonima phosphate, deuterium compound, deuterium oxide
ABSTRACT: The solubility of NH4H2PO4 (ADP) and N4~~P% (D-ADP) and the density,
refractive index and conductance of their aqueous solutions ware studied in order
to make use of the corresponding concentration and temperature relationships for the
control of the crystallization process. The doutoratod compound was prepared by
successive crystallizations of ADP from heavy water. The solubility of ADP and
D-ADP was found to be linearly related to the temperature: a = 26.21 + 0.4463 t, and
the solubility of D-ADP In U~O surpasses that of ADP in H20 by about 8%. A plot of
,the density of the ADP and D-ADP solutions versus their concentration gave a linear
dependence. The refractive index data are described by the linear relationships
XADP = 1.3309 + 0.00138c,
ND-ADP= 1.3285 +*0.001380. '**

V At all the concentrations studied, the specific conductance x of AL? a-d D-Z?
solutions changed linearly with temperature (between 25 and 700C). Because of the
lower mobility oj* D+ ions as compared to H+t the conductance of saturated D-AD?
solutions is much less than that of AD? solutions. Using the relationships esta"o-
lished in the study, the authors grow homogeneous single crystals of ADP and D-ADP

T.b-- investigation 'was concerned with detg the laws
governing the reaction between nickel carbonyl and
,=1 1-.'acetylen-en. Mcpts were carried out with
j
mthyl-, butyl-, and vinyl acetylene, and diprop'argyl.
It was found that the reactivity of the 2 reagents
toward each other decreases, as the mol wt of the
acetylene hydrocarbon increases, so that the temp
required for reaction increases with the mol vt.
Addn of nickel carbonyl takes place according to
Markovaikov's rule, i.e., the single reactior prod-
iict, will always be a deriv of cK-substituted
acrylic acid, accorging to the formula 4RCrCH+Wi(CO)4
+RIOE+2HClu4M2= O-COOR1+NiCl2+H2. Dipropargyl,
Im contrast to the other compds, does not react well,
giving a small yield of an eater of a monocarbox~f-
lic acid which contains an ethylene bond. It was
not studied further. Presented by Acad A. N. Nes-
meyanov.

TEXT: The authors found already previously that in the reaction of some
alkyl acetylenes with nickel tetracarbonyl in alcoholic media, a-alkyl
acrylates form by the Markovnikov rule. Therefore, in the reaction of
vinyl acetylene with N'(CO)4 in alcoholic media the formation of a-vinyl
acrylates was to be expected: 4CH2 = CH -C -CII + Hi(CO)4 + 2HCl

published after this paper had been finished, the structure of a-(4-

final product of the above reaction. This error is proven by the identity

I TEXT: The processes of the separate and combined radiation pol~merizationf
of tetrafluorathylene and trifluorchlorethylene have been investigated with
the aim of el`,~minating some of the deficiencies in existing methods cf
fluoro-olefine polymerization. It has been found that tetrafluorethyiene
and trifluorchlorethylene can easily be polymerized under various
temperature conditions and mediums with comparatively low radiation
intensities. The resulting polymers have a high degree of purity. The
possibility o:' producing various fluoro-copolymers by radiation is
demonstrated. Both radiation polymerization and radiation vulcanization
might be carried out in the case of fluor-contaiining rubbere. [Abstracterl~s

ABSTRACT: Tho effect of ga=a-irradiation by Co6O on hexafluoropropylene was
investigated within a temperature range of 77-303K in the liquid and solid phas**
of the monomez, and also at the point of phase transition. A dosage of 600
rad/sec. was usad. It was shown that polymerization of hexafluoropropylano in
the liquid and solid phases at various temperatures and at identical dosage did
not produce sharp changes in the rate of the process. The rate did not change
when the polymerization was conducted at the point of phase transition. It war,
found that the index of the polymerization rate as related to the radiation inten-
sity changes with temperature and is equal to I at 298K to 0.5-0.6 at 195X, and to
0.4 at 77K. T4e change in the aotivation energy In relation to the polymerization

ABSTRACT., The re,diation polymerization trifluorochloroethylone (TFCIE) was studied at
different irradiation dosages over a wide temperature range. There Is no
polymerization at -1960C; at -78'C the yield of a low molecular weight product is onv
20 molec/100ev; Jm the range from -20 to 4600C the energy of activation of the reaction
changes from 3-1 to -6.8. As radiation dosage increased, the totaporaturo at which the
maximum procons rate wan attained also increased. As tomporaturo is increased from
10-500C, the polinnerization rate and polymer molecular weight increased; at higher
temperatures, tho rate and molecular weight decrease. Reaction mechanisms are
discussed. Solution polymerization of TFC19 was studied in carbon tetrachloride,
