Description:    Cooling of polymer granules and strands in air and water was examined. The greatest effect of a turbulence of air flow on the cooling rate of granules was revealed in the starting period. An analysis of the cooling of granules in water demonstrated that the rate of heat transfer from a volume of thermoplastic material to its surface was a rate-limiting step and, thus, an effect of turbulization of a water flow on the cooling was negligible. We showed that it would be appropriate to install partitions destroying a heated boundary layer of water for intensifying process in a cooling bath since an actual cooling of the strands in the water bath longer corresponds to the case when water moves together with strand.

Description:    The effect of temperature factor on the efficiency of absorption of fluorine- and chlorine gas by a chemical absorbent, marble chips of a grade CA-MC, was researched. The degree of absorption of fluoride compounds at room temperature was 91%. The degree of recovery of total chlorine was 47.3%, that is because the low reactivity of the absorbent and an increase in an amount of Cl 2 in gases due to displacement of it by the fluorides from formed CaCl 2 . Calculation of thermodynamic characteristics of the processes showed that the equilibrium constant for the reaction of chlorine with CaCO 3 increased with a temperature growth, which proved larger intensity of the chlorine absorption by the hot absorbent. According to the suggested method, the gases containing chlorine fluorides successively passed through three distinct temperature zone of calcium carbonate: 230–600°C, 25–35°C and 300–600°C. In this case, the degree of recovery of fluorine compounds was 99%, and 98% of elemental chlorine was absorbed. Content Type Journal Article Pages 526-532 DOI 10.1134/S1070427211030347 Authors O. B.

Description:    Method of isothermal saturation in ampules was used to study the solubility of fullerenol in distilled water in the temperature range 20–80°C and to determine the composition of its equilibrium crystal hydrates. The pycnometric technique was employed to examine how the density depends of the concentration of fullerenol solutions and the average molar and partial molar volumes of the components in solution at 25°C was calculated. The method of refractometry was used to study the dependence of the refractive index on the concentration of fullerenol solutions and the specific refraction of the solutions was calculated.
