Abstract
STUDING OF POLITHERMAL SOLUBILITY OF TRIS-ACETYLACETONAT CHROME (III) AND COBALT (III) IN WATER-METHANOL SOLVENTSVladislav A. Fedorov, Nikolay V. Vologdin, Pavel V. FabinskiySiberian state technological university 660049, Krasnoyarsk, pr. Mira, 82 The data of solubility of tris-acetylacetonats cobalt (III) and chrome (III) in water and water-methanol solutions in a wide range of temperature and concentration of alcohol is presented. Statistical processing of the received data is spent. Thermodynamics parameters of process dissolution are calculated. Оn dependences solubility inversion point corresponding to change of the mechanism of gidration at evolution from structure of water to structure of alcoholic solution is found out on concentration. Dependences lgS-Cаl are almost parallel to an axis of abscises in the field of high concentration > 0.8-0.9 mole fraction.
