Definition of parameters phase equilibria and identification of phases of system hydrocarbon Water on the basis of calorimetric measurements

A new calorimetric method and the results of determination of binary systems phase equilibria having a region of phase stratification on the basis of calorimetric measurements are described in this paper. Isochoric heat capacity temperature dependence of binary system of hydrocarbon-water has been studied by the method of high-temperature adiabatic calorimeter. Parameters of the phase stratification region have been determined on the basis of revealed peculiarities of this dependence at phase transitions liquid-liquid and liquid-vapour and phase diagram have been made.     

PC-based automated setup for measuring the isochoric heat capacity of liquids

A setup formeasuring the isochoric heat capacity of liquids and gases and its automation method based on a Keithley 2000 digital multimeter and a personal computer are described. The program development in the Labview 7 environment is considered. The experimental measurement method itself is also briefly described.
