Spontaneous clusterization of thioalcohols starts at length of a hydrocarbon radical of 14-15 atoms of carbon, amines - at 18-19, cis-monoenic acids - at 17-19, that answers experiment. The "Simple" method of an estimation of Enthalpy, entIalpy and Gibbs energy of clusterization SAC reproduces well parameters got earlier from the additive schemes and also experimental parameters. Balance a liquid-vapor in systems CO2 - EG, СО2 - DEG, СО2 - TEG and СО2 - N-MP at the high pressure (Т = 0-50 °С) has been investigated. The volumetric behavior of an equilibrium liquid phase in system CO2 - N- MP (Т = 0-30 °С) has been experimentally researched. Stratification in a liquid phase of system CO2-g-БЛ at temperatures above critical. Equation for calculation partial molar heats of dissolution of СО2 was deduced. Factors of activity, superfluous Gibbs energy, entalpys, differential molar heats of dissolution and mixing СО2 were calculated activity.
