Experimental data have been obtained in the temperature range from 93.15 to 283.15K at pressures from that of saturated vapors of pure ethane to 4MPa. Equations that approximate the temperature, pressure and concentration dependences of a2 and σ are suggested. The concentration dependence of the surface tension is described in the framework of models of an ideal and a regular solution. The relative adsorption has been calculated Доп.точки доступа: Kaverin, A. M.; Каверин Алексей Михайлович; Khotienkova, M. N.; Байдаков Владимир Георгиевич
