丙酮-环已烷-水液液平衡数据的测定与关联

摘要

为获取丙酮(1)-环己烷(2)-水(3)三元液液平衡基础数据,采用浊点法测定了该体系25℃下LLE数据,经NRTL方程关联,在σ都取0.2时,A12、A21,A13、A31、A23和A32分别为559、-148、177、282、2902和2772.%To obtain the liquid - liquid equilibrium data for acetone (1) - cyclohexane (2 ) - water ( 3), turbidity point titration is adopted to measure the LLE. Data at the temperature of 25°C. Binary interaction parameters of NRTL are regressed when a is 0.2, and A12, A21, A13, A31, A23 and A32 in SI unit are respectively 559, -148, 177, 282, 2902 and 2772.
