盐效萃取是指盐加入到恒沸有机物水溶液中时，由于盐与溶剂分子的相互作用，引起溶液液-液相平衡的变化，即溶剂间分配系数的变化，从而达到分离的目的。
Salt effecting extraction refers to adding salt into the organic aqueous constant-boiling solution, and with the salt-solvent interactions the Liquid-Liquid Equilibria (LLE) in the solution will be changed, which means a variation of the distribution coefficient between solvents and lead to the separation.
对于环己酮-水体系而言，由于碳酸钾与水的相互作用远远大于环己酮与水的相互作用，因此，当碳酸钾加入到环己酮水溶液中时，由于碳酸钾的盐析效应，使环己酮-水-碳酸钾体系达到相平衡状态时所形成的有机相中含有少量水和极少量碳酸钾，盐水相中含有极少量的环己酮，从而实现环己酮-水恒沸物的低能耗分离。
When potassium carbonate is added into the cyclohexanone-water system, a cyclohexanone-water- potassium carbonate system can be found in the solution. Because the potassium carbonate-water interaction far surpasses the cyclohexanone-water interaction, when the cyclohexanone-water- potassium carbonate system reaches a state of equilibrium, there will be little water and trace amount of potassium carbonate left in the organic phase and trace amount of cyclohexanone in the salt-water phase, which provides an energy-saving separation technology for the cyclohexanone-water azeotrope.
