高圧下における水溶液系の相平衡と溶解度

抄録

The properties of aqueous mixtures containing organic liquids vary uniquely with composition in a manner depending on the nature of the solute molecules; the behavior is responsible for producing several kinds of phase separation and has received much attention in solution chemistry. Information on the phase equilibria of the aqueous mixtures is particularly important in development of industrial separation techniques such as distillation, absorption, extraction, crytallization etc. The purpose of this review is to describe briefly the phase equilibria under high pressure for some cases of aqueous binary and ternary mixtures with organic liquids. Comments are given about the effects of temperature and pressure on the critical solution properties, solubilites, and ability of extraction.
