摘要：

We report here a new procedure to purify nonionic amphiphiles (alkyl polyglycol ethers, CiEj). The method utilizes the well-known phase behavior of ternary systems of water, oil, and nonionic amphiphiles to extract simultaneously water- and oil-soluble impurities. The three-phase extraction technique (denoted as 3PHEX) is easy to apply and demonstrated to yield reproducible miscibility gaps of binary water-nonionic amphiphile mixtures. The critical temperatures and compositions for amphiphiles of varying chain length, ranging from C6E3 to C12E6, are given. © 1991.
