Abstract

1,274,798. Purification of 2,2-di-(4-hydroxyphenyl) propane. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 14 Dec., 1970 [15 Dec., 1969 (2)], No. 59228/70. Heading C2C. A process for purifying 2,2-di-(4-hydroxyphenyl) propane comprises cooling a single phase liquid mixture of 2,2-di-(4-hydroxyphenyl) propane, phenol and from 3-98% by weight, based on the weight of phenol, of water to a temperature at which an equimolar adduct of 2,2-di-(4-hydroxyphenyl) propane and phenol crystallizes, separating the crystals so formed and removing the phenol component therefrom to yield purified 2,2-di-(4-hydroxyphenyl) propane.
