Abstract
Process for recovering a purified 2,2- (4,4'-dihydroxydiphenyl) propane from its crude reaction product obtained by the condensation of phenol with a compound selected from the group consisting of propadiene, propyne and mixtures thereof, whose procedure includes the operations of (1) separating the most volatile materials from 2,2- (4,4 -'-dihydroxydiphenyl) propane (2) distill in vacuo: 2,2- (4,4'-dihydroxydiphenyl) propane of less volatile materials included therein and (3) separating distilled 2,2- (4,4'-dihydroxydiphenyl) propane from its impurities with a solvent selected from the group consisting of benzene, toluene, xylene and chlorinated aliphatic hydrocarbon solvent having a boiling point of less than about 130º C and the ability to dissolve at room temperature at least 30 times the amount of impurities contained in crude 2,2- (4,4'-dihydroxydiphenyl) propane as of 2,2- (4,4'-dihydroxydiphenyl) propane, in virtu d of which substantially pure 2,2- (4,4'-dihydroxydiphenyl) propane and a solvent solution of separate impurities are produced.
