Abstract

The prodn. of bisphenols comprises reacting a phenol contg. >=1 reactive H and cpd(s) of formula or (I) where R and R1 are H, alkyl or aryl; X is acyloxy; Y is alkoxy, aryloxy or as X; Z is R2R3C(COO)2, where R2 and R3 are as R and R1; n is 3-9; and m = (n-1) in the presence of an acidic condensing agent. Also claimed are the prodn of Bisphenol A from phenol and 2,2-diacetoxypropane in the presence of HCl at 20-50 degrees C and the prodn of the Bisphenol C from phenol and cyclohexenyl acetate in the presence of HCl at 30-50 degrees C. Very pure bisphenols are produced, contaminants being removed by washing with CH2Cl2.
