Abstract:
A process for production of 1,3-di(2-p-hydroxyphenyl-2-propyl)benzene which comprises:reacting 1,3-di(2-hydroxy-2-propyl)benzene with phenol in an amount of 4-6 times in mols the amount of the 1,3-di(2-hydroxy-2-propyl)benzene in the presence of an acid catalyst at a temperature of 10-55.degree. C. thereby crystallizing adducts formed of phenol and the resulting 1,3-di(2-p-hydroxyphenyl-2-propyl)benzene so that the reaction is effected in a slurry, and thenrecovering 1,3-di(2-p-hydroxyphenyl-2-propyl)benzene from the adduct.
