PURPOSE:To obtain a bis(hydroxybenzyl)benzene compound useful e.g. as a curing agent for polyester, epoxy resin, etc., in high purity and yield by reacting a phenolic compound with an aralkyl compound in the presence of an acid catalyst, removing the acid catalyst from the product and distilling the product in vacuum. CONSTITUTION:This bis(hydroxybenzyl)benzene compound of formula III can be produced by reacting phenol or cresol with an aralkyl compound of formula I (X is a halogen, OH or a 1-4C alkoxy) (e.g. alpha,alpha-dichloroxylene) in the presence of an acid catalyst such as hydrochloric acid or formic acid to obtain a phenolic aralkyl resin composition of formula II (R is H or methyl; (n) is 0-50), removing or inactivating the acid catalyst in the composition and purifying the composition by vacuum distillation. |
