Abstract

PURPOSE: To obtain dihydroxydiphenylmethane useful as a raw material for an epoxy resin of low viscosity readily, by decoloring under heating a colored dihydroxydiphenylmethane solution in an organic solvent at a low temperature with sodium boron hydride.
CONSTITUTION: A colored dihydroxydiphenylmethane solution in an organic solvent, e.g. benzene or epichlorophyrin, is heat-treated at 0W150°C, preferably at 0W100°C, with sodium boron hydride in an amount of 0.001W1wt% based on the dihydroxydiphenylmethane, usually for 1W2hr, to give a decolored dihydroxydiphenylmethane. The dihydroxydiphenylmethane is obtained by the reaction of phenol with formaldehyde.
