Abstract
PURPOSE: To obtain the title compound suitable for a raw material for an epoxy resin, having a specific composition, in high yield, by the reaction of phenol with HCHO in a specific ratio in the presence of oxalic acid in an inert atmosphere, and then by removing the excessive phenol through distillation.
CONSTITUTION: Phenol (P) is reacted with formaldehyde (F) in the molar ratio range of F to P of 0.02W0.04:1, in the presence of oxalic acid in an amount of 0.01W5wt% based on P, in an inert atmosphere, at 50W110°C, and the excessive P is distilled out of the reaction product to obtain the title compound containing 10W 25wt% of 2,2'-dihydroxydiphenylmethane, 40W60wt% of 2,4-dihydroxydiphenylmethane, and 25W40wt% of 4,4'-dihydroxydiphenylmethane, in high yield, with controlled contents unreacted P and high-degree condensate.
