Abstract

PURPOSE: To prepare a crystallized bis(3,5-dihydroxymethyl-4-hydroxyphenyl) alkane having high quality and useful as a raw material of epoxy resins, etc., by reacting a bis(4-hydroxy-phenyl)alkane with formaldehyde in the presence of a basic catalyst under specific conditions and thereafter precipitating the product with acid.
CONSTITUTION: (A) 1mol of a bis(4-hydroxyphenyl)alkane selected from bis (4-hydroxyphenyl)methane, 1, 1-bis(4-hydroxyphenyl)ethane and 2,2-bis(4-hydroxyphenyl)propane is reacted with (B) 3.7W4.3mol of formaldehyde in an aqueous solution at 0W55°C, preferably at 30W50°C in the presence of a strong base catalyst containing 1.6W2.5gram atom of an alkali metal, e.g. sodium hydroxide, etc. The product is precipitated with a diluted hydrochloric acid, etc. at 0W40°C to give the desired compound.
USE: Additives for novolak-phenol resins, curing agents for epoxy resins, etc.
