실험 절차

In a method of making 1,1-bis-(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane in the form of an adduct with phenol wherein 3,3,5-trimethylcyclohexanone is reacted with phenol in the presence of an acid condensation catalyst and an alkane thiol of the formula R1R2CHSH where R1 is an alkyl, aryl or alkaryl group having from 1 to about 20 carbon atoms and R2 is H or R1, to obtain a reaction mixture including 1,1-bis-(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane in the form of an adduct with phenol, the improvement comprising adding water to said reaction mixture to obtain a slurry, filtering said slurry to obtain 1,1-bis-(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane phenol adduct as a solid, and a filtrate having an organic phase and an aqueous phase, recovering said organic phase, contacting said organic phase with an acid condensation catalyst at a temperature of about 0° C. to about 150° C., and adding phenol and 3,3,5-trimethylcyclohexanone to the organic phase so treated to make additional 1,1-bis-(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane.
