PROCESS FOR PRODUCING 1,1-BIS(4-HYDROXYPHENYL)-3,3,5-TRIMETHYLCYCLOHEXANE |
摘要 |
A process for producing 1,1-bis(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane (BPTMC) by reacting phenol with 3,3,5-trimethylcyclohexanone (TMC) in the presence of an acid catalyst, characterized by initiating the reaction of phenol with TMC in the presence of the acid catalyst in a slurry comprising crystals of a phenol adduct of BPTMC and hydrous phenol and subsequently conducting the reaction in the slurry. By the process, BPTMC can be industrially produced stably with high selectivity in high yield.
