阅读说明：本技术 3,3,5-三甲基环己叉基双酚的制备方法 (Preparation method of 3,3,5-trimethylcyclohexylidene bisphenol ) 是由 J·范登艾恩德 E·施卢伊茨 K·海伦 M·特拉温 V·米歇尔 于 2019-08-15 设计创作，主要内容包括：本发明涉及3,3,5-三甲基环己叉基双酚(BP-TMC)的制备。特别地,本发明涉及在气态酸性催化剂存在下由3,3,5-三甲基环己酮(TMC-酮)和苯酚制备3,3,5-三甲基环己叉基双酚(BP-TMC)。优选连续进行制备。本发明的目的是当将气态酸性酸计量加入反应容器中的包含TMC-酮和苯酚的反应混合物中时,防止固体,特别是结晶的BP-TMC,更特别是结晶的BP-TMC-苯酚-加合物堵塞气态酸性酸的计量阀的出口。(The invention relates to the preparation of 3,3,5-trimethylcyclohexylidene bisphenol (BP-TMC). In particular, the present invention relates to the preparation of 3,3, 5-trimethylcyclohexylidenebisphenol (BP-TMC) from 3,3, 5-trimethylcyclohexanone (TMC-ketone) and phenol in the presence of a gaseous acidic catalyst. The preparation is preferably carried out continuously. The object of the present invention is to prevent solids, in particular crystalline BP-TMC, more in particular crystalline BP-TMC-phenol-adduct, from clogging the outlet of the metering valve for gaseous acidic acid when metering gaseous acidic acid into a reaction mixture comprising TMC-ketone and phenol in a reaction vessel.)
