Title
(EN) 1,1-bis(4-hydroxyphenyl)-3-alkylcyclohexanes, method for their preparation and polycarbonates prepared therefrom
(ZH) 1,1-双(4-羟苯基)-3-烷基环己烷、其制备方法和由其制备的聚碳酸酯
Abstract
(EN) 1,1-Bis(4-hydroxyphenyl)-3-alkylcyclohexanes, as illustrated by 1,1-bis(4-hydroxyphenyl)-3-pentadecylcyclohexane, are prepared by hydrogenating a composition comprising 3-alkylphenols to the corresponding cyclohexanol, oxidizing the cyclohexanol to a cyclohexanone and contacting the cyclohexanone with phenol in the presence of an acidic catalyst.
(ZH)

通过氢化包括3-烷基酚的组合物得到相应的环己醇;氧化环己醇得到相应的环己酮;和在酸性催化剂存在下接触环己酮与苯酚制备1,1-双(4-羟苯基)-3-烷基环己烷,例如1,1-双(4-羟苯基)-3-十五烷基环己烷。
