(KO) 1,1-비스(4-하이드록시페닐)-3-알킬사이클로헥산, 이것의제조방법 및 이것으로부터 제조된 폴리카보네이트
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. The preferred 3- alkylphenols are those derived from cashew nut shell liquid. The products can be used to prepare polycarbonates.

(KO) 1,1-비스(4-하이드록시페닐)-3-펜타데실사이클로헥산과 같은 1,1-비스(4-하이드록시페닐)-3-알킬사이클로헥산은 3-알킬페놀을 포함하는 조성물을 대응하는 사이클로헥산올로 수소화하고, 사이클로헥산올을 사이클로헥산온으로 산화시키고, 사이클로헥산온을 산 촉매의 존재하에서 페놀과 접촉시킴으로써 제조된다. 바람직한 3-알킬페놀은 캐슈 너트 껍질액으로부터 유도된 화합물이다. 생성물은 폴리카보네이트를 제조하는데 사용될 수 있다.
