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.

(FR)
L'invention concerne des 1,1-Bis(4-hydroxyphenyl)-3-alkylcyclohexanes, tels qu'un 1,1-bis(4-hydroxyphenyl)-3-pentadecylcyclohexane, préparés par hydrogénation d'une composition comprenant 3-alkylphenols en cyclohexanol correspondant, à oxyder le cyclohexanol en un cyclohexanone, et à mettre en contact le cyclohexanone avec un phénol en présence d'un catalyseur acide. Les 3-alkylphenols préférés sont dérivés d'huile de cajou. On peut utiliser ces produits pour préparer des polycarbonates.
