1,1-bis(4-hydroxyphenyl)-3-alkylcyclohexanes, method for their preparation and polycarbonates prepared therefrom |
| abstract |
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. |
