PROCESS FOR PREPARING TETRAKIS(3-(3,5-DI-tert-BUTYL-4-HYDROXYPHENYL)PROPIONYLOXYMETHYL)METHANE |
| abstract |
A process for preparing tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionyloxymethyl)methane by conducting an ester-exchange reaction of an alkyl 3-(3,5-di-tert-butyi-4-hydroxyphenyl)propionate with pentaerythritol in the presence of a basic catalyst, which comprises conducting the reaction in the presence of an alkyl 3-(3-tert-butyl-4-hydroxyphenyl)propionate. This process ensures preparation of tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)-propionyloxymethyl)-methane with good reproducibility in a high yield and as fine particles having good properties and no coloration. |
