| Abstract: | 2,2’-ethylene-bis(4,6 di-tert-butyl-benzene phenol) was synthesized from 2,4-di-tert-butyl-benzene phenol and acetaldehyde.The effort of all factors on the reaction including the catalyzer,the mixture ratio of 2,4-di-tert-butyl-benzene phenol and acetaldehyde,reaction time as well as reaction temperature.The results indicate that the optimal mol-ratio n(2,4-di-tert-butyl-benzene phenol) : n(acetaldehyde)=2∶1.2,the optimal reaction is 5.5h,the optimal temperature is 91~93℃.The product was identified by IR. |
