Abstract:β-(3,5-Diterbutyl-4-hydroxyphenyl) propionyl chloride is synthesized with 3,5-methyl propionate as raw material via hydrolytic reaction and replacement reaction,and the replacement reaction conditions were explored. The optimal reaction conditions were as follows:chloroform was used as the reaction solvent,3,5-propionyl acid 0.02 mol,sulphoxide diloride 0.054 mol,the reaction temperature 50℃ and the reaction time 5 h. Under these conditions,the yield of product was 98.9%. |
