| Abstract: | The synthesis of dibutyl sebacate with butyl alcohol and sebacic acid as reactants and amidosulphonic acid as catalyst had been studied.The influent actors of reaction were investigated.The results showed that the appropriate conditions should be:weight of catalyst was 0 5g(weight of sebacic acid if 0.05 mol);molar ratio of butyl alcohol to sebacic acid was 3:1;reaction time was 1 5h;the taking water reagent!(Toluene)was 5 mL.The yield of dibutyl sebacate was about 99 0%. |
