Abstract
Dibutyl succinate is synthesized from succinic acid and n butyl alcohol with p toluene sulfonic acid as catalyst.All factors that can influence the esterification ratio are studied.The result shows that the best reaction condition is:based on 0.05 mol succinic acid,molar ratio of n butyl alcohol to succinic acid is 2.2,mass of catalyst 0.1g the taking water reagent 5ml,reaction time 50min.The esterification ratio is over 98%.
