| Abstract: | Dibutyl succinate is prepared from succinate acid with n-butanol as reactant,phosphotungstic acid as catalyst,toluene as azeotropic agent.The optimum technical condions were investigated in detail by Uniform design,which includs effects of catalyst,mole ratio of reactants,quantity of azeotropic agent,reaction temperature and time on yield.The results indicate that 99.47% yield could be obtained with the following optimal reaction conditions:the mole ratio of n-butanol to succinate acid 3.0:1,the mount of catalyst 1.1% by mass of acid,the mount of azeotropic agent 22% by total mass and the reaction time 2 h. |
