Title: The Catalytic Synthesis of Dibutyl Maleate by SO_4~(2-)/TiO_2/La~(3+) Rare earth Solid Superacid
Abstract: The synthesis of dibutyl maleate with n butanol and maleic acid as reactants and rare earth solid superacid SO 4 2- /TiO 2/La 3+ as catalyst was studied.The influence factors of reaction were investigated.The results showed that the appropriate conditions were as follows:mass of catalyst 1 0 g (based on 0.1 mole maleic acid),n(n butanol)∶n(maleic acid)=4 0∶1,reaction time 3 0 h,water carrying reagent (toluene) 15 mL.The yield of dibutyl maleate was about 97 4%.
