| Abstract: | A new composite solid acid SO42-/ZrO2-MoO3 was composed and used as a catalyst in the synthesis of fumaric acid dimethy. The factors affecting the reaction was inspected. Result indicated:Using solid acid SO42-/ZrO2-MoO3 as catalyst and taking Malay estolide and methanol as raw material,the best technological cond- itions of the synthesis of fumaric acid dimethylcomposing is:n(methanol)∶n(estolide)(mole of ratio)= 6∶1,catalyst do-sages are 1.5 %(general mass),reaction temperature:95～100 ℃,reaction time is 3 hours,and fumaric acid dimethy productivity amounts to 93 %. |
