Study on Synthesis of Preservative Benzyl Methyl Fumarate

Using maleic anhydride, benzyl alcohol and methanol as raw materials, a new preservative benzyl methyl fumarate containing α, β-unsaturated carbonyl structure was prepared. Based on the single factor experiment, the results of orthogonal test showed that the optimal conditions for the reaction was 4 h time, temperature at 65 °C, and with molar ratio of fumarate acid to methanol at 1:5. The production rate was 65.53%.
