以山梨酸和正丁醇为原料,硫酸氢钠为催化剂高效合成了标题化合物,考察了影响收率的各种因素,确定最佳反应条件为:n(山梨酸)∶n(正丁醇)=1∶4;催化剂用量为山梨酸质量的6%,反应温度120℃,反应4 h,收率可达90%以上。结果表明,硫酸氢钠具有催化活性好、可重复利用、环境污染小的特点,是合成标题化合物的良好催化剂。 The title compound was synthesized using sorbic acid and n - butanol as raw materials and sodium bisulfate as catalyst. The factors influencing the yield were investigated. The optimal reaction conditions were n (sorbic acid): n (n - butanol) = 1: 4; the amount of catalyst is 6% of sorbic acid, the reaction temperature is 120 ℃, the reaction for 4 h, the yield can reach more than 90%. The results show that sodium bisulfate has the characteristics of good catalytic activity, reusability and small environmental pollution, and is a good catalyst for the synthesis of the title compound.
