摘 要:以对甲苯磺酸为催化剂合成了山梨酸异丙酯,讨论了催化合成的条件,确定了反应的最佳条件为山梨酸:异丙醇=1:4(mol/L),催化剂3mmol,产率达78.4%。研究了新型防腐剂山梨酸异丙酯对常见霉菌的抑制效果,并探讨了其在酱油、食醋等调味品中的防腐保鲜效果。Isopropyl sorbate was synthesized with sorbic acid and isopropanol as raw materials and p-toluenesulfonic acid as catalyst. The synthesis conditions were discussed. And the optimal conditions were determined as follows: the molar ratio of sorbic acid to isopropanol was 1:4, and the amount of catalyst was 3 retool. With above conditions, the yield of isopropyl sorbate was 78.4%. Furthermore, the inhibitory effects of isopropyl sorbate on familiar moulds were studied. The preservative activity and the fresh-keeping effect of isopropyl sorbate in condiments, such as soy sauce and vinegar, were also discussed.
