摘要: |
应用硫酸氢钾催化肉桂酸与正丙醇的酯化反应合成肉桂酸正丙酯。硫酸氢钾具有较高的催化活性,可以快速地合成肉桂酸正丙酯,反应的最佳条件为:肉桂酸、正丙醇、硫酸氢钾的摩尔比=1:7.5:0.55,反应时间4h,所得肉桂酸正丙酯的产率为96.1%。该催化剂用量少,易于回收,并且可以重复使用。 |

Abstract: |
Normal propyl cinnamylate was synthesized by the esterification of normal propyl alcohol with cinnamic acid in the presence of potassium bisulfate monohydrate.The results obtained showed that the potassium bisulfate monohydrate consisted of a fairly high catalytic activity of the esterification reaction.The effects of cinnamic acid and normal propyl alcohol mol ar ratio, the amount of potassium bisulfate monohydrate catalyst applied, and the time of reaction on the yield of normal propyl alcohol and catalysis activity of catalysts reused have been surveyed.In the chemical reaction of the typical condition, the ester yield reached 96.1% (the mol ar ratio of cinnamic acid/normal propyl alcohol/potassium bisulfate=1:7.5:0.55, refluring 4h).Bisulfate monohydrate catalyst can be easily recovered and reused. |
