一种5-甲基-5-己烯酸乙酯的制备方法
摘要：
本发明涉及一种5-甲基-5-己烯酸乙酯的制备方法，以丙烯酸乙酯为原料，其与异丁烯在催化剂存在下发生加成反应生成5-甲基-5-己烯酸乙酯，特别是，所述催化剂为无水四氯化锡，丙烯酸乙酯与异丁烯的投料摩尔比为1：2～3，催化剂用量为丙烯酸乙酯质量的0.8％～1.5％。该方法收率在50％以上，生产5-甲基-5-己烯酸乙酯的成本较低。
摘要（英）：

The invention relates to a method for making 5-methyl-5-ethyl hexenoate. The method uses ethyl acrylate as a raw material, and the 5-methyl-5-ethyl hexenoate is obtained by addition reaction of the ethyl acrylate and isobutene under the presence of a catalyst, wherein the catalyst is anhydrous stannic chloride particularly, the feeding molar ratio of the ethyl acrylate to the isobutene is 1 to 2-3, and the catalyst accounts for 0.8 to 1.5 percent of the mass of the ethyl acrylate. The method has more than 50 percent of yield and has low cost for producing the 5-methyl-5-ethyl hexenoate.
