硅胶载体酸催化下富马酸二丁酯的合成

Study on the synthesis of dibutyl fumarate using carrier acid as catalyst

以顺酐和丁醇为原料，采用硅胶载体酸为催化剂合成了富马酸二丁酯；讨论了载体酸催化剂的用量、原料配比、投料方式。

The synthesis of dibutyl fumarate from maleic angyclrine and butanol,using silica gel carrier acid as catalyst is reported,the conditions of reaction by changing several factor:burden ratio,feeding meaning,temprature(℃),time(h),solvents bulk(mL),catalysts bulk(mL) etc.are mainly discussed.Purity can be beyond 97% and yields over 95%.
