| titleOfInvention | Method for preparing alkyl levulinate by regulating water content |
| abstract | The invention discloses a method for preparing alkyl levulinate by regulating water content, which comprises the following steps: mixing at least furfuryl alcohol, alkyl alcohol and an acidic catalyst to form a reaction system, and performing the reaction under the conditions of continuous stirring and condensation and reflux, and regulating the reaction system The content of water is such that the ratio of the amount of furfuryl alcohol and the amount of water is 1: 0.1 to 5, and after post-processing, the alkyl levulinate is obtained; the structural formula of the alkyl levulinate is: wherein R is selected from any one of -CH 3 , -C 2 H 5 , -C 3 H 7 , -C 4 H 9 , -C 5 H 11 . Compared with the prior art, in the present invention, the alkyl levulinate is prepared by controlling the water content, the process is simple and feasible, the conditions are mild, the cost is low, the by-products are few, and the yield is up to 99.8%, which solves the problem in the current synthesis method. The problem of low yield of alkyl levulinate. |
