METHOD FOR SYNTHESIZING POLYOXYMETHYLENE DIMETHYL ETHERS BY IONIC LIQUID CATALYSIS |
摘要 |
The present invention discloses a method for synthesizing polyoxymethylene dimethyl ethers by ionic liquid catalysis. The method comprises synthesizing polyoxymethylene dimethyl ethers by using a functional acidic ionic liquid as catalyst and using methylal and trioxymethylene as reactant under a relative mild reaction condition. The invention has advantages of high catalyst activity and reaction conversion, simple reaction process, high operationability and controllability, as well as good product distribution and high raw material utilization ratio.
