Process for producing ethylene carbonate

Abstract

The invention relates to a method for producing ethylene carbonate and mainly solves the problem of low activity of a heterogeneous catalyst in the prior art. The problem is better solved by means ofthe technical scheme as follows: the method comprises the following steps: ethylene oxide and carbon dioxide are contacted with a catalyst under the reaction condition, wherein the catalyst is prepared from 1wt%-30wt% of alkali metal on the basis of M2O and 70wt%-99wt% of aluminum phosphorus oxide carriers APO. The method can be applied to industrial production of preparation of ethylene carbonatefrom ethylene oxide and carbon dioxide.

Description

technical field

[0001] The present invention relates to a kind of method of producing ethylene carbonate, especially a kind of method of producing ethylene carbonate with ethylene oxide and carbon dioxide. Background technique

[0002] Ethylene carbonate is an excellent solvent and fine chemical intermediate, and a potential basic raw material for organic chemical industry. At the same time, CO 2 Is a greenhouse gas, how to effectively fix has become one of the most challenging issues in this century. And through ethylene oxide and CO 2 Reactive synthesis of ethylene carbonate is one of the good fixation methods. With the recent increasing attention to the co-production of dimethyl carbonate and ethylene glycol using ethylene carbonate as a raw material, the fixation of CO by cyclic carbonate 2 approach has also received increasing attention.

[0003] The heterogeneous catalysts reported so far for the production of cyclic carbonates include MgO, MgO / Al 2 o 3 And Cs / K...
