The invention discloses a preparation method of ethyl 3-ethoxypropionate. The catalyst used in the method is a heteroatom modified Y-type molecular sieve catalyst. The steps of preparing the catalyst include the steps of pore expansion, organosilicon modification, loading of active components and auxiliary active components, and the like. The catalyst has the advantages of high raw material conversion rate, high product selectivity, effective suppression of by-products, long life and good stability, and mainly solves the need for deactivation treatment of catalysts in the prior art, serious three wastes, low production efficiency, polymerization blockage, and recovery. difficulties, etc. |
