Method for jointly producing glycol ether and ethylene glycol diethyl ether by adopting ethylene glycol as raw material

The invention discloses a method for jointly producing glycol ether and ethylene glycol diethyl ether by adopting ethylene glycol as a raw material and belongs to the technical fields of fine chemicals and catalysis. According to the method, the ethylene glycol and ethyl alcohol or ethylene glycol and diethyl ether or ethylene glycol and ethyl alcohol as well as a diethyl ether mixture are adopted as raw materials, one or more than one of substances adopting H , Al , B as positive ions and adopting SO4 , NO3 , NO2 , PO4 and X (X=F, Cl, Br and I) as negative ions is adopted as a modifier and a substance for modifying a molecular sieve or a metallic oxide is adopted as a catalyst to synthetize the glycol ether and the ethylene glycol diethyl ether. The method has the advantages that the problem of reactant generating of ethylene glycol per se in the reaction of the ethylene glycol and the ethyl alcohol is solved; the glycol ether and the ethylene glycol diethyl ether can be jointly produced at the same time; the generating proportion of the glycol ether and the ethylene glycol diethyl ether can be controlled within a certain range.
