A bis (2-dialkylaminoethyl) ether synthesizing method is disclosed, which includes steps of: 1) synthesizing: wherein N,N-dialkylethanolamine, N,N-dialkylamine and ethyne are mixed at a mole ratio of 4:3:1-2:1:1 as a raw material; and the raw material, catalyst and solvent are added in a high-pressure clave for reaction in a sealed condition; a weight of catalyst accounts for 2.0%-10.5% of the total weight of the raw material; a reaction temperature is 50-120° C. and the reaction time is 3-7 hours; the clave is then opened after reaction and a filtrate is collected by filtering the reaction mixture; and 2) separating: wherein the filtrate obtained in the step 1) is rectified to obtain the bis (2-dialkylaminoethyl) ether as a product. The synthetic method of the bis (2-dialkylaminoethyl) ether in the present invention has many characteristics, such as simple process, high atomic economy, etc.
