Synthesis method of dimorpholinyl diethyl ether

The invention belongs to the field of compound synthesis, and particularly relates to a synthesis process of dimorpholinyl diethyl ether. Comprising the following steps: 1, preparing a hydrotalcite-like nano copper-based catalyst: adopting copper nitrate, transition metal M nitrate, aluminum nitrate, a precipitant A and a precipitant B; 2, continuous synthesis of dimorpholinyl diethyl ether: firstly, loading a hydrotalcite-like nano-copper-based catalyst into a fixed bed reactor, and performing reduction activation on the hydrotalcite-like nano-copper-based catalyst by using hydrogen; preparing a raw material consisting of morpholine and diethylene glycol; the raw materials are pumped into a fixed bed reactor for reaction, so that reaction liquid containing the dimorpholinyl diethyl ether is obtained. The problems of low raw material conversion rate, poor product selectivity, short catalyst life and the like in the prior art are solved. 本发明属于化合物合成领域，具体涉及一种双吗啉基二乙基醚的合成工艺；包括以下过程：一、制备类水滑石纳米铜基催化剂：包括采用硝酸铜、过渡金属M硝酸盐、
