Abstract

The invention provides a synthesis method for synthesizing an oxetane derivative by a microreactor. The synthesis method comprises: delivering 3-ethyl-3-hydroxymethyloxetane, a raw material Ha, a catalyst, and an alkali into a microreactor, and performing an etherification reaction so as to obtain an etherification product system, the raw material Ha having a general formula of R-(X)n, and X being a halogen; and separating the etherification product system so as to obtain the oxetane derivative. The microreactor is used for greatly improving the mass and heat transfer properties of the reaction system, reducing the reaction time, improving the production efficiency, increasing the yield of the product, achieving the continuity and automation of the process, and improving the safety of the process. In addition, the reaction device required by the described synthesis process requires has a small size, requires less manpower and has high safety.
