Title:
マイクロ反応器によってオキセタン化合物を合成する方法
Document Type and Number:
Japanese Patent JP7438391
Kind Code:
B2
Abstract:
The present invention provides a method for synthesizing an oxetane compound by a microreactor. The synthesis method comprises: introducing trimethylolpropane and carbonate into the microreactor in the presence of an alkaline catalyst, and synthesizing the oxetane compound by means of a micro-reaction continuous flow process under an inert solvent or a solvent-free condition. Compared with conventional reactors, the microreactor has the advantages of being high in heat transfer mass transfer coefficient, good in mixing performance, easy to control in temperature, safe and controllable in process and the like. The three oxetane products are produced by utilizing the advantages of the microreactor, thereby greatly improving the mass transfer heat transfer performance of a reaction system, shortening the reaction time, improving the production efficiency, particularly avoiding the long-time high-temperature process in the pyrolysis process, reducing the production of high-boiling-point by-products, improving the yield, realizing continuity and automation of the process, and improving process safety. The reaction device required in the synthesis process is small in size and high in safety, and occupies a small area in a production site.
