Method for synthesizing epoxy fatty acid methyl ester by using microchannel reactor

The present invention discloses a method for synthesizing epoxy fatty acid methyl ester by using a microchannel reactor. The method comprises: mixing formic acid, hydrogen peroxide, a catalyst of concentrated sulfuric acid, and a stabilizer EDTA-2Na to obtain a mixture; adding he mixture and fatty acid methyl ester into the microchannel reactor via two inlets separately, keeping the reaction time for 10 min to 22 min, carrying out poxidation at temperature of 60 DEG C to 80 DEG C, and delaminating and washing the obtained product to obtain epoxy fatty acid methyl ester. According to the method provided by the present invention, the problems of long reaction time, incapability of continuous production and low safety performance, etc. that exist in a current process of producing epoxy fatty acid methyl ester by using a batch reactor are overcome. The continuous production and automatic control of the process can be implemented, so that the production is efficient and safe, and energy consumption is reduced.
