Claim:
1. A method for preparing a high-quality epoxidized fatty acid ester with a micro-reaction device, comprising the following steps: (1) respectively pumping an aqueous hydrogen peroxide solution and a carboxylic acid at the same time into a first micro-mixer of the micro-reaction device, completely mixing them and then introducing the mixture into a first micro-reactor of the micro-reaction device to react; and (2) respectively pumping the output material of the first micro-reactor and an unsaturated fatty acid ester at the same time into a second micro-mixer of the micro-reaction device, completely mixing them and then introducing the mixture into a second micro-reactor of the micro-reaction device to react completely, water-rinsing the organic phase part of the resultant reaction liquid and drying to obtain the epoxidized fatty acid ester.
