Abstract: The epoxy fatty acid methyl ester is a kind of new environmental protection plasticizer using the fatty acid methyl ester as raw material. In the traditional production process, acid value, epoxy value, color, smell, and heating loss of the product by vacuum distillation technology are not ideal. The process uses flash distillation technology to achieve the product with high quality, light color and less smell. It has less 0.30% heating loss and 100^#(method of Pt-Co) color, and almost no smell.

Key words: epoxy fatty acid methyl ester, continuous dehydration and deodorizing, vacuum distillation, flash distillation
