Abstract

The invention discloses a production method of epoxidized soybean oil. The invention adopts a two-step synthesis method, and the method includes the steps of: (1) adding hydrogen peroxide, formic acidand a catalyst into a high-pressure reaction kettle, conducting stirring and cooling to obtain peroxyformic acid; (2) adding soybean oil dropwise into the peroxyformic acid obtained by step (1), introducing oxygen, performing stirring and carrying out pressurizing reaction to obtain a crude epoxidized soybean oil product; and (3) conducting alkali washing, water scrubbing and reduced pressure distillation on the crude epoxidized soybean oil product obtained by step (2) to obtain an epoxidized soybean oil finished product. Compared with the prior art, the method provided by the invention has the advantages of low cost, good reaction temperature controllability, fast reaction speed and few by-product, and the obtained product has good quality.

Description

technical field

[0001] The invention belongs to the technical field of inorganic chemical synthesis, and in particular relates to a production method of epoxidized soybean oil. Background technique

[0002] Epoxidized soybean oil is a non-toxic non-benzene environment-friendly plastic additive-plasticizer widely used at present. It has dual properties of plasticization and heat stability, and is non-toxic, safe and environmentally friendly, so it is favored by the plastic products industry. Favored, widely used in plastics, coatings, new polymer materials, rubber and other industrial fields. With the improvement of environmental protection awareness in all countries in the world, the toxicity of plasticizers has attracted more and more attention; plasticizer phthalate products are suspected of causing cancer, and many developed countries have banned them from being used in medical treatment, food packaging, and daily necessities. , toys and other plastic products. Moreover...
