Production Process Of Epoxy Soybean Oil

Epoxidized soybean oil is a chemical product made from soybean oil after oxidation treatment. It is a light yellow viscous oil liquid at room temperature. It is a widely used polyvinyl chloride nontoxic plasticizer and stabilizer. It has good compatibility with PVC resin, low volatility and small mobility. It has excellent thermal stability and light stability, water resistance and oil resistance. It can give products good mechanical strength, weatherability and electrical properties, and no toxicity. It is internationally recognized chemical process aids for food packaging materials.

In the presence of catalyst and stabilizer, the crude soybean oil is prepared by epoxidation with peroxisoxy carboxylic acid, which is refined for industrial products.

The peroxisocarboxylic acid here is usually obtained by the reaction of hydrogen peroxide with formic acid (or acetic acid).

In the presence of sulfuric acid, formic acid and hydrogen peroxide can produce peroxy formic acid, react with soybean oil, produce epoxide soybean oil, and restore formic acid to formic acid.

After mixing soya bean oil, formic acid, sulfuric acid and benzene, it slowly drops H2O2, and the reaction temperature begins to drop, and the reaction is the end point.

The reaction fluid was statically divided into lower layer of waste acid water. The oil layer was first neutralized by soda solution and then washed to neutral. After separating the water, the oil layer was distilled by steam distillation, the remaining products were vacuum distilled, the low boiling matter and water were removed, and the finished product was obtained by pressure filtration.
