ESO is soluble in hydrocarbon compounds, ketones, esters, higher grade alcohols and other organic solvents, slightly soluble in ethanol as well.

ESO is the most widely used PVC nontoxic plasticizer and stabilizer. It is particularly consistent with PVC and has low volatility and mobility. Its high thermal stability, light stability and good resistance to water and oil endow the products with better mechanical strength, weather resisting property and electrical property. Its non-toxicity makes it the internationally acknowledged chemical aid for foodstuff wrapper.ESO can be applied to all PVC products, such as, foodstuff wrapper, medical ware, pellicle, sheet material, tubular goods, sealing plate of icebox, artificial leather, floor leather, wire and cable material, plastic wallpaper and other daily use plastic products. It can also be applied to making special printing ink, oil paint, coating material, synthetic rubber, and liquid compound stabilizer and so on.

How Does The Production Of ESO Work?

ESO uses benzene as a solvent and sulfuric acid as a catalyst. Soybean oil, formic acid and benzene are prepared into a mixed liquid, and hydrogen peroxide is added dropwise under stirring to carry out the epoxidation reaction. After completion, let it stand to separate the waste acid water, and wash the oil layer with dilute lye and soft water to neutrality. After oil-water separation, the oil layer must be distilled, the distilled benzene-water mixture is separated by condensation, the benzene is returned for reuse, the kettle liquid is subjected to vacuum distillation, and the finished product fraction is intercepted. It can trigger at a certain temperature. The added stabilizer stabilizes the generated peroxyformic acid, ensuring that the oxygen atoms released by the peroxyformic acid can fully contact the unsaturated bonds in the ESO, thereby making the epoxy The chemical reaction proceeds towards the product direction.

The above situation is the process of preparing epoxy soybean oil. I hope it will help you to some extent. Thank you for seeing this.
