Epoxy Oil is also known as Epoxidized Soybean Oil. It may be a mixture of Triglycerides. It is a viscous liquid with a yellowish tinge. Epoxy Oil is produced through an epoxidation process. Polyunsaturated Vegetable Oils are used as precursors for the epoxidation process because they have high carbon-carbon double bonds. A peroxide or peracid is then used to add an atom of Oxygen. This additional Oxygen atom converts the Carbon-Carbon bond into an Epoxide group. Epoxidation of Soybean Oil is followed by Transesterification of the Soybean Oil followed by the Epoxidation of Esters.
