  • What is epoxidized soybean oil (eso)?
  • (ESO) is a group of organic compounds obtained from the epoxidation of soybean oil. It is used as a plasticizer and stabilizer in polyvinyl chloride plastics. Epoxidized soybean oil is a pale yellow viscous liquid. It is used as a plasticizer and stabilizer in plastic materials, especially PVC and its copolymers, to keep these plastics soft and flexible.
  • Is epoxidized soybean oil a plasticizer for PVC?
  • Epoxidized soybean oil is one of the additives in the PVC gasket. It serves as a plasticizer and a scavenger for hydrochloric acid released when the PVC degrades thermally, e.g. when the gasket is applied to the lid and food product undergoes sterilization. ESBO is also used in PVC cling films for wrapping foods and toys.
  • What is ring opening of epoxidized soybean oil?
  • Biopolyol synthesis via ring-opening of epoxidized soybean。It is noteworthy that during the ring-opening process of epoxidized soybean oils (ESO), catalysts play a crucial role in achieving desirable biopolyol products with a high epoxy ring-opening rate and a great hydroxyl number.
  • How is epoxidized soybean oil made?
  • There are two main production methods for epoxidized soybean oil: solvent method and solvent-free method. The specific production methods include peroxyformic acid oxidation method, ion exchange resin catalysis method, aluminum sulfate catalysis method, peroxycarboxylic acid oxidation method and phase transfer catalytic oxidation method.
