Diacetoxy Epoxidized Soybean Oil Glycerol Ester is an important compound mainly derived from vegetable oils, especially soybean oil. The following is a detailed introduction to its properties, uses, manufacturing methods, and safety:
nature
Chemical structure: This compound has the characteristics of epoxy and acyloxy groups, which gives it good reactivity and stability.
Appearance: Usually a light yellow transparent liquid or viscous liquid.
Solubility: soluble in organic solvents such as alcohols, ketones, and ethers, but with lower solubility in water.
Thermal stability: It has good thermal stability and can be applied at higher temperatures.
Plasticity: It has excellent plasticizing properties and can improve the flexibility of plastic or rubber materials.
purpose
Plasticizers: widely used in plastics such as polyvinyl chloride (PVC) and polyolefins to improve their flexibility and ductility.
Coatings and inks: As stabilizers for coatings and inks, they help improve the fluidity and adhesion of materials.
Synthetic resin: As one of the raw materials for synthetic resin, it improves the characteristics of the resin.
Food contact materials: Due to their origin from natural vegetable oils, they are also used in materials that come into contact with food in some applications.
Manufacturing method
Raw material selection: Soybean oil is the main raw material.
Epoxidation reaction: By reacting soybean oil with an epoxidizer (such as epichlorohydrin), epoxidized vegetable oil is generated.
Acylation reaction: The epoxidized product undergoes acylation reaction with acetic acid under the action of a catalyst, ultimately obtaining diacetyl epoxyphytooleate glycerol ester.
Separation and purification: After reaction, unreacted substances are removed by distillation, filtration, or other separation methods to obtain pure products.
Security
Toxicity: Diacetyl epoxy plant oleic acid glyceride is generally considered to be low toxicity, but it still needs to be handled in accordance with relevant safety standards.
Safety protection: During operation, it is recommended to wear appropriate personal protective equipment (such as gloves, goggles, and masks) to reduce contact with the skin and respiratory tract.
Environmental impact: Due to its plant-based origin, it is generally considered environmentally friendly, but good waste disposal procedures must still be followed to avoid polluting water bodies and soil.
