- Safe, environment-friendly and controllable synthetic process of di-epoxide
-
The invention relates to the field of synthesis of epoxide, and more specifically, relates to a safe, environment-friendly and controllable synthetic process of di-epoxide. The synthetic process of the di-epoxide at least comprises the following steps: mixing diolefin, carboxylic acids, basic salt and solvent, and cooling; dropwise adding a hydrogen peroxide solution for 1-12 h; standing for layering to obtain a lower layer organic phase-1, washing the organic phase-1 with a cleaning solution, and standing for layering to obtain a lower layer organic phase-2; purifying. The reaction system ofthe synthetic process is simple, environmentally friendly, safe and controllable, is low in production cost, and can meet the requirements of technical economy; the prepared di-epoxide is high in purity and yield and low in solvent content, chroma and halogen content, and is suitable for large-scale industrial production.
