The reaction properties of ethylene carbonate (EC) from aqueous solution of ethylene oxide (EO) and CO2 were studied by using a self-developed NY-2 catalyst. Orthogonal experiments were designed to determine the main factors affecting EO conversion rate and EC selectivity. The influence of the amount of solvent EC, reaction temperature, reaction pressure and catalyst on the synthesis reaction was discussed. The results show that N (H2O)∶ N (EO) is the most important factor affecting the conversion rate of EO. Temperature and N (H2O)∶ N chemical book(EO) are the most important factors affecting EC selectivity. The optimum reaction conditions were determined as follows: reaction temperature 100 ~ 120℃, reaction pressure 3.0 ~ 4.0MPa, mass fraction of catalyst 2%, N (H2O)∶ N (EO)=1∶2, N (EC)∶n(EO)=5. Under these conditions, the conversion rate of EO was 97.62% and the selectivity of EC was 92.55%.

At present, it is mainly used in three aspects. (1) used as sodium silicate slurry 1, 3-dioxacyclopentanone, potassium bicarbonate as curing agent and fast setting agent respectively to prepare non-hazardous sodium silicate slurry, due to acrylamide, urea system slurry was banned, water glass Chemicalbook slurry received widespread attention. (2) For the synthesis of furazolidone (C8H7N3O5, [67-45-8]; This is a broad-spectrum antibiotic used to prevent coccidiosis in chickens. (3) used as fiber finishing agent and other processing AIDS.
