Ethylene carbonate, propylene carbonate is a good solvent and propylene carbonate solvent. It is widely used for the removal of CO2 and H2S from natural gas, oilfield gas and synthetic ammonia raw materials. In textile printing and dyeing, it is a good solvent for polyamide, polyethylene nitrile, bisphenol resin and so on, vinyl carbonate ester

In the synthetic fiber industry, it can be used as a bulking agent to improve the properties of fiber, improve the feel of fabric and improve the wrinkle resistance. In printing and dyeing, it can strengthen the printing and dyeing properties of hydrophobic synthetic fiber, make the dyeing distribution uniform, improve the performance of sun fading. Used as a paint removal solvent in the paint industry. In plastic processing as a solvent or directly used as a plasticizer. Used as electrolyte in the capacitive battery industry. In medicine as a cortisone ointment base ingredients.

This technology integrates chemical engineering, fine chemical engineering, environmental engineering, systems engineering and other disciplines, penetrates, merges and systems integration, and uses carbon dioxide waste gas to directly synthesize ethylene (propylene) carbonate ester with ethylene (propylene) oxide in the near critical state of carbon dioxide. Compared with the original process, each ton of product can save 42 tons of cooling water, 826kg of steam, 120Kwh of electricity and about 50kg of propylene oxide. At the same time, equipment investment was reduced by more than 20%.
