Coupling of Ethylene Glycol and Dimethyl Carbonate
This method can be divided into two main steps: first, carbon dioxide and ethylene oxide react under a catalyst to synthesize ethylene carbonate, which then reacts with additional methanol to form ethylene glycol and dimethyl carbonate. The advantages of this method include:
Utilization of CO₂, a by-product of ethylene oxide production, to reduce raw material costs and greenhouse gas emissions.
Ethylene carbonate has excellent performance, serving as a versatile chemical product with safe storage and transportation. It can be used as an intermediate for ethylene glycol production or directly sold as a finished product, avoiding the high energy consumption and impurity issues associated with water as a raw material.
The by-product, dimethyl carbonate, has high added value and is a widely used basic chemical raw material.
The atomic utilization rate reaches 100%, classifying it as a "zero-emission" clean production process.
