Ethylene Glycol Production via Intermediate Compounds
Hydrolysis of Ethylene Carbonate
The hydrolysis of ethylene carbonate to produce ethylene glycol involves the reaction of carbon dioxide and ethylene oxide under a catalyst to form ethylene carbonate, which is then hydrolyzed to ethylene glycol. Compared with traditional ethylene glycol production, this method offers multiple advantages:
Higher selectivity for ethylene glycol, reaching 99.3%–99.4%.
Significantly lower production costs for the same output.
Milder reaction conditions (low temperature and pressure), reducing the requirements for equipment strength and lowering investment costs by approximately 10%.
Operating costs reduced by about 5%, leading to better economic viability, energy conservation, and environmental protection.
