New technique of dimethyl carbonate / ethylene glycol catalyzed by ionic liquid

New technique for the production of dimethyl carbonate (DMC) and ethylene glycol (EG) catalyzed by ionic liquids was developed. Some key technical issues for application and industrialization were investigated in detail. The problem of large-scale preparation of catalysts has been solved. The parameter for the design and selection of key equipments has been obtained. System integration for progress has been optimized. One PCT patent has been authorized and 5 Chinese invention patents have been authorized. The 20,000 t/a industrial demonstration plant is now in progress. The results have passed detailed appraisal of Chinese Academy of Sciences and total technique has reached top level of international same kind technique.
