Ethylene Carbonate Ionic Liquid Catalyst Successfully Developed by Liaoyang Petrochemical Company

摘要

The Liaoyang Petrochemical Company has successfullydeveloped a novel ionic liquid catalyst for carbonylationof ethylene oxide with carbon dioxide to form ethylenecarbonate （EC）. This catalyst can achieve an 100 % conversionand a 98% selectivity at low temperature andunder low pressure, featuring high catalytic activity, goodstability, good adaptability to feedstocks and low productioncost.
