An effective combination catalyst of CeO and zeolite for the direct synthesis of diethyl carbonate from CO and ethanol with 2,2-diethoxypropane as a dehydrating agent

The combination catalyst of CeO 2 and H-FAU zeolite was effective for the direct synthesis of diethyl carbonate from CO 2 and ethanol with 2,2-diethoxypropane as a dehydrating regent, where H-FAU catalyzed hydrolysis of 2,2-diethoxypropane. The combination catalyst provided high activity and a high...

Description
Summary:The combination catalyst of CeO 2 and H-FAU zeolite was effective for the direct synthesis of diethyl carbonate from CO 2 and ethanol with 2,2-diethoxypropane as a dehydrating regent, where H-FAU catalyzed hydrolysis of 2,2-diethoxypropane. The combination catalyst provided high activity and a high diethyl carbonate yield of 72% based on 2,2-diethoxypropane at a low temperature of 393 K. The combination of CeO 2 and H-FAU zeolite acted as an effective heterogeneous catalyst for the direct synthesis of diethyl carbonate from CO 2 and ethanol with 2,2-diethoxypropane as a dehydrating agent.
