Heterogenous catalysis solid alkali catalyst, and its preparing method and use

A solid alkali catalyst with high stability and activity for the multi-phase catalytic synthesis of dimethyl carbonate is composed of calcium oxide (10-30 mass %) and zirconium oxide (70-90). Its preparing process is also disclosed, which features that the CaCl2 or Ca (NO3)2 and ZrOCl2 or ZrO (NO3)2...

Summary:A solid alkali catalyst with high stability and activity for the multi-phase catalytic synthesis of dimethyl carbonate is composed of calcium oxide (10-30 mass %) and zirconium oxide (70-90). Its preparing process is also disclosed, which features that the CaCl2 or Ca (NO3)2 and ZrOCl2 or ZrO (NO3)2 are used as its Ca source and Zr source.
