甘油，威胁生物柴油工业的生存能力，可以转化为有价值的化学品和化学中间体，如甘油碳酸酯（GC）。以天然白云石为原料制备CaO-MgO复合氧化物催化剂，催化碳酸二甲酯（DMC）与甘油酯交换合成GC。在800 ℃的煅烧温度下，天然白云石转化为CaO-MgO混合氧化物，用作甘油转化为GC的催化剂。温度变化和煅烧白云石的表面和结构特征导致甘油与DMC的酯交换反应生成GC。催化剂的分子量为15
Glycerol, which threatens the viability of biodiesel industries, can be converted to valuable chemicals and chemical intermediates, such as glycerol carbonate (GC). GC was synthesized by glycerol transesterification with dimethyl carbonate (DMC) Cao-MgO mixed oxide catalyst prepared from natural dolomite. At calcination temperature of 800 degrees C, natural dolomite was converted to CaO-MgO mixed oxide to serve as catalyst in the conversion of glycerol to GC. Temperature changes and calcined dolomite surface and textural characteristics caused the glycerol transesterification with DMC to GC. The catalyst with 15< H_
