报道了温和条件下甘油和碳酸二甲酯在一系列不同Mg/Al比(0.5-6)的Mg-Al水滑石催化下合成碳酸甘油酯(GC)的反应.发现， Mg-Al水滑石对该反应具有很高的GC选择性，其中Mg/Al =2经400oC处理所得水滑石催化效率最高：70 oC反应3 h甘油转化率达66.9%时， GC选择性维持在97%以上.表征结果表明，水滑石样品的比表面积、孔径、结晶度和表面碱性对其催化活性影响很大.

Glycerol carbonate (GC) was synthesized via the catalytic transesterification of glycerol with dime-thyl carbonate over a series of Mg-Al hydrotalcites with different Mg/Al ratios (0.5-6) under mild conditions. All catalysts exhibited a high selectivity toward GC. The sample with Mg/Al = 2 exhibited 97.1% of selectivity toward GC and 66.9% of glycerol conversion at 70 °C for 3 h. Characterization results indicated that the activity of calcined Mg-Al hydrotalcites depended mainly on the surface area, pore diameter, and crystallinity.
