摘要:已经实现了使用dmc的新型异质酸(纳米晶体zsm-5)催化醇的羧甲基化为不对称的碳酸烷基酯.通过水热结晶合成了晶体大小为20-30 Nm的纳米晶体zsm-5(nzsm-5).合成的nzsm-5通过x射线衍射,傅立叶变换红外光谱和固态NMR进行验证.透射电子显微镜和扫描电子显微镜证实了nzsm-5的形态,揭示了由纳米大小(20-30 Nm)的nzsm-5颗粒堆积形成的沸石(100-200 Nm)聚集体的形成.nzsm-5的理化性质通过氮的吸附和程序升温的氨解吸来测量,这表明表面积为465 M 2 G-1酸度为0.936 Mmol G-1.本协议为高产量的各种非对称碳酸烷基酯提供了一种有吸引力的方法.催化剂被有效地循环多达5个连续循环.这种方法拓宽了dmc在绿色化学中可能的利用范围.
