Abstract Potassium fluoride incorporated on clinoptilolite nanoparticles (KF/CP NPs) by ion exchanging is found to be an effective and inexpensive heterogeneous nanocatalyst for chemoselective silylation of alcohols and phenols with 1,1,1,3,3,3-hexamethyldisilazane (HMDS) at room temperature. Nano-powder of clinoptilolite (CP) was prepared using a planetary ball mill mechanically method and characterized
摘要 发现通过离子交换掺入斜发沸石纳米颗粒(KF/CP NPs)上的氟化钾是一种有效且廉价的多相纳米催化剂,用于在 1,1,1,3,3,3-六甲基二硅氮烷 (HMDS)室内温度。采用行星式球磨机机械法制备斜发沸石(CP)纳米粉体,并通过动态光散射(DLS)、X射线粉末衍射(XRD)和扫描电子显微镜(SEM)分析表征。几乎所有产品都以高收率和短反应时间获得,并且催化剂也可以重复使用八次而没有损失其催化活性。
