摘　　要：以天然钙基膨润土为原料,经碳酸钠钠化后,用溴代十六烷基三甲胺进行有机包覆,制得有机膨润土;通过TG分析和正交实验,探讨了有机膨润土结构及最佳制备工艺。Organic bentonite was prepared from natural Ca base bentonite. The latter was first treated with sodium carbonate, and then was covered with cetyl trimethyl ammonium bromide. The optimal process conditions were found by orthogonal technique, and the products were characterized by TG.
