Triphase Catalytic Reactions
Using Clay Intercalates
N Shabestary S Khazaeli and N Long
A naturally occurring clay mineral hectorite was used as the support for quaternary ammonium
cations The intercalation of the cations by the clay has the advantage of separation of the
catalyst from the product by a simple ltration technique Several quaternary ammonium cation
clay intercalates have been used to investigate the eects of alkyl chain length size and shape of
these catalysts in converting nbutyl bromide to nbutyl chloride It appears that the hectorite
intercalates have a great tendency for emulsication in the presence of organic solvent toluene
and water In fact the emulsication being facilitated by the clay intercalates helps to bring the
nucleophile from the aqueous phase into contact with the substrate which is contained in the
organic phase The rate of the reaction was measured for the biphase reaction

题目：使用粘土交替插入物的三相催化反应
下面一行是作者，不用翻译
内容：使用一种天然的粘土矿物hectorite作为四价铵阳离子的载体。
阳离子中交叉插入粘土的优点在于用简单萃取的方法即可从产物中将催化剂分离出来。
在将正溴丁烷转化为正氯丁烷的反应中，试验了几种不同的四价铵阳离子粘土插入催化剂来研究催化剂中烷基链的长度、大小和形状的作用。
结果表明，hectorite交叉插入物在有机溶剂甲苯和水中有很强的emulsication 趋势（你这里乱码了，自己查这个词去吧）。
实际上，emulsication 粘土交叉插入物帮助亲电试剂从水相中带到有机相中的底物那里与之作用，从而增强了emulsication 。
对不使用粘土作为载体的两相反应和使用粘土载体的三相反应，分别测量了反应速率作为比较。根据选用催化剂的不同，反应速率有很大差异。
研究结果表明，具有某些特定碳原子数的四价铵阳离子具有更高的催化活性。
