The Application of Sonochemistry in the Organic Modification of Kaolinite Han Shirui, Liu Xuening, HU Nan, Gao Jianbiao, Yang Zhizhong Abstract Sonochemistry technique, which is different from traditional
chemistry intercalation techniques, has been adopted to improve the efficiency of
kaolinite intercalation. DMSO was used as an intercalation reagent in this experiment. The
experimental results indicated that the high intercalation effect could be obtained within
a shortened time and the displacement ratio could reach up to 90.9%. The influence of
sonochemistry reaction conditions on the intercalation efficiency is also discussed in
this paper.
超声化学法在高岭土有机改性中的应用 韩世瑞 刘雪宁 胡 南 杨治中*(中国科学院广州化学研究所 广州 510650) 摘要 采用超声化学法对高岭土进行层插，可以大大缩短处理时间，而且达到较理想的层插效果。实验在一定的超声条件下以二甲亚砜(DMSO)为层插剂对高岭土进行层插改性，只需3h，层插率达到90.9%。同时用SEM、DLS等方法对层插效果进行了表征, 并对不同超声条件对层插率的影响进行了探讨。关键词 超声化学 高岭土 二甲亚砜 层插 韩世瑞 女，25岁，硕士生，现从事纳米复合材料方面的研究工作。 *联系人，E-mail:zzyang@mail.gic.ac.cn2002-12-24收稿，2003-03-04修回 |
