摘要: 利用丁基三苯基澳化磷(BTPB)、十二烷基三苯基嗅化麟(DTPB)湿法改性天然钠基蒙脱土。X射线衍射、红外光谱测试表明嶙阳离子已插层到蒙脱土片层间并成功打开层间距;热重分析结果表明DTPB和BTPB改性的蒙脱土比十六烷基三甲基嗅化按改性蒙脱土的热分解温度分别提高102℃和57℃;沉降实验研究表明改性后蒙脱土在甲苯、苯乙烯中表现出很好的分散性和溶胀性。

Abstract: In this article, Na-montmorillonite (Na-MMT) was modified by butyltriphenyl phosphoninm bromide ( BTPB ) and dodecyl triphenyl phosphonium bromide(DTPB).Sedimentation experiments showed that modified montmorillonite had better dispersibility and swelling property in organic solvent containing toluene and benzene. XRD and FTIR demonstrated that the quaternary phosphonium cationic had intercalated interlayer of montmorillonite and the interval distance of montmorillonite was obviously enlarged. TG curves show that the initial decomposition temperature of quaternary phosphonium modified montmorillonite rose by 102 C and 57℃,respectively, in comparison of that based on quaternary ammnnimm salt.

Key words: quaternary phosphonium salt, montmorillonite, intercalation modification
