| 摘 要： | 用离子交换法制备了十二烷基苯磺酸柱撑水滑石(LDH-DB)、十二烷基硫酸柱撑水滑石(LDH-DS)和硬脂酸柱撑水滑石(LDH-St),并通过XRD、FTIR和TGA对改性前后LDH的结构进行了表征.结果表明:当有机阴离子与LDH物质的量比为2、反应温度为70～80,℃、反应时间为2,h、反应pH为4时,有机阴离子可以插入水滑石层间完全取代CO23-,且反应生成的柱撑水滑石具有完整的层状结构.

| Abstract: | Layered double hydroxides(LDH) pillaring with DB-,DS- and St- were directly synthesized by ion exchange method and the LDH products were characterized through XRD,FTIR,and TGA.The results show that initial interlayer car-bonates of the hydrotalcite can be completely replaced by organic anions when the organic anions/LDH=2,reaction temperature between 70,℃and 80,℃,pH=4 and reaction time over 2 hours.The pillared hydrotalcite have a complete lamellar structure. |
