摘要: 在制备水滑石的过程中使用了微波技术进行晶化,并与常规晶化方法进行了对比.XRD结果表明微波晶化法可以在约8分钟内达到常规热晶化法24小时一样的效果.在制备1,5-萘二磺酸柱撑水滑石的过程中,使用了微波技术进行离子交换插入.XRD结果表明,微波作用10分钟与常规热交换法72小时具有一样甚至更好的离子交换效果.用微波插入法制备了磷钨酸柱撑水滑石,XRD和TPDE结果表明磷钨酸分子与水滑石层板离子之间形成了强烈的相互作用.

Abstract: Hydrotalcite Mg6 Al2(OH) 16 CO3·4H2O has been prepared by using both microwave irradiation and conventional heating methods during the ageing process. X-ray diffraction show s that the same materials are obtained in each case, but the microwave process is superior in that a much shorter aging time is required. Mg4 Al2(OH) 12[C10 H6(SO3) 2]·4H2O has been prepared by using microwave and conventional heating methods during the intercalation process. XRD indicates that the sample produced by the microwave method is superior to that produced by conventional heating. Mg4Al2(OH) 12(PW12O40) 2/3·4H2O has been prepared by microwave methods. XRD and TPDE show that there is a strong interaction between the heteropolyanion and the layers of hydrotalcite.

Key words: microwave techniques, hydrotalcite, hydrotalcite-like compounds
