摘　　要：采用高温水热合成法,在强碱性条件下制备了有序性高、具有三八面体结构的皂石材料,并对其进行了铝柱柱撑.通过XRD、27Al MAS NMR、N2吸附-脱附、吡啶红外、TGA-DTA和TEM等手段对材料进行了物化表征,并用临氢异构反应研究了材料的催化性能.结果表明,层柱皂石具有很高的结构有序性,800℃以上时热稳定性良好,且具有较好的正癸烷临氢异构转化率及异构产物收率.Well-ordered trioctahedral saponites were successfully synthesized in strong basic system under high temperature and were intercalated with Keggion ions.XRD,27Al MAS NMR,N2 adsorption and desorption,FTIR spectra of pyridine adsorption,TGA-DTA and TEM were used for the characterization of the synthetic aluminum-pillared saponites.The results illustrate that pillared saponites are highly-ordered and thermal stable above 800 ℃.Besides,after being pillared by aluminium oligmer,the Al-pillared synthetic saponites show high conversion and hydroisomerization yield in the catalytic reaction of n-decane.
