介孔材料具有很大的比表面和很规则的孔大小及孔形状,以化学键键合有机基团的介孔材料又兼有官能团的特性,实现了不少有机均相催化剂的固载.与广泛应用的酸性分子筛相比,人们很少关注碱性介孔材料.经过研究者们的不断工作,固体碱可以应用于Knoevenagel反应、Michael加成、单甘油脂合成反应等方面,原位红外技术具有方便、实时、准确、有效等优点.可以检测样品对气体的吸附,或者在真空、惰性等条件下对样品焙烧的情况.
Aminopropyl-incorporated mesoporous molecular sieve MCM-41 was post-modlfied by piperidine. The prepared P-AM-MCM-41 was invesitigated referring to the adsorption of CO2 under temperature-programmed heating conditions, providing with some instruction for its application in the solid-base catalysis.
