为寻找一种用于制备1,2-丙二醇（PG）的更有效简单的离子液体,通过在咪唑阳离子上引进碱性基团,合成了具有一个碱性位点的咪唑类离子液体,并将其固载到介孔分子筛SBA-15上,制得功能化三乙胺固载离子液体材料。采用红外、热重、X射线衍射、透射电镜、N2吸附-脱附等测试技术对催化剂进行了表征。通过表征分析可知,与纯硅SBA-15相比,固载催化剂的比表面积、孔容和孔径有一定程度的减小。考察了其在碳酸丙烯酯水解反应中的催化活性,在有足够水的条件下,反应温度140℃、催化剂的用量为3%（质量分数）、反应时间为2 h时,取得最好的催化效果,选择性和产率均大于99%,同时该催化剂具有重复使用性。

A room temperature ionic liquid,1-allyl-3-methylimidazolium tetrafluoroborate(BF4) was prepared by a two-step synthesis.Then gel polymer electrolytes(GPE) prepared by incorporating the ionic liquid BF4 and poly(methyl methacrylate)(PMMA) were modified with aprotic solvents propylene carbonate(PC) and dimethyl carbonate(DMC) and SiO2 nano particles.The structure and properties of the GPE were studied by means of fourier transform infrared spectroscopy(FT-IR),A.C.impedance(AC),thermogravimetry(TG),and scanning electron microscope(SEM).The results showed that the introduction of aprotic solvents PC-DMC and nano-SiO2 particles increased the ionic conductivity of the GPE,which showed a highly ionic conductivity of up to 5.25×10-3 S/cm at room temperature.In addition,the conductive behavior of the GPE follows an Arrhenius equation.The gel polymer electrolytes shows high thermal stability and tends to decompose at temperature higher than 300 ℃.

The IL-Pro/SBA-15 catalyst was prepared using SBA-15 as the support to immobilize ionic liquid proline, which was synthesized from L-proline. The IL-Pro/SBA-15 catalyst was characterized by FT-IR spectroscopy, thermal gravity analysis-derivative thermogravimetry, N-2 adsorption-desorption, X-ray diffraction, and transmission electron microscopy, and the catalytic performance of the catalyst was measured for Knoevenagel reaction. The results showed that the mesoporous structure of SBA-15 was not affected by immobilization; however, the pore diameter, pore volume, and surface area were decreased. Mass loss of the supported ionic liquid occurred at 250-360 degrees C, and reached the maximum at 310 degrees C. The Pro-IL/SBA-15 catalyst had higher activity in Knoevenagel reaction of benzaldehyde with malononitrile and gave the corresponding product yield of 94%. The supported catalyst could be easily separated from the reaction system and reused at least seven times without loss of catalytic activity.
