Brӧnsted-Lewis acidic ionic liquids (BLAILs)[3-methyl-1-(3-sulfonic acid) imidazolium zinc sulfate ([MIMPS]+(1/2Zn²⁺)SO₄^2-)] with Brӧnsted acid ionic liquid [MIMPS]+HSO₄- and ZnO were synthesized, and their acidities were determined by infrared pyridine probe. Ti doped SBA-15 mesoporous molecular sieves (Ti-SBA-15) were synthesized by co-condensation method. Ionic liquid [MIMPS]+(1/2Zn²⁺)SO₄^2- and Ti-SBA-15 are compounded at different mass ratios by impregnation method. FT-IR, TG, XRD, N₂ physical adsorption, elemental analysis, mass spectroscopy, TEM, and XPS were used to characterize the composition and structure of the catalysts. The catalytic activities of catalysts were investigated via esterification of acetic acid with benzyl alcohol (BnOH). When the reaction temperature is 90 ℃, reaction time is 3 h, nbenzyl alcohol/nacetic acid =1.8, and the amount of catalyst was 0.4 g, the conversion of acetic acid was as high as 93.8%. After 5 cycles, the conversion of acetic acid decreased only 5%, suggesting that the resulting catalyst had good stability.

布朗斯台德-刘易斯酸性离子液体（BLAILs）[3-甲基-1-（3-磺酸）咪唑鎓硫酸锌（[MIMPS] +（1 / 2Zn ²⁺）SO ₄ ^2-）]与布朗斯台德酸性离子液体[MIMPS合成了] + HSO _4-和ZnO，并用红外吡啶探针测定了其酸度。采用共缩聚法合成了掺钛的SBA-15介孔分子筛（Ti-SBA-15）。通过浸渍法将离子液体[MIMPS] +（1 / 2Zn ²⁺）SO ₄ ^2-和Ti-SBA-15以不同的质量比混合。FT-IR，TG，XRD，N ₂物理吸附，元素分析，质谱，TEM和XPS用来表征催化剂的组成和结构。通过乙酸与苯甲醇（BnOH）的酯化反应研究了催化剂的催化活性。当反应温度为90℃，反应时间为3h，正苯甲醇/乙酸= 1.8，催化剂用量为0.4g时，乙酸的转化率高达93.8％。5个循环后，乙酸的转化率仅降低了5％，表明所得催化剂具有良好的稳定性。
