摘　　要：制备了活性炭固载溴化1-(2-胺乙基氢溴酸)-3-甲基咪唑鎓盐离子液体催化剂,并用TG和XPS对催化剂进行了表征。将该催化剂首次用于Knoevenagel缩合反应,结果表明活性炭固载离子液体催化剂具有良好的催化活性和稳定性,同时克服了均相催化剂难以分离的不足。Ionic liquid/activated carbons （AC） catalysts have been prepared by a chemical method that involves functionalization of AC with 1-（2-amine ethyl hydrogen）-3-methylimidazoliurn bromide ionic liquids. It was used in Knoevenagel condensation reaction for the first time.The immobilized IL was then characterized by X-ray photoelectron spectroscopy and thermogravimetric analysis （TGA） spectra. Ionic liquid/activated carbon （AC） catalyst showed good catalytic performance toward Knoevenagel condensation reaction,and overcome the inseparable shortage of the homogeneous catalyst.
