摘　　要：为提高钯碳催化剂在反应中的稳定性,本实验采用等体积浸渍的方法,将离子液体(ionic liquid,IL)引入钯碳催化剂中,还原制备催化剂Pd-IL/C。对催化剂进行表征并考察其在氯代苯酚的脱氯加氢反应中的催化活性与稳定性。结果表明,加入离子液体制备得到的催化剂Pd-IL/C在脱氢加氯反应中的催化活性高于未加入离子液体制备得到的钯碳催化剂Pd/C,并且制备得到的催化剂Pd-IL/C具有良好的稳定性。In order to improve the stability of the palladium carbon catalyst in the reaction,an ionic liquid(IL)was introduced into the palladium carbon catalyst by an equal volume impregnation method,and the catalyst Pd-IL/C was prepared by reduction.The catalyst was characterized and its catalytic activity and stability in the dechlorination and hydrogenation of chlorophenol were investigated.The results show that the catalytic activity of Pd-IL/C prepared by adding ionic liquid in dehydrochlorination reaction is higher than that of Pd/C catalyst prepared by adding ionic liquid,and the prepared catalyst Pd-IL/C has good stability.
