摘　　要：本文以SO42-/ZrO 2-NiO/Al2O 3固体超强酸为催化剂,以1,5-戊二醇和氨水为原料,经固定床反应器合成了哌啶。研究原料的摩尔配比,反应温度,以及原材料进料速度对合成反应的影响;实验结果表明合成哌啶的最优实验方案为:氨水与1,5-戊二醇原料物质的量之比为13∶1,反应温度为380℃,进料速度为1.0 mL·min^(-1),哌啶的收率最高达到95.2%。In this paper,piperidine was synthesized in a fixed bed reactor catalyzed by SO 42-/ZrO 2-NiO/Al 2O 3 solid superacid using 1,5-pentanediol and ammonia as raw materials.The influence factors,such as molar ratio of raw materials,reaction temperature,and feed rates of raw materials were investigated.The optimal experimental plans for the synthesis of piperidine were obtained:the mole ratio of ammonia and 1,5-pentanediol was 13∶1,reaction temperature was 360℃,the feed rate was 1.0 mL·min^(-1),and the yield of piperidine could be up to 95.2%.
