| 中文摘要: |
| 在连续流动性固定器中,以丙烯醛二甲缩醛、水和氨为原料合成吡啶和3-甲基吡啶.多种重要的影响因素被详细地考察,包括碳源、催化剂、反应温度、液相空速和丙烯醛二甲缩醛/氨/水摩尔比.研究结果表明,与丙烯醛/氨路线相比,丙烯醛二甲缩醛/氨路线能平稳运行,其反应条件对吡啶和3-甲基吡啶总收率产生巨大的影响.最优化的反应条件为: HZSM-5为催化剂、反应温度为450 oC、液相空速为0.75 h-1和丙烯醛二甲醛/氨/水物质的量之比为1/3.5/1.在产物中未检测到4-甲基吡啶. |
| 英文摘要: |
| In this work,the synthesis of acrolein dimethyl acetal and ammonia toward pyridine and 3-picoline is conducted in a fixed-bed reactor.Various influencing parameters,including carbon resources,types of catalysts,reaction temperature,liquid hourly space velocity and reactant ratios,are investigated in details.The results show that the reaction using (acrolein dimethyl acetal)/ammonia is well operated,as compared to acrolein/ammonia.The reaction conditions have great affect on the total yield of pyridine and 3-picoline.The optimal conditions are as follows:HZSM-5 acting as catalyst,reaction temperature=450 oC,liquid hourly space velocity=0.75 h-1 and mole ratio of (acrolein dimethyl acetal)/ammonia/water=1/3.5/1.In addition,4-picoline is not detected in the final products. |
