摘　　要：探讨了1,4-丁二醇选择性催化脱水制备3-丁烯-1-醇的工艺技术。探讨了焙烧温度、金属氧化物掺杂,以及气液比、反应温度对反应工艺的影响,并分析了催化剂的性能表征。结果显示:在CaO-ZrO_(2)类催化剂中掺杂SnO_(2)和Bi_(2)O_(3),可提升1,4-丁二醇转化率及3-丁烯-1-醇收率;反应温度与焙烧温度相同时,CaO-ZrO_(2)-SnO_(2)催化剂的催化性能更好;在380℃的反应温度下,CaO-ZrO_(2)-SnO_(2)作催化剂,1,4-丁二醇转化率及3-丁烯-1-醇收率达到最佳。研究结果对利用1,4-丁二醇选择性脱水制备3-丁烯-1-醇的工艺开发具有参考价值。The process development for the selective catalytic dehydration of 1,4-butanediol to 3-buten-1-ol was investigated.The conver-sion of 1,4-butanediol and the yield of 3-buten-1-ol were analyzed.The specific effects of roasting temperature,metal oxide doping on the catalyst,and gas-to-liquid ratio and reaction temperature on the reaction process were investigated,and the performance characterization of the catalyst was analyzed to obtain the best performing catalyst.The experimental results showed that the doping of SnO_(2) and Bi_(2)O_(3) in CaO-ZrO_(2)-like catalysts could enhance the conversion of 1,4-butanediol and the yield of 3-buten-1-ol;the catalytic performance of CaO-ZrO_(2)-SnO_(2) catalysts was better when the reaction temperature was the same as the roasting temperature;at the reaction temperature of 380℃,the CaO-ZrO_(2)-SnO_(2) catalysts showed better catalytic performance for the 1,4 At 380℃,the CaO-ZrO_(2)-SnO_(2) catalyst achieved the best conversion of butanediol and yield of 3-buten-1-ol.The results of this study are of reference value for the process development of 3-buten-1-ol preparation using selective dehydration of 1,4-butanediol.
