| 摘 要： | 以环己酮为原料,酸性树脂为催化剂,在减压下进行缩合反应,得到中间体2-(1-环己烯基)环己酮。然后,在贵金属催化剂存在下,进行气相脱氢反应,合成邻苯基苯酚。考察了反应温度、2-(1-环己烯基)环己酮的进料流量、氢气的进料流量以及贵金属催化剂的预处理对邻苯基苯酚收率的影响。从而确定了合成工艺条件为:反应温度375℃;2-(1-环己烯基)环己酮的进料流量4mL/h;氢气的进料流量60mL/min;用去离子水洗涤处理贵金属催化剂。在此条件下,邻苯基苯酚的收率达94%以上。

| Abstract: | 2-Hydroxydiphenyl was prepared by catalytic dehydrogenation of 2-(1-cyclohexen-1-yl)cyclohexanone, obtained by catalytic condensation of cyclohexanone under reduced pressure. The effects of reaction temperature, feed rate and pretreatment methods of catalyst on dehydrogenation were studied. Under optimum conditions, the yield of 2-hydroxydiphenyl reached 94%. |
