【摘要】 在系列NiMo/Al2 O3 催化剂上考察了环戊酮转化为环戊硫醇的反应。根据反应结果推断 ,该硫醇化反应分两步进行 ,第一步为环戊酮和H2 S生成环戊硫酮 ,第二步为环戊硫酮加氢生成环戊硫醇。在部分所用催化剂上发现了环戊硫酮中间产物。Ni和Mo对反应具有协同作用 ,Ni的加入明显加速了第二步反应的进行 ,使反应活性和选择性大大提高更多还原

【Abstract】 The thiolation of cyclopentanone into cyclopentanethiol was investigated over alumina supported unpromoted and a series of Ni promoted Mo catalysts. It was confirmed that a two step reaction scheme was involved in the reaction with a thioketone acting as the reaction intermediate by the detection of cyclopentanethione over both Ni free and Ni bearing catalysts with low Ni contents. It was also revealed that the role of Ni was to accelerate the reaction step of hydrogenation of cyclopentanethione into cyclopentanethiol.更多还原
