摘要
以四(五氟化苯基)卟啉氯化铁(Ⅲ)为催化剂,在超临界丙烷中利用空气将丙烷高选择性地催化转化为异丙醇和正丙醇。研究发现,四(五氟化苯基)卟啉氯化铁(Ⅲ)在超临界丙烷中有着不同于液相反应的催化活性。考察了反应温度、反应时间、空气加入量和体系总压对反应的影响。结果说明,超临界丙烷中催化剂四(五氟化苯基)卟啉氯化铁虽然不如液相反应的转化数高,但是伯醇的选择性增加。反应后催化剂因氧化分解,需要进一步提高稳定性。
High selective oxidation of propane to n,i-propanol by air,with iron(Ⅲ) tetrakis(pentafluorophenyl)porphyrin as catalyst in super critical propane was investigated. Difference between catalytic reactions taking place in ordinary liquid phase and under super critical condition was illustrated.Effects of various reaction conditions,such as reaction time,reaction temperature,amount of air and system pressure were studied.During the reaction,serious decomposition of the catalyst was observed,thus,it is important to improve the stability of the catalyst.
