范文编号:ZY105 范文字数:9904,页数:25 摘 要: 构造了11种不同结构的(Salen)Co(Ⅲ)催化剂,采用HyperChem软件对其前线轨道能级进行了计算,将计算结果与其催化水解动力学拆分环氧氯丙烷反应所得的活性数据相比较,研究不同平衡离子的(Salen)Co(Ⅲ)催化剂的微观结构(EHOMO)和催化活性(反应速率)之间的关系,对(Salen)Co(Ⅲ)催化剂的EHOMO和反应时间的数值拟合,建立了相应的构效关系式,发现(Salen)Co(Ⅲ)催化剂的EHOMO越低,其催化活性越高,且呈一定的线性关系。 关键词:(Salen)Co(Ⅲ)催化剂;量子化学;轨道能级;理论研究 Abstract: Constructed 11 different configuration of (Salen)Co(III) activator,used the HyperChem software to calculate the frontier orbital energy, then compared the result with the date of hydrolytic kinetic resolution (HKR),investigated the relationship between the EHOMO and the reaction time with the different configuration of (Salen)Co(III) activator, it was found that there was excellent linear correlation between catalytic activity and frontier orbital energy, if the EHOMO was lower, the recation time was more.
