    用于杂芳盐和离子液体的简单卤化物阴离子交换方法
    摘要:
    一种广泛而简单的方法允许在非水介质中使用阴离子交换树脂(A-型)将季杂芳烃和铵盐中的卤离子交换为各种阴离子。使用两种不同的阴离子源(酸或铵盐)并改变溶剂的极性来检查 AER(OH- 形式)的阴离子负载。然后将有机溶剂中的 AER(A-形式)方法应用于几种季杂芳族盐和离子液体,阴离子交换以优异的定量收率进行,同时去除卤化物杂质。依靠目标离子对的疏水性进行反阴离子交换,使用具有可变极性的有机溶剂,如 CH3OH、CH3CN 和偶极非羟基溶剂混合物 CH3CN:CH2Cl2 (3:

    Comparison between phosphine and NHC-modified Pd catalysts in the telomerization of butadiene with methanol – A kinetic study combined with model-based experimental analysis
    摘要:
    The telomerization of butadiene with methanol was investigated in the presence of different palladium catalysts modified either with triphenylphosphine (TPP) or 1,3-dimesityl-imidazol-2-ylidene (IMes) ligand. When pure butadiene was used as substrate, a moderate selectivity for the Pd-TPP catalyst toward the desired product 1-methoxy-2,7-octadiene (1-Mode) of around 87% was obtained, while the IMes carbene ligand almost exclusively formed 1-Mode with 97.5% selectivity. The selectivity remained unchanged when the pure butadiene feed was replaced by synthetic crack-C-4 (sCC(4)), a technical feed of 45 mol% butadiene and 55 mol% inerts (butenes and butanes). The TPP-modified catalyst showed a lower reaction rate, which was attributed to the expected dilution effect caused by the inerts. Surprisingly, the IMes-modified catalyst showed a higher rate with sCC(4) compared to the pure feed. By means of a model-based experimental analysis, kinetic rate equations could be derived. The kinetic modeling supports the assumption that the two catalyst systems follow different kinetic rate equations. For the Pd-TPP catalyst, the reaction kinetics were related to the Jolly mechanism. In contrast, the Jolly mechanism had to be adapted for the Pd-IMes catalyst as the impact of the base seems to differ strongly from that for the Pd-TPP catalyst. The Pd-IMes system was found to be zero order in butadiene at moderate to high butadiene concentrations and first order in base while the nucleophilicity of the base is influenced by the methanol amount resulting in a negative reaction order for methanol.
