在测定一系列具长碳链一元烷基磷(膦)酸pK_a值的基础上,求得十八个烷基及烷氧基的σ~p常数,并首次讨论与确定了σ~p值与基团连通性参数之间的关系.这些长碳链烷基及烷氧基σ~p值的求得有助于研究酸性磷(膦)酸酯萃取金属反应的结构-性能定量关系.
Based on the determination of a series of pK_a values of long chain carbon monobasic alkylphosphoric (phosphonic) acids, the σ ~ p constants of eighteen alkyl and alkoxy groups were calculated and discussed for the first time. Group connectivity parameters of these long carbon chain alkyl and alkoxy σ ~ p values obtained help to study the acidic phosphorus (phosphine) ester metal extraction reaction-structure-property relationship.
