【摘要】 本文在25±1℃条件下用平衡分配法考察了吡啶（B）在HDHP—苯——（Na,H）ClO₄体系中的分配行为,测得萃取平衡为■其中K_ex,1,2=10^2·34。萃取反应类似于中性络合反应。据文献[6]的数据,求得反应的生成常数β_1,2（0）=10^1·03。其中B:表示未质子化的吡啶, H₂A₂:l表示HDEHP=聚分子, a,0:分别表示水相和有机相。更多还原

【Abstract】 The extraction behaviour of pyridine （B） in the system of HDEHP-C₆H₆ —（Na, H） ClO₄ has been studied by means of the partition method. The extraction equilibrium was found to be as follows:where K_（?）2=10^2·34. The extraction reaction might be similar to the neutral complexation. From the data reported in reference[6], the formation constant of B（H₂A₂）_2（0） in the organic phase was obtained to be 10^1·93.更多还原
