摘要
本文用分光光度法测定了对氯偶氮氯膦试剂的质子化常数和逐级离解常数;并运用量子化学计算结果阐释其质子化与离解作用的微观机理。
The protonation and dissociation of chlorophosphonazo-p-C1 in aqueous solution have been studied spectrophotometrically.The protonation constant is log K_p=-1.06 and the dissociation constants are 0.40, 1.37. 2.57, 6.75, 9.54 and 11.59 for pK_1, pK_2, pK_3, pK_4, pK_5 and pK_6 respectively. Microcosmic mechanism of protonation and dissociation of the reagent are interpreted by calculation with quantum chemistry.
