摘要: 本文应用分光光度法及量子化学方法,研究了7-(2-吡啶偶氮)-8-羟基喹啉在溶液中的酸碱平衡及其存在形式。测定了在有无表面活性剂存在下,试剂的离解常数。互变异构平衡的研究指出,加入有机溶剂使异构平衡向偶氮型方面移动,在表面活性剂存在下,平衡向醌型方面移动。

Abstract: The dissociation constants of PAOx were determined spectrophotometrically in the presence or absence of surfactants.The state of PAOx in aqueous solutions was studied by using spectrophotometric and quantum chemical methods.The tautome-tric equilibrium is shifted to the quinone-hydrazone form in the presence of CTMAB.
