摘要: 对氨基偶氮苯(简称p-AAB)及其盐酸盐(简称p-AAB·HCl),是一有机中间体,又是有机试剂。有关它的含量测定,目前生产上缺少一适当的方法。p-AAB是芳伯胺,若用重氮化或非水酸碱滴定。

Abstract: The method is based on the reaction of sodium sulfide and formaldehyde with the determined compound in hydrochloric acid solution,forming a purplish-red colour solution. It was measured at λmax515 nm by spectrophotometry.
