| 摘 要： | 盐酸付玫瑰苯胺是三苯甲烷类染料，分子中存在的共轭体系使其具有以下特性：１．本身带色；２．随介质的ｐＨ变化产生显著的颜色效应，ｐＨ值越高，颜色越深，ｐＨ值越低，颜色越浅；３．对光和水洗的坚牢度较差；４．可发生重氮化反应；５．杂质使其颜色加深。

| Abstract: | Pararosaniline hydrochloride is a kind of triphenyl methane dye. Because of molecular conjugate system, it has the following characteristics 1. coloaration; 2. producing significant colouration effect with PH changes of medium; 3. inferior sunfastness and washfastness; 4.having overlapping nitrogen reaction and 5. deep colousation caused by impurity. |
