Description:
Aminophenol is also called hydroxyaniline and aminohydroxybenzene. There are 3 isomers, namely o-aminophenol, m-aminophenol, p-aminophenol. In 1874, Baeyer et al first prepared p-aminophenol. Due to the different relative positions of hydroxyl and amino groups, the three are also different in physicochemical properties. This product is weakly alkaline, weakly acidic and strongly reducing. Because it has two groups of amino group and phenol at the same time, it has the commonality of both. Very unstable in air and sunlight, especially sensitive to oxygen in humid air, especially the ortho and para positions are more easily oxidized to deepen the color, mainly to generate aminophenoxazine derivatives after oxidation.
