描述: Dye intermediates are essential chemical building blocks, primarily derived from petroleum downstream products like benzene, toluene, and naphthalene, used to synthesize finished dyes and pigments. These, including aniline and various derivatives, undergo reactions such as sulfonation, nitration, and reduction to define a dye's color, solubility, and performance. They are crucial for industries like textiles, plastics, paints, and inks.
