Dyestuff Intermediates, commonly referred to as intermediates, encompass a diverse array of aromatic derivatives employed in the synthesis of dyes and organic pigments. These intermediates are manufactured using benzene, toluene, and other aromatic compounds sourced from the coal chemical and petrochemical sectors. The production process involves a sequence of organic synthesis units.

Dyestuff Intermediates Categories

Dyestuff Intermediates can be divided into four categories: benzene intermediates, toluene intermediates, naphthalene intermediates and anthraquinone intermediates, as well as some heterocyclic intermediates. 

The most important dyestuff intermediates are o-nitrochlorobenzene, p-nitrochlorobenzene, o-nitrotoluene, p-nitrotoluene, 2-naphthol, anthraquinone, 1-aminoanthraquinone and so on. Various intermediates with complex structures can be prepared from these intermediates through a series of organic synthesis unit processes.
