Introduction and property
Introduction
P-Phenylenediamine (English p-Phenylenediamine), also known as Ursi D, is one of the simplest aromatic diamines. The pure product is white to lavender crystal, which turns purple or dark brown when exposed to the air. Slightly soluble in cold water, soluble in ethanol, ether, chloroform and benzene. It can be used to prepare azo dyes, high molecular polymers, and can also be used to produce fur dyes, rubber antioxidants and photo developers Chemicalbook. It is mainly used for aramid, azo dyes, sulfur dyes, acid dyes, and can also be used for fur. Production of black D, fur blue black DB, fur brown N2, and rubber antioxidants DNP, DOP, and MB. It is also used as raw material for cosmetic hair dye Ursi D series, gasoline polymerization inhibitor and developer. As a chemical dye, p-phenylenediamine is currently allowed to be used in the production of hair dyes, but there are clear restrictions on the amount of use.
