Product description
It is white to purple red crystal. It will turn purple red or dark brown when exposure to the air. It can be dissolved in water, alcohol, ether, chloroform and benzene. p-Phenylenediamines are white to slightly red crystalline solids. They have been described as gray “light brown” which may result from exposure to air. ChEBI: A phenylenediamine in which the amino functions are at positions 1 and 4 of the benzene nucleus.
Applicable Fields
Dyeing
This compound is a common hair dye. Its use is being supplanted by other aniline analogues and derivatives such as 2,5-diamino(hydroxyethylbenzene and 2,5-diaminotoluene. Other popular derivatives include tetraaminopyrimidine and indoanilines and indophenols. Derivatives of diaminopyrazole give red and violet colours. In these applications, the nearly colourless dye precursor oxidizes to the dye.
Precursor to polymers
PPD is a precursor to aramid plastics and fibers such as Kevlar. These applications exploit PPD's difunctionality. This polymer arises from the reaction of PPD and terephthaloyl chloride. The reaction of PPD with phosgene gives the diisocyanate, a precursor to urethane polymers.
Rubber antioxidant
PPD is easily oxidized, and for this reason derivatives of PPD are used asantiozonants in production of rubber products. The substituents, naphthyl, isopropyl etc affect the effectiveness of their antioxidant roles as well as their properties as skin irritants
