p-Phenylenediamine CAS 106-50-3

short description:

p-Phenylenediamine (English p-Phenylenediamine), also known as Ursi D, is one of the simplest aromatic diamines. The pure product is white to lavender crystals, which turns purple or dark brown when exposed to the air.
color. 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. It is mainly used for aramid, azo dyes, sulfur dyes, acid dyes, and can also be used as fur black D. Production of Mao Pi Black DB, Mao Pi Brown N2, and Chemicalbook 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.
It is obtained by reducing p-nitroaniline with iron powder in acidic medium. Put the iron powder into hydrochloric acid, heat it to 90°C, and add p-nitroaniline while stirring. After the addition is completed, react at 95-100°C for 0.5h, and then add concentrated hydrochloric acid dropwise to complete the reduction Chemicalbook reaction. After cooling, neutralize with saturated sodium carbonate solution to pH 7-8, boil and filter while hot, and wash the filter cake with hot water. Combine the filtrate and washing liquid, concentrate under reduced pressure, crystallize by cooling or distill under reduced pressure to obtain p-phenylenediamine with a yield of 95%.
