N,N-Diphenyl-p-phenylenediamine Usage And Synthesis
DescriptionN,N'-Diphenyl-4-phenylenediamine (DPPD) is a rubber accelerant, formerly contained in the "black rubber mix". The most frequent occupational categories are in metal industry, homemakers, health services and laboratories, and building industries.
Chemical Propertiesgrey powder
UsesPolymerization inhibitor. Antioxidant for rubber, petroleum oils, feedstuffs.
UsesN1,N4-Diphenylbenzene-1,4-diamine can be used to prepare low pressure change, high temperature resistant flame retardant silicone rubber.
UsesN,N'-Diphenyl-4-phenylene diamine is an antioxidant for rubber, petroleum oils, and feed stuffs; stabilizer; a polymerization inhibitor; used to retard copper degradation; as an intermediate for dyes, drugs, plasties and detergents; antidegradant for nitrile-butadiene rubber, natural, styrene-butadiene, isoprene, butadiene, and ehloroprene rubbers.
DefinitionChEBI: An N-substituted diamine that is 1,4-phenylenediamine in which one hydrogen from each amino group is replaced by a phenyl group.
General DescriptionGray or dark gray powder or flakes.
Air & Water ReactionsInsoluble in water.
Reactivity ProfileN,N-Diphenyl-p-phenylenediamine may react with oxidizing materials . Neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
Fire HazardN,N-Diphenyl-p-phenylenediamine is combustible. N,N-Diphenyl-p-phenylenediamine may form explosive dust-air mixtures.
Contact allergensA rubber accelerant, formerly contained in “blackrubber mix.” The most frequent occupational categories are in the metal industry, homemakers, health services and laboratories, and the building industry.
Purification MethodsCrystallise the diamine from EtOH, chlorobenzene/pet ether or *benzene. It has also been crystallised from aniline, then extracted three times with absolute EtOH. [Beilstein 13 H 80.]
