N,N-Diphenyl-p-phenylenediamine Usage And Synthesis
|
| Chemical Properties
|
grey powder
|
|
Description
|
N,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.
|
|
Uses
|
Polymerization inhibitor. Antioxidant for rubber, petroleum oils, feedstuffs.
|
| Uses
|
N1,N4-Diphenylbenzene-1,4-diamine can be used to prepare low pressure change, high temperature resistant flame retardant silicone rubber.
|
| Definition
|
ChEBI: An N-substituted diamine that is 1,4-phenylenediamine in which one hydrogen from each amino group is replaced by a phenyl group.
|
|
General Description
|
Gray or dark gray powder or flakes.
|
| Air & Water Reactions
|
Insoluble in water.
|
|
Reactivity Profile
|
N,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 Hazard
|
N,N-Diphenyl-p-phenylenediamine is combustible. N,N-Diphenyl-p-phenylenediamine may form explosive dust-air mixtures.
|
| Purification Methods
|
Crystallise 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.]
