Product Name:N,N'-Diphenyl-1,4-phenylenediamine
English Name:N,N'-Diphenyl-1,4-phenylenediamine
CAS No.:74-31-7
Aliases:Antioxidant H, N,N'-Diphenyl-p-phenylenediamine, 1,4-Dianilinobenzene
Molecular Formula:C18H16N2
Physical Properties:Light gray to brown powder. Melting point approx. 144-145°C, boiling point approx. 220-225°C (0.5 mmHg), flash point approx. 204°C, refractive index 1.693, density approx. 1.2 g/cm³. Insoluble in water; soluble in acetone, benzene and other organic solvents.
Uses:Used as an antioxidant in natural rubber, styrene-butadiene rubber, nitrile rubber, polybutadiene rubber, butyl rubber, polyisoprene rubber and latex, giving products good flex resistance and crack resistance. It increases tensile modulus, enhances protection against thermal oxidation, oxygen, ozone and harmful metals such as copper and manganese, and has no effect on vulcanization. When used with antioxidant D, it solves a variety of aging problems of dark-colored rubber products; it is also used as a stabilizer for polyolefins such as polyethylene and polypropylene.
