Product Name:N,N'-Di(1-naphthyl)-p-phenylenediamine
English Name:N,N'-Di(1-naphthyl)-p-phenylenediamine
CAS No.:395-25-5
Aliases:Antioxidant, Rubber antioxidant, N,N'-Bis(1-naphthyl)-1,4-phenylenediamine
Molecular Formula:C26H20N2
Physical Properties:Gray to gray-brown powder. Melting point approximately 225–230 °C, relative density about 1.2. Soluble in organic solvents such as benzene, toluene, acetone and chloroform; slightly soluble in ethanol; insoluble in water. Exhibits excellent resistance to thermal-oxidative aging and can inhibit the catalytic aging effect of metal ions such as copper and manganese on rubber.
Uses:Used as an antioxidant for natural rubber, styrene-butadiene rubber, nitrile rubber, chloroprene rubber and other rubbers. It improves resistance to thermal-oxidative aging and flex fatigue, and is suitable for rubber products used at high temperatures or in contact with metals.
Technical Specifications:
Melting point: approximately 225–230 °C
Appearance: gray to gray-brown powder
Solubility: soluble in benzene, acetone and chloroform; insoluble in water
Assay (HPLC): ≥98%
Loss on heating: ≤0.5%
