English another name: N, N-diphenyl-p-phenylenediamine

English abbreviation: DPPD

CAS RN: 74-31-7

1. Physical and chemical properties:

1.1 Molecular formula: C18H16N2

1.2 Molecular weight: 260.34

1.4 Specific gravity: 1.2

1.5 Solubility: Dissolve in benzene, toluene, ether and acetone. Dissolve slightly in ethanol. Insoluble in water.

1.6 Boiling point: 220-225℃, 0.5mmHg

1.7 Stability and reactivity: Flammable. When it’s exposed to air or sunlight, the product will be oxidized and change its color. When contacted with hot dilute hydrochloric acid, it becomes green.

3. Uses: It can be used as the antioxidant in solid propellant to improve the storage stability of the product. It has been used for those natural, styrene-butadiene, acrylonitrile-butadiene, butadiene, butyl, hydroxyl, polyisoprene rubber to possess performance such as good flex life and crazing for enhancing the tensile modulus, strengthening the defending function to hot-oxygen , ozone and some harmful metals such as copper, manganese with not influence on vulcanization of those rubbers. It can resolve aging problem existing in the deep-color rubber products while antioxidant H is used together with antioxidant D. Moreover, it can be also used as the hot-oxygen stabilizer for those engineering plastics such as polyethylene, polypropylene, polyamide, polyformaldehyde and etc to improve their climate-resisting performance. The reference dosage is 0.2-0.3%.
