Chemical Name:N,N'-Di-beta-naphthyl-p-phenylenediamine
Molecular Formula:C26H20N2
Molecular Weight:360.46
Structural Formula:
CAS:93-46-9
Technical Indicators:
Index Name | Firsts | Qualified product |
Appearance(eye measurement) | Dustcolor crystalline powder | |
Incipient melting point oC | ≥225.0 | ≥225.0 |
Heating loss % ß-naphthyl's Content | ≤0.40 ≤0.40 | ≤0.50 ≤0.40 |
Ash content % | ≤0.40 | ≤0.50 |
Residue on sieve(150µm),% | ≤0.0 | ≤0.1 |
Properties:The pure product is tinted bright laminated shape crystal, is easy to dissolve in the hot aniline and the nitrobenzene, may dissolve in the hot ethanoic acid, is not easy to dissolve in the benzene, the ethyl acetate, the acetone, the ethyl alcohol and the ether. The long-term exposure, its color may turn dull red gradually and its potency declines, poisonous.
Main Uses:This product is the natural rubber and synthetic rubber and its rubber latex's antioxidant. Has the good protection to the hot oxygen aging and the static exposure, can effectively protect the copper and manganese harms. The anti- ultraviolet ray aging effect is remarkable in the butylbenzene rubber, the chloroprene rubber rubber coated fabric products may improve the rubber coated fabric products's harden phenomenon. Used in the electric wire, the electric cable, the tire, the rubber latex product and so on.
