grey powder용도
Polymerization inhibitor. Antioxidant for rubber, petroleum oils, feedstuffs.정의
ChEBI: An N-substituted diamine that is 1,4-phenylenediamine in which one hydrogen from each amino group is replaced by a phenyl group.일반 설명
Gray or dark gray powder or flakes.공기와 물의 반응
Insoluble in water.반응 프로필
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.화재위험
N,N-Diphenyl-p-phenylenediamine is combustible. N,N-Diphenyl-p-phenylenediamine may form explosive dust-air mixtures.색상 색인 번호
A rubber accelerant, formerly contained in “blackrubber mix.” The most frequent occupational categories are in the metal industry, homemakers, health services and laboratories, and the building industry.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.]N,N'-다이페닐-파라-페닐렌다이아민 준비 용품 및 원자재
