3,4-자일리딘 C화학적 특성, 용도, 생산
화학적 성질
slightly beige to beige or pink crystalline mass용도
3,4-Dimethylaniline is used to study electron donor-acceptor interaction with DCNQ. It is also used as a fine chemical &organic intermediate.정의
ChEBI: A primary arylamine that is aniline in which the hydrogens at the 3- and 4-positions are replaced by methyl groups. A low-melting, crystalline solid, it is used in the production of vitamin B2, dyes, pesticides and other chemicals.일반 설명
Pale brown crystals or off-white solid.공기와 물의 반응
3,4-Dimethylaniline may be sensitive to prolonged exposure to air. Insoluble in water.반응 프로필
3,4-Dimethylaniline ignites on contact with fuming nitric acid . 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
3,4-Dimethylaniline is combustible.Safety Profile
Suspected carcinogen. Poison by ingestion. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx. See also other xylidine entries.Purification Methods
Crystallise it from ligroin and distil it under vacuum. [Beilstein 12 H 1103, 12 IV 2502.]3,4-자일리딘 준비 용품 및 원자재
