MSDS Information

• 3,3'-Dichlorobenzidine

4,4'-ビ[2-クロロアニリン] 化学特性,用途語,生産方法

• 用途

  有機黄色顔料(ベンジジンエローG?GR、バルカン、ファストエローG,パーネントエローHR等)の中間物

• 化学的特性

  colourless to white crystalline solid

• 物理的性質

  Colorless to grayish-purple needles or crystals with a mild or pungent odor

• 使用

  Intermediate in the manufacture of azo dyes and pigments for printing inks, textiles, paints, plastics, and crayons; curing agent for isocyanate-terminated polymers and resins; rubber compounding ingredient; analytical determination of gold; formerly used as chemical intermediate for direct red 61 dye.

• 一般的な説明

  Gray to purple crystalline powder. Insoluble in water. Very toxic. Used in the dye industry, curing agent for isocyanate terminated resins.

• 空気と水の反応

  Insoluble in water.

• 反応プロフィール

  A halogenated amine. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.

• 健康ハザード

  3,3'-Dichlorobenzidine (DCB) is carcinogenic in several animal species.

• 火災危険

  Combustible.

• 安全性プロファイル

  Confirmed carcinogen with experimental carcinogenic and tumorigenic data. Human mutation data reported. When heated to decomposition it emits very toxic fumes of Cl and NOx.

• 職業ばく露

  A halide-and amine-substituted aromatic compound used in the dye industry, curing agent for isocyanate terminated resins. The major uses of dichlorobenzidine are in the manufacture of pigments for printing ink, textiles, plastics, and crayons and as a curing agent for solid urethane plastics. There are no substitutes for many of its uses. Additional groups that may be at risk include workers in the printing or graphic arts professions handling the 3,3’-DCB-based azo pigments. 3,3’-DCB may be present as an impurity in the pigments, and there is some evidence that 3,3’-DCB may be metabolically liberated from the azo pigment

• 発がん性

  Studies in several test systems have shown DCB to be genotoxic in vitro and in vivo and suggest that this effect most likely mediates the carcinogenicity of the chemical. In vitro, DCB has induced sister chromatid exchanges, unscheduled DNA synthesis, and positive responses in bacterial Salmonella assays; in vivo DCB induced micronuclei in polychromatic erythrocytes in male mice and fetuses.
  Because of demonstrated potent carcinogenicity in multiple animal species, evidence of genotoxicity, and structural relationship to the known bladder carcinogen benzidine, DCB should be regarded as a probable human carcinogen and exposure by any route should be avoided.
  3,3￠-Dichlorobenzidene has no threshold limit value (TLV) exposure limit and is classified as an A3, confirmed animal carcinogen with unknown relevance to humans, and a notation for skin absorption.

• 輸送方法

  UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required

• 純化方法

  Crystallise the benzidine from EtOH, pet ether (m 133o) or *benzene. [Beilstein 13 H 234, 13 I 67, 13 II 106, 13 III 477, 13 IV 384.] CARCINOGEN.

• 不和合性

  Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, and epoxides. Achemical base: neutralize acids to form salts plus water with an exothermic reaction. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generatedby amines in combination with strong reducing agents such as hydrides, nitrides, alkali metals, and sulfides.

• 廃棄物の処理

  Incineration (816C, 0.5 second for primary combustion; 1204C, 1.0 second for secondary combustion). The formation of elemental chlorine can be prevented through injection of steam ormethane into the combustion process. nitrogen oxides may be abated through the use of thermal or catalytic devices. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal
