Chemische Eigenschaften
3,3’-Dichlorobenzidine is a gray or purple crystalline solid.
Chemische Eigenschaften
beige to tan powder
Verwenden
3,3'-Dichlorobenzidine Dihydrochloride, is structurally similar to Benzidine (B121000), and thus is considered a carcinogen. It can be used in the production of azo dyes. Dyes and metabolites, Environmental Testing
Allgemeine Beschreibung
Light tan powder.
Air & Water Reaktionen
Insoluble in water.
Reaktivität anzeigen
3,3'-Dichlorobenzidine dihydrochloride reacts as a weak acid. May react vigorously with strong oxidizing agents. May generate flammable gases with strong reducing agents.
Brandgefahr
Flash point data for 3,3'-Dichlorobenzidine dihydrochloride are not available but 3,3'-Dichlorobenzidine dihydrochloride is probably combustible.
Flammability and Explosibility
Non flammable
Sicherheitsprofil
Confirmed carcinogen. Moderately toxic by ingestion. Mutation data reported. When heated to decomposition it emits very toxic fumes of Cl and NOx.
mögliche Exposition
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

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