Benzotrichloride Usage And Synthesis
  • Chemical Propertiescolourless liquid
  • Chemical PropertiesBenzotrichloride is a combustible, colorless to yellow-brown, oily liquid that fumes on contact with air. It has a penetrating odor.
  • Usesα,α,α-Trichlorotoluene was used in determination of chlorinated toluenes in effluents of wastewater treatment plants and textile industries by closed loop stripping analysis.
  • UsesIn dye chemistry. In organic syntheses (source of benzenyl group).
  • UsesChemical intermediate primarily in benzoyl chloride production; dye intermediate
  • General DescriptionA clear colorless to yellowish colored liquid with a penetrating odor. Denser than water and vapors are heavier than air. May be toxic by inhalation or ingestion. Burns skin, eyes, and mucous membranes. Insoluble in water. Used to make dyes and other chemicals.
  • Air & Water ReactionsHydrolyzes in the presence of moisture. The reaction is rather slow due to low solubility in water.
  • Reactivity ProfileBenzotrichloride hydrolyzes in the presence of moisture. Benzotrichloride reacts with water, lime, ammonia, strong alkalis, organic amines, chlorates and acids.
  • HazardHighly toxic by inhalation, fumes highly irritant. Eye, skin, and upper respiratory tract irri- tant. Probable carcinogen.
  • Health HazardToxic by inhalation; fumes are highly irritating to skin and mucous membranes. May cause death or permanent injury after very short exposure to small quantities. A suspected carcinogen.
  • Fire HazardBenzotrichloride may react violently with water. Fire may produce irritating or poisonous gases. Flammable/poisonous gases may accumulate in tanks and hopper cars. Materials may ignite combustibles (wood, paper, oil, etc.). Produces toxic and corrosive fumes when Benzotrichloride reacts with water or steam. Similar to hydrochloric acid; material will react with water or steam to produce toxic and corrosive fumes. Hydrolyzes in presence of water forming benzoic and hydrochloric acids.
  • Potential ExposureBenzotrichloride is used as a chemical and dye intermediate; extensively used in the dye industry for the production of Malachite green, Rosamine, Quinoline red, and Alizarin yellow A. It can also be used to produce ethyl benzoate. Commercial grades may contain hydrochloric acid, benzylidene chloride, or benzyl chloride.
  • CarcinogenicityBenzotrichloride is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
  • ShippingUN2226 Benzotrichloride, Hazard class: 8; Labels: 8—Corrosive material.
  • IncompatibilitiesBenzotrichloride decomposes on heating, on contact with acids and/or water, producing toxic and corrosive hydrogen chloride and benzoic acid. Reacts violently with strong oxidizers, iron and other metals, alkali and earth alkali metals; bases and organic substances, and may cause fire and explosions. On contact with air it emits toxic and corrosive hydrogen chloride. Attacks many metals in presence of water. Attacks many plastics.
  • Waste DisposalIncineration with flammable solvent added in incinerator with afterburner and alkaline scrubber.
