Benzotrichloride Chemical Properties,Uses,Production

Chemical Properties

colourless liquid

Chemical Properties

Benzotrichloride is a combustible, colorless to yellow-brown, oily liquid that fumes on contact with air. It has a penetrating odor.


α,α,α-Trichlorotoluene was used in determination of chlorinated toluenes in effluents of wastewater treatment plants and textile industries by closed loop stripping analysis.


In dye chemistry. In organic syntheses (source of benzenyl group).

General Description

A 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 Reactions

Hydrolyzes in the presence of moisture. The reaction is rather slow due to low solubility in water.

Reactivity Profile

Benzotrichloride hydrolyzes in the presence of moisture. Benzotrichloride reacts with water, lime, ammonia, strong alkalis, organic amines, chlorates and acids.


Highly toxic by inhalation, fumes highly irritant. Eye, skin, and upper respiratory tract irri- tant. Probable carcinogen.

Health Hazard

Toxic 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 Hazard

Benzotrichloride 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 Exposure

Benzotrichloride 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.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. If victim is conscious, administer water or milk. Do not induce vomiting. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.


UN2226 Benzotrichloride, Hazard class: 8; Labels: 8—Corrosive material.


Benzotrichloride 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 Disposal

Incineration with flammable solvent added in incinerator with afterburner and alkaline scrubber.
