BENZAL CHLORIDE Chemical Properties,Uses,Production
Description
Benzal chloride (dichloromethylbenzene, a,adichlorotoluene, benzylidene chloride) is produced exclusively by the side-chain chlorination of toluene. It was first synthesized in 1848 by A. CAHOURS, by using the reaction of PCl5 with benzaldehyde. Almost the sole application of benzal chloride is in the production of benzaldehyde.
Chemical Properties
Benzal chloride is a combustible, fuming, colorless, oily liquid; fumes on exposure to air. Faint, pungent odor.
Physical properties
Benzal chloride is a liquid which fumes in moist air and which has a pungent odor and a strong irritant effect on the mucous membranes and eyes.Benzal chloride is freely soluble in alcohol, ether, chloroform, and carbon tetrachloride, but only slightly soluble in water (0.05 g/L at 5 ℃; 0.25 g/L at 39 ℃). The solubility of chlorine in 100 g of benzal chloride is 6.2 g at 30 ℃, 4.3 g at 50 ℃, 1.5 g at 100 ℃.
Uses
α,α-Dichlorotoluene has been useds as initiator during the atom transfer radical polymerization (ATRP) of styrene and methyl methacrylate.
General Description
A colorless oily liquid with a faint aromatic odor. Insoluble in water and denser than water. Strongly irritates skin and eyes. Used to manufacture dyes.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
BENZAL CHLORIDE is incompatible with strong oxidizers and strong bases. BENZAL CHLORIDE readily hydrolyzes under acid or alkaline conditions. BENZAL CHLORIDE reacts with metals (except nickel and lead). .
Hazard
Strong irritant and lachrymator. Probable carcinogen.
Health Hazard
Acute: vapors are highly irritating to eyes. May be fatal if inhaled, swallowed, or absorbed through skin.
Fire Hazard
Fire may produce irritating or poisonous gases. Runoff from fire control water may give off poisonous gases and may cause pollution. Cylinder may explode in the heat of fire. Reacts with water to release hydrochloric acid.
Safety Profile
Confirmed carcinogen with experimental carcinogenic and neoplastigenic data. Poison by inhalation. Moderately toxic by ingestion. A strong irritant and lachrymator. Causes central nervous system depression. Mutation data reported. When heated to decomposition it emits toxic fumes of Cl-. See also CHLORINATED HYDROCARBONS, AROMATIC.
Potential Exposure
Benzal chloride is used almost exclusively for the manufacture of benzaldehyde. It can also be used to prepare cinnamic acid and benzoyl chloride.
Shipping
UN1886 Benzylidene chloride, Hazard class 6.1; Label 6.1—Poisonous materials.
Incompatibilities
May form explosive mixture with air. Reacts with water, air, or heat, forming fumes of hydrochloric acid. Reacts (possibly violently) with acids, bases, strong oxidizers; many metals; potassium, sodium, aluminum. Attacks plastics and coatings.
Waste Disposal
Incineration @ 816 C, 0.5 second minimum for primary combustion; 1204 C, 1.0 second for secondary combustion; elemental chlorine formation may be alleviated through injection of steam or methane into the combustion process.
