BENZAL CHLORIDE Usage And Synthesis
- Chemical Propertiescolourless oily liquid
- Chemical PropertiesBenzal chloride is a combustible, fuming, colorless, oily liquid; fumes on exposure to air. Faint, pungent odor.
- Usesα,α-Dichlorotoluene has been useds as initiator during the atom transfer radical polymerization (ATRP) of styrene and methyl methacrylate.
- Usesmanufacture of benzaldehyde, cinnamic acid.

- General DescriptionA 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 ReactionsInsoluble in water.
- Reactivity ProfileBENZAL 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). .
- HazardStrong irritant and lachrymator. Probable carcinogen.
- Health HazardAcute: vapors are highly irritating to eyes. May be fatal if inhaled, swallowed, or absorbed through skin.
- Fire HazardFire 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 ProfileConfirmed 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 ExposureBenzal chloride is used almost exclusively for the manufacture of benzaldehyde. It can also be used to prepare cinnamic acid and benzoyl chloride.
- ShippingUN1886 Benzylidene chloride, Hazard class 6.1; Label 6.1—Poisonous materials.
- IncompatibilitiesMay 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 DisposalIncineration @ 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.
