2-Chlorobenzaldehyde Chemical Properties,Usage,Production

  • Chemical Properties colourless to brown liquid
  • Uses Acid zinc plating brightener, also be used for organic synthesis, agricultural pesticide and pharmaceutical industries.
    2-Chlorobenzaldehyde undergoes alkynylation with phenylacetylene in the presence of catalytic ligands and dimethylzinc at 0°C to form binaphthyl-derived amino alcohols.
    2-Chlorobenzaldehyde has been used in generation of small focused library of diversely functionalized dihydropyrimidine derivatives via one-pot three-component Biginelli cyclocondensation of β-ketoesters, aldehydes and thioureas.
  • Preparation 2-Chlorobenzaldehyde is produced mainly by chlorination of 2-chlorotoluene to form 2-chlorobenzal chloride, which is then subjected to acid hydrolysis. Metal salts, such as iron(III) chloride, are used as catalysts. The hydrolysis can also be accomplished using formic acid without a catalyst.
    2-Chlorobenzaldehyde can also be produced by oxidation of 2-chlorobenzyl chloride with N-oxides of tertiary amines or with dilute nitric acid.

  • General Description Clear colorless to yellowish liquid.
  • Air & Water Reactions 2-Chlorobenzaldehyde is moisture and light sensitive. Slightly water soluble.
  • Reactivity Profile 2-Chlorobenzaldehyde reacts with iron and strong oxidizers, strong bases and strong reducing agents.
  • Fire Hazard 2-Chlorobenzaldehyde is combustible.
  • Safety Profile Poison by intraperitoneal and intravenous routes. When heated to decomposition it emits toxic fumes of Cl-. See also ALDEHYDES and CHLORIDES.
  • Purification Methods Wash it with 10% Na2CO3 solution, then fractionally distil it in the presence of a small amount of catechol as stabiliser. [Beilstein 7 H 233, 7 IV 561.]
