2-Chlorobenzaldehyde Chemical Properties,Uses,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.]
