• Pulp and Paper Processing [Category: Industry]
• Leather Tanning and Processing [Category: Industry]
• Intermediate in the preparation of triphenyl methane and related dyes, organic intermediate. /Chlorobenzaldehyde/
• 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.
