Heptaldehyde is used as a predecessor to various intermediates and chemical compounds such as heptyl
alcohol and heptonoic acid, which are subsequently used in various industries.
The O-alkyl (2-18) derivatives were obtained in high yields on refluxing a solution of 1 in 4% methanolicNaOH with alkyl halides (ethyl bromide, butyl bromide, isobutyl bromide, pentyl bromide, hexyl bromide, heptyl
chloride, octyl bromide, nonyl chloride, decyl chloride, allyl bromide, benzyl chloride, 2-iodobenzyl bromide, 3-iodobenzyl bromide, 4-iodobenzyl bromide, 2-nitrobenzyl bromide, 3-nitrobenzyl bromide and 4-nitrobenzyl bromide) and work up.
All these catalysts are applied for the catalytic esterification of acetic acid with heptanol to produce heptyl
