Description
2-Methyloctanal has a delicate, floral odor (rose- or lily-like).
Prepared by heating methoxymethyl hexyl carbinol with oxalic
acid or with anhydrous formic acid; also from hexanal and propionic
aldehyde, Darzen’s synthesis of reacting methyl hexyl ketone
and ethyl chloroacetate with sodium ethylate; the resulting ester
is then hydrolyzed to the acid and this heated under vacuum.
