Description
Methyl nonanoate has a wine and coconut-like odor. Below
10 ppm, it has a sweet, coconut-like flavor. May be synthesized
by heating pelargonic acid with methyl alcohol in the presence of
concentrated sulfuric acid and subsequent rectification; or by
hydrogenation of 1,5-octadien-carboxylic acid methyl ester using
palladium chloride in methanol solution.
