Heptanal or heptanaldehyde is an alkyl aldehyde. It is a colourless liquid with a strong fruity odor, which is used as precursor to components in perfumes and lubricants. [2 ] Production [edit ]
It can be obtained from
castor oil by distillation under reduced pressure. It is synthesized by degradation of the esters of [1 ] ricinoleic acid. It is also prepared by hydroformylation of hexene. [2 ] Uses [edit ]
Industrially, it is used in the manufacture of α-amylcinnamaldehyde, a component of many fragrances.
It is the precursor to [2 ] 1-heptanol and ethyl heptanoate, the latter being a component of certain lubricants.
