Propionaldehyde or
propanal is the
organic compound with the formula CH
3CH
2CHO. It is a saturate 3-carbon
aldehyde and is a
structural isomer of
acetone. It is a colourless liquid with a slightly irritating, fruity odour.
Propionaldehyde is mainly produced through the
hydroformylation, by combining
synthesis gas (
carbon monoxide and
hydrogen) with
ethylene using a metal
catalyst:
» CO + H
2 + C
2H
4 → CH
3CH
2CHO
Uses
It is principally used as a precursor to "trimethylolethane" (CH
3C(CH
2OH)
3) through a
condensation reaction with
methanol; this triol is an important intermediate in the production of
alkyd resins.
Condensation of propionaldehyde with
tert-butylamine gives CH
3CH
2CH=N-
t-Bu, a three-carbon building block used in
organic synthesis. Deprotonation of this
imine with
LDA produces CH
3CHLiCH=N-
t-Bu, which in turn condenses with
aldehydes.
