butyraldehyde [¦byüd·ər′al·də‚hīd]
(organic chemistry) CH3(CH2)2CHO A colorless liquid boiling at 75.7°C; soluble in ether and alcohol, insoluble in water; derived from the oxo process. Butyraldehyde a saturated aliphatic aldehyde; a colorless liquid with a sharp, unpleasant odor, readily soluble in organic solvents but exhibiting only limited solubility in water. Butyraldehyde has two known isomers: n-butyr aldehyde, or butanal, CH3CH2CH2CHO (boiling point, 74.8°C; density, 0.802 g/cm3 at 20°C), and isobutyraldehyde, or isobutanal, (CH3)2CHCHO (boiling point, 64°C; density, 0.794 g/cm3 at 20°C). The η-butyraldehyde is of practical value in the preparation of polyvinylbutyral, which is widely used in the manufacture of laminated safety glass, BF adhesives, varnishes, and enamels. The commercial production of n-butyraldehyde usually involves the reduction of crotonaldehyde. Less often, it is produced by the dehydrogenation of n-butanol or the oxidation of n- butane.
