释义 | butyraldehydeenUKbu·tyr·al·de·hydeB0586400 (byo͞o′tə-răl′də-hīd′)butyraldehyde(ˌbjuːtɪˈrældɪˌhaɪd)bu•tyr•al•de•hyde(ˌbyu təˈræl dəˌhaɪd)n. ButyraldehydeenUKbutyraldehyde[¦byüd·ər′al·də‚hīd]Butyraldehydea 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. |
