純化方法

Convert lauraldehyde to the bisufite addition compound by shaking with saturated aqueous NaHSO3 for 1hour. The precipitate is filtered off, washed with ice cold water, EtOH and ether, then decomposed with aqueous Na2CO3. The aldehyde is extracted into diethyl ether which, after drying and evaporating, gives an oil which is fractionally distilled under vacuum. [Beilstein 1 IV 3380.]
