ABSTRACT:
A process for the isolation of n-aldehyde from a mixture of n-aldehyde and i-aldehyde in a solvent by the addition of no more than a stoichiometric amount of an alkali metal hydrogen sulfite in aqueous solution to the mixture. The resulting precipitate is separated, washed, and later decomposed to yield substantially pure n-aldehyde.
