Abstract

Organic nonelectrolytes can be selectively transported through an ion-exchange membrane if they are specifically converted to electrolytes in the membrane. Aldehydes react with bisulfite to form hydroxyalkanesulfonates (HASA), which are the conjugate bases of strong acids. Aldehydes are shown to be transported efficiently across an anion-exchange membrane via the coupled counter-transport of HMSA ion with hydroxide ion and the relay of an aldehyde from one membrane-bound bisulfite ion to another. Permeation rates are in the order of formaldehyde > acetaldehyde > acetone; this relationship parallels the relative order of the stability constants for formation of the respective adducts with bisulfite ion. Aldehydes can be separated readily from other organic solutes by this method.
