ABSTRACT:
Aqueous solutions of organic acids or bases are obtained by a process in which
(a) an aqueous solution of a salt of an organic acid or of an organic base and
(b) respectively, an aqueous solution of an inorganic base or of an inorganic acid are each passed into compartments of an exchange cell which are separated from one another by an ion exchange membrane, and the solution (a) and (b) are transported past the surface of the membrane.
