Abstract:
A process for producing amino acid hydrochloride and an alkali in a three compartment electrodialysis cell containing bipolar, cation and anion membranes, said membranes being arranged to form acid, base, and salt compartments, the process comprising the steps of:a. supplying a stream of salt solution to a salt compartment of an electrodialysis cell, a stream comprising water to a base compartment of said cell, and a liquid comprising an amino acid to an acid compartment of said cell;b. applying a direct current driving force across said cell to produce a conversion of salt to an alkali solution in the base compartments and the amino acid to hydrochloride in the acid compartment; andc. withdrawing the acid and alkali solutions produced step b along with depleted salt solutions, the withdrawal being taken from the respective compartments.
