Abstract

PURPOSE:To substantially reduce the cost for purifying an aq. NaCl soln. by concentrating an aq. caustic soda soln. obtd. from a cell provided with an asbestos diaphragm after which the precipitated NaCl is used for an aq. NaCl soln. to carry out electrolysis using a cation exchange membrane.
