PURPOSE: To provide a cost effective method for liberating org. sulfonic acid which decreases or completely avoids the slats of waste. n CONSTITUTION: An aq. org. sulfonic acid soln. is electrodialyzed by using an electrodialysis cell consisting of the diluting liquid chamber DC, acid chamber AC and base chamber BD indicated by sequence I: (MB/AC/MA/DC/MK/BC) n I (in this case, MB is a bipolar ion exchange member, MA is an anion exchange membrane, MK is a cation exchange membrane and (n) is a figure from 1 to 500), by which the org. sulfonic acid is liberated from the aq. soln. consisting of one of the salts of the aq. org, sulfonic acid soln. n COPYRIGHT: (C)1992,JPO |
