Abstract

PURPOSE: To neutralyze a soln. of an org. cpd. with caustic alkali without loss of the org. cpd. and to recover the caustic alkali of high purity, by effecting the reaction of one or more kinds of carbonyl cpds. in the presence of caustic alkali to form a soln. of the org. cpd., then by electrodialyzing the soln. in an electrolytic cell equipped with a cation exchange membrane.
CONSTITUTION: One or more kinds of carbonyl cpd. (e.g., HCHO, CH3CHO) is subjected to aldol condensation or Cannizzaro reaction to form a reaction liq., which is electrodialyzed beyond the neutralization point by feeding the liq. to the anodic chamber 1 of an electrolytic cell having a cation exchange membrane 3. Thereby, 5W15 N caustic alkali of high purity is recovered from cathodic chamber 2
