ABSTRACT:
The diaphragm of a chlor-alkali cell has its useful life prolonged by the unplugging thereof. Unplugging is achieved by shifting the pH gradient in the diaphragm toward the catholyte side. Simultaneously with the shifting of the pH gradient, chelates are formed in the anolyte solution from .alpha.-hydroxyketones and .alpha.-hydroxyaldehydes.
