Abstract

PURPOSE: To efficiently oxidize Na2S in an alkali soln. to sodium thiosulfate in the recovery system of a kraft pulp process by adding a catalyst compsn. contg. water sol. naphthoquinone sulfonates and cpds. of metals having variable valency to the soln. and then contacting the soln. with an O2-contg. gas.
