Abstract

PURPOSE: To obtain industrial grade conc. sulfuric acid which does not produce white suspended solids even if allowed to stand over a long period, by adding fuming sulfuric acid and/or anhydrous sulfuric acid to industrial grade conc. sulfuric acid in advance so as to regulate the concn. of sulfuric acid to more than 99 wt.%, followed by filtration.
