ABSTRACT:
Solutions of sulfuric acid having a polyamide, such as gelatin, dissolved therein are less corrosive than polyamide-free solutions of sulfuric acid of equal sulfuric acid concentration, while retaining essentially all of the acidity. The polyamide-safened sulfuric acid solutions of the invention are useful in place of sulfuric acid solutions for many purposes, e.g., as cleaners and herbicides, and for the treatment of cellulosic materials.
