Non-aqueous generation of chlorine dioxide
View Patent ↗Disclosed is a method of making a non-aqueous chlorine dioxide solution by combining a chlorite salt and a non-aqueous carboxylic acid and the non-aqueous chlorine dioxide solution made by this method. Also disclosed are methods of disinfecting an object by applying the non-aqueous chlorine dioxide solution to the object and methods of disinfecting a liquid by adding the non-aqueous chlorine dioxide solution to the liquid.
1. A method of making a non-aqueous chlorine dioxide solution comprising: combining a solid chlorite salt and a liquid non-aqueous carboxylic acid to produce a non-aqueous chlorine dioxide solution.
2. The method of claim 1 , wherein the chlorite salt is sodium chlorite.
3. The method of claim 1 , wherein the non-aqueous carboxylic acid is a fatty acid of the formula RCOOH, wherein R is an aliphatic group.
4. The method of claim 3 , wherein the non-aqueous carboxylic acid is octanoic acid.
5. The method of claim 1 , wherein the concentration of chlorite salt is at least about 0.1 g per liter non-aqueous carboxylic acid.
6. The method of claim 1 , wherein the concentration of chlorite salt is at least about 1 g per liter non-aqueous carboxylic acid.
7. The method of claim 1 , further comprising adding a hydrotrope to at least one of the non-aqueous carboxylic acid and the non-aqueous chlorine dioxide solution to produce a water-compatible non-aqueous chlorine dioxide solution.
8. The method of claim 1 , further comprising adding an antimicrobial to at least one of the non-aqueous carboxylic acid and the non-aqueous chlorine dioxide solution.
9. The method of claim 1 , further comprising adding a wetting agent to at least one of the non-aqueous carboxylic acid and the non-aqueous chlorine dioxide solution.
