Abstract

Aromatic N-halosulfonamide organic compounds have been known for over one hundred years. The ability of these compounds to release active halogen ions has been utilized in a range of biocidal and fungicidal applications. The most widely used halogen sulfonamide organic compound for these applications is Chloramine-T. This invention deals with the new use of discovered compositions of matter, halo active aromatic sulfonamide organic compounds and use of solutions of these compounds as, odor control agents. The odor control solutions may be buffered to a predetermined pH. The odor control compositions may further incorporate small percentages of low molecular weight alcohols and wetting agents.

Claims (27)

1. A process for controlling odor being emitted by an odor causing material which comprises treating the material with a solution containing an effective amount of a halo active aromatic sulfonamide compound having the formula:

wherein X is a halogen; R 1 is chlorine; and M is an alkali or alkaline earth metal.

2. The process of claim 1 , wherein the concentration of the sulfonamide compound is from about 0.5 to about 10 weight percent.

3. The process of claim 1 , wherein the solution further incorporates an effective amount of a wetting agent which essentially does not react with the sulfonamide compound.

4. The process of claim 3 , wherein the wetting agent is an anionic or nonionic wetting agent.

5. The process of claim 1 , wherein the solution is buffered to a pH of from about 7 to about 10.

6. The process of claim 1 wherein the solution is buffered to a pH of from about 8 to about 9.5.

7. The process of claim 1 , wherein the pH of the solution is buffered to a pH of greater than 10.

8. The process of claim 1 , wherein the solution further incorporates an effective amount of a low molecular weight alcohol.

9. A process for controlling odor being emitted by an odor causing material which comprises treating the material with a solution containing an effective amount of a halo active aromatic sulfonamide compound having the formula:

wherein X is a halogen; R 3 is methoxy or nitro; and M is an alkali or alkaline earth metal.

10. The process of claim 9 , wherein the concentration of the sulfonamide compound is from about 0.5 to about 10 weight percent.

11. The process of claim 9 , wherein the solution further incorporates an effective amount of a wetting agent which essentially does not react with the sulfonamide compound.

12. The process of claim 11 , wherein the wetting agent is an anionic or non ionic wetting agent.

13. The process of claim 9 , wherein the solution is buffered to a pH of from about 7 to about 10.

14. The process of claim 9 , wherein the solution is buffered to a pH of from about 8 to about 9.5.

15. The process of claim 9 , wherein the pH of the solution is buffered to a pH of greater than 10.

16. The process of claim 9 , wherein the solution further incorporates an effective amount of a low molecular weight alcohol.

17. A process for controlling odor being emitted by an odor causing material which comprises treating the material with a solution containing an effective amount of a halo active aromatic sulfonamide compound having the formula:

wherein X is a halogen; and M is an alkali or alkaline earth metal.

18. The process of claim 17 , wherein the concentration of the sulfonamide compound is from about 0.5 to about 10 weight percent.

19. The process of claim 17 , wherein the solution further incorporates an effective amount of a wetting agent which essentially does not react with the sulfonamide compound.

20. The process of claim 19 wherein the wetting agent is an anionic or nonionic wetting agent.

21. The process of claim 17 , wherein the solution is buffered to a pH of from about 7 to about 10.

22. The process of claim 17 , wherein the solution is buffered to a pH of from about 8 to about 9.5.

23. The process of claim 17 , wherein the pH of the solution is buffered to a pH of greater than 10.

24. The process of claim 17 , wherein the solution further incorporates an effective amount of a low molecular weight alcohol.
