Abstract

A detoxicant solution includes 0.1 to 50 parts by weight of at least one Friedel-Crafts reagent (Lewis acids) (I); 0.5 to 80 parts by weight of one or more of the following specific solvents (II): dimethyl sulfoxide, 1,3-dimethyl-2-imidazolidinone or octamethylcyclotetrasiloxane; and 1 to 80 parts by weight of an alcoholic solvent (III). The term “parts by weight” relates in each case to 100 parts by weight of the complete detoxicant solution.

Claims

1. A detoxicant solution, comprising:

0.1 to 50 parts by weight of at least one Friedel-Crafts reagent selected from the group consisting of boron trifluoride, boron trichloride, aluminium trichloride, iron trichloride, iron tribromide and titanium tetrachloride;

0.5 to 80 parts by weight of one or more specific solvents selected from the group consisting of dimethyl sulfoxide, 1,3-dimethyl-2-imidazolidinone, and octamethylcyclotetrasiloxane;

0.25 to 25 parts by weight, based on 100 parts by weight of the detoxicant solution, a saturated alicyclic hydrocarbon having 10 to 16 carbon atoms;

1 to 80 parts by weight of an alcoholic solvent; and

wherein the term “

parts by weight”

relates in each case to 100 parts by weight of the detoxicant solution in total.

2. The detoxicant solution according to claim 1, which further comprises 0.1 to 5 parts by weight, based on 100 parts by weight of the detoxicant solution, of 1H-benzotriazole.

3. The detoxicant solution according to claim 1, wherein a content of the Friedel-Crafts reagent(s) in the complete detoxicant solution amounts to from 1 to 40 parts by weight.

4. The detoxicant solution according to claim 1, wherein a content of the specific solvent(s) in the complete detoxicant solution amounts to from 5 to 75 parts by weight.

5. The detoxicant solution according to claim 1, wherein a content of the alcoholic solvent(s) (III) in the complete detoxicant solution amounts to from 5 to 75 percent by weight.

6. The detoxicant solution according to claim 2, wherein a content of the 1H-benzotriazole in the complete detoxicant solution amounts to from 0.5 to 2 parts by weight.

7. The detoxicant solution according to claim 1, wherein a content of the saturated alicyclic hydrocarbon in the complete detoxicant solution amounts to from 1 to 20 parts by weight.

8. The detoxicant solution according to claim 1, wherein the saturated alicyclic hydrocarbon is cyclododecane.

9. A method for detoxifying a surface contaminated with a chemical and/or biological warfare agent, which comprises spraying the detoxicant solution according to claim 1 onto the contaminated surface.

10. A method of preparing a detoxicant solution, which comprises:

mixing;

0.1 to 50 parts by weight of at least one Friedel-Crafts reagent selected from the group consisting of boron trifluoride, boron trichloride, aluminium trichloride, iron trichloride, iron tribromide and titanium tetrachloride;

0.5 to 80 parts by weight of one or more specific solvents selected from the group consisting of dimethyl sulfoxide, 1,3-dimethyl-2-imidazolidinone, and octamethylcyclotetrasiloxane;

0.25 to 25 parts by weight, based on 100 parts by weight of the detoxicant solution, a saturated alicyclic hydrocarbon having 10 to 16 carbon atoms; and

1 to 80 parts by weight of an alcoholic solvent;

at a temperature between 10°

C. and 50°

C.;

wherein the term “

parts by weight”

relates in each case to 100 parts by weight of the detoxicant solution in total.

11. The method according to claim 10, which further comprises admixing 0.1 to 5 parts by weight, based on 100 parts by weight of the detoxicant solution, of 1H-benzotriazole.
