Abstract
A universal decontamination formulation is disclosed based on the in situ generation dioxirane(s) under non-corrosive neutral conditions for the neutralization of chemical and biological warfare (CBW) agents. The composition relates to the generation of dioxiranes by mixing a monopersulfate-containing compound in the presence of a ketone in water buffered with a carbonate-type buffer, producing a pH neutral formulation that provides effective reactivity towards CBW agents over a wide range of temperatures.
Claims21
A composition consisting of:
- water;
- one or more monopersulfate compounds;
- one or more buffers selected from the group consisting of alkali metal salts of bicarbonate and carbonate;
- one or more co-solvents, wherein at least one of the co-solvents is selected from the group consisting of acetonitrile, tert-butanol, propylene carbonate, propylene glycol, and polypropylene glycol;
- and
- one or more ketones, at least one of said ketones being selected from the group consisting of acetone, 2-butanone, 2-pentanone, 2-hydroxy-4-methyl-2-pentanone, hexafluoroacetone, trifluoroacetone, acetophenone, camphorsulfonic acid, and levulinic acid,
- wherein the composition has a pH of from 5 to about 9 and is formulated to achieve in situ generation of dioxirane.
A composition consisting of:
