Abstract
A process for the decontamination of chemical warfare agents. More particularly, a process for the decontamination of the vesicant HD by oxidation to its corresponding sulfoxide and nerve agents VX and GD by perhydrolysis to their non-toxic phosphonic acids using environmentally safe reactants, specifically a peroxomolybdate compound having a dominant tetraperoxomolybdate species and peroxy anion.
Claims27
A process for decontaminating a chemical warfare agent comprising:
- contacting at least one compound having a formula selected from the group consisting of ROP(O)(CH3)F, wherein R is either 2-propyl, pinacolyl, or cyclohexyl;
- R″OP(O)(CH3)SR′, wherein R″ is ethyl and R′ is 2-(diisopropylamino)ethyl;
- and bis(2-chloroethyl)sulfide, with a peroxomolybdate compound having the formula Mo(O)x(O—O)(4−x)2−, wherein x=0-3.
A process for decontaminating a chemical warfare agent comprising:
- a) forming a peroxomolybdate compound having the formula Mo(O)x(O—O)(4−x)2−, wherein
- x=0-3 by reacting a peroxide component and a molybdate component;
- and
- b) contacting said peroxomolybdate compound with at last one chemical warfare agent having a formula selected from the group consisting of:
- ROP(O)(CH3)F, wherein R is either 2-propyl, pinacolyl, or cyclohexyl;
- R″OP(O)(CH3)SR′, wherein R″ is ethyl and R′ is 2-(diisopropylamino)ethyl;
- and bis(2-chloroethyl)sulfide.
