US Classification:

588200

Abstract:

A process for the detoxification or decontamination of aminoalkyl phosphonothiolates and more particularly, the chemical warfare agent VX and its analogs. The process comprises adding water to the chemical agent so that an hydrolysis reaction of the chemical agent with water occurs at specified molar ratios. In a preferred embodiment, the detoxification process is carried out in situ within the chemical agent storage containers in the field and includes mixing the contents of the container after adding the water. The mixing may be accomplished by shaking, rolling, tumbling or pumping.
