Abstract
The hydrolysis reactions of two organophosphorus esters (models for the agents GB, GD, and VX) has been shown to be dramatically increased by the addition of small concentrations (less than or equal to 7 mM) of a copper (II) complex, ((2,2'-dipyridylamine)CU(OH2)2)2)++. These reactions have also been shown to be catalytic in the complex. This system has shown all the requirements needed for effective decontamination of teh organophosphorus based agents. The hydrolysis reaction of 2-chloroethyl ethylsulfide (a model for the agent sulfur mustard or HD) has been shown to be accelerated by up to 25% by the addition of small concentrations (less than or equal to 1 mM) of a copper (II) complex, ((2,2'-dipyridylamine)Cu(OH2)2)++ in 80% v/v ethanol:water, this demonstrates binding of the model compound to the complex, however, in 50% v/v ethanol:water no rate acceleration was observed.
