Abstract
The partial vapour pressures and thus the activity coefficients of GB and GD and water in aqueous solutions of the agents have been measured through the range of mole fractions in which the agent and water are miscible. The technique used was to measure the total vapour pressure over the agent/water mixture and then to solve numerically for the partial vapour pressures with a computer implementation of the Gibbs-Duhem equation. The agent activity coefficients display the hydrophobic nature of the nerve agents at mole fractions less than one half, but are close to unity otherwise.
