Vapor Pressure of 2-Chlorovinyl Dichloroarsine (Lewisite)

Abstract

Previous vapor pressure data for the vesicant chemical warfare (CW) agent 2-chlorovinyl dichloroarsine (Lewisite) was acquired in the 1920s to 1940s, and reported values in the ambient temperature range have varied widely. The generally accepted values for the compound at 20 and 25 deg C were extrapolated from empirical data that were acquired down to only 50 deg C. We have acquired new data in the range of 2 to 24 deg C. By combining these data points with historical data, it has been possible to extend usefulness of the Antoine equation for calculating the vapor pressure of Lewisite from 0 to 193 deg C.
