Recent work from our laboratory focused on the physical properties of chemical warfare agents and their surrogates, precursors, and degradation products. This report documents vapor pressure data for four sulfur-containing decomposition products from bis-2-chloroethyl sulfide HD. These data were measured using an ASTM International method that is based on differential scanning calorimetry DSC. The data presented herein were used to determine temperature vapor pressure correlations. The fit constants were used to determine temperature-dependent thermodynamic properties and to enable interpolation and limited extrapolation of the data. The new data are compared to previous literature. In most cases, the agreement is good. In all cases, the DSC data expand the range of previously reported measurements.
