| Abstract |
Di-(2-chloroethyl) sulfide is a vesicant widely reported in international literature and continues to be a serious international threat. Vapor pressures are one of the most important liquid properties that determine or influence the volatility, reactivity, persistency, toxicity, flammability, solubility, and transfer processes of chemicals. Thus, it is necessary to have reliable information available on vapor pressures and the properties derived from vapor pressures for di-(2-chloroethyl) sulfide. Saturation vapor concentrations, boiling points, and enthalpies of vaporization are some of the properties derived from vapor pressures. In response to the need to extrapolate the vapor pressure data for di-(2-chloroethyl) sulfide beyond measured values, it was necessary to review the literature data for consistency. The data found in the literature were selected, combined, fitted, and analyzed to make the best use of the data available. Data from several sources and a variety of methods fit together extremely well to give an excellent fit. The boiling point of di-(2-chloroethyl) sulfide is calculated to be 217.8 +/- 3.1 deg C. The best estimates and 95% confidence expected deviations of the calculated vapor pressures, saturation vapor concentrations, and enthalpies of vaporization are provided over a range of temperatures....
