The Melting Point of Mustard Gas

Abstract

Each tube contained 7 g. of pure sulfur mixed separately with 0.3 g. and 1.0 g. of CoF*; 0.3 g. and 1.0 g. of HgF; 0.5 g. and 1.0 g. of AgF. At the end of the experiments, all tubes were under fairly high pressure indicating formation of the gases had taken place. Only after prolonged heating (about forty-eight hours at 180-440°) was a slight reduction of the viscosity noted.These experiments lead to the opinion that the observed failure of the sulfur fluorides to greatly affect the viscosity of sulfur is just one more instance of the abnormal behavior of fluorine and its compounds when viewed in comparison with the other halogens.

Vapor Pressure of Solid Bis(2-chloroethyl) Sulfide

“…8,9 To the best of our knowledge, accurate experimental data for the vapor pressure of solid HD have not been reported in the literature. It is not suitable to extrapolate liquid-phase HD vapor pressure data below its melting point, 14.45°C, 10 as shown in this report.…”

“…The literature data reported for liquid HD are internally consistent and have been described by an Antoine equation correlation by Penski. , To the best of our knowledge, accurate experimental data for the vapor pressure of solid HD have not been reported in the literature. It is not suitable to extrapolate liquid-phase HD vapor pressure data below its melting point, 14.45 °C, as shown in this report.…”

Parameters for Evaluation of the Fate, Transport, and Environmental Impacts of Chemical Agents in Marine Environments

“…Five independent studies report that 1,1′-thiobis[2-chloroethane] boils at atmospheric pressure with decomposition; ,,− the mean boiling point is 216.9 ± 0.2 °C. Four studies of the melting point of pure 1,1′-thiobis[2-chloroethane] − give a mean melting point value of 14.46 ± 0.04 °C. Several other studies report lower values, presumably because they used less pure material; ,,− lower and broader melting ranges typically apply to weapons-grade material.…”
