ABSTRACT
Thiodiglycol (TDG), also known as bis(2-hydroxyethyl) sulfide and thiodiethanol, is a precursor of the blister agent sulfur mustard (bis(2-chloroethyl) sulfide). It is also a hydrolytic degradation product, and as such, it is of considerable forensic interest to the chemical defense community. Experimental vapor pressure data have been reported previously for TDG at T = (283.15 to 353.15) K, in addition to reduced-pressure boiling points at T = (353.15 to 454.65) K. New data have been measured using two complementary American Society for Testing and Materials International methods at T = (417.75 to 538.58) K by differential scanning calorimetry and in the ambient temperature range using saturator methodology at T = (298.15 to 313.15) K. The new TDG vapor pressure data are in sharp contrast to widely accepted values from previous literature.
