Abstract:
Thiodiglycol (TDG) is the predominant hydrolysis product of the chemical warfare agent sulfur mustard. The extraction of TDG was investigated using pressurised liquid extraction and the results compared for a variety of different solvents and soils. TDG was analysed underivatised by gas chromatography with flame photometric detection. A mixture of methanol-water (9:1), proved to be the most efficient extracting solvent for TDG at a temperature of 150 degrees C and 10 MPa.
