DETECTION OF TRACE AMOUNTS OF CHEMICAL WARFARE AGENTS AND RELATED COMPOUNDS IN RUBBER, PAINT, AND SOIL SAMPLES BY H-1 AND P-31(H-1) NMR SPECTROSCOPY

摘要

H-1 and P-31{H-1} NMR spectroscopy was used in the identification of chemical warfare agents and related compounds present in trace amounts in rubber, paint, and soil samples, The work was done as part of an international Trial Proficiency Test of laboratory performance, NMR spectroscopy provided identifications of bis(2-chloroethyl) sulfide (mustard), bis(2-chloroethylthio)ethane (sesquimustard), dibenz[b,f][1,4]oxazepine (CR), bis(2-hydroxyethyl) sulfide (thiodiglycol), and cyclohexyl ethylphosphonate, and the presence of cyclohexyl methyl ethylphosphonate, 2-methoxyethyl pinacolyl methylphosphonate, and ethylphosphonic acid was supported, One of the spiking compounds, dithiane 1,4-cyclohexane-1-oxide, was not detected, This report describes sample preparations, experiments, spectral analyses, and the results obtained by NMR spectroscopy.
