Reactions of Mustard on Concrete
The reactions of the blister agent mustard, (bis(2- chloroethyl) sulfide, HD), and chloroethyl phenyl sulfide, CEPS*, a simulants, were monitored on concrete. asphalt and sand substrates. The CDC13 extract of concrete monoliths was analyzed using both NMR and GC/MSD; the percent HD extracted depended upon its contact time with the concrete before extraction. Vinyl, hydroxyl, sulfoxide, and dimerized products were detected. 13C SSMAS NMR measurements of CEPS* on the concrete. asphalt and sand substrates indicated a strong interaction between the CEPS* and asphalt and one type of concrete; all of the other interactions were weak. The CEPS* that was placed on the CZ2000 concrete reacted over a period of four weeks to form hydrolysis and dimerized products; no reaction was detected on the sand. TinkerB, or ACE substrates over this period of time.
