Reactions of Mustard on Concrete
The reactions of the blister agent mustard, (bis(2-chloroethyl) sulfide, HD) were monitored on concrete substrates. The CDCl3 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, and sulfoxide products were detected. C SSMAS NMR measurements of HD* on the concrete substrates indicated a strong interaction between the HD* and the concrete that has silica filler; the interactions between the HD* and the two concretes that had limestone filler were weak. C SSMAS NMR measurements of HD* on concrete showed that hydrolysis products were present after six days of exposure time.
