REACTION OF GASEOUS SULFUR MUSTARD WITH ZEOLITE 13X

The behaviour of zeolite 13X, both dried and impregnated with H2O and various amines, when treated with gaseous sulfur mustard, (CICH2CH2)(2)S, has been studied. The capacity to absorb/react with S-mustard was largest for the dried zeolite 13X (1.24-1.41 mmol S-mustard g(-1)). with the capacity of the other samples appearing to depend upon the flee;space within the zeolite rather than upon the type or loading of the potential decontaminant. The product formed from S-mustard within dried zeolite 13X has been investigated by H-1 and C-13 NMR spectroscopy and tentatively assigned the structure HOCH2CH2SCH2CH2S+ (CH2CH2OH)(2).
