2-Chloroethyl ethyl sulfide mustard simulant

Reaction of the sandwich-type POM [(Fc(0H2)2)j(A-a-PW9034)2 9 with a colloidal suspension of silica/alumina nanopartides ((Si/A102)Cl) resulted in the production of a novel supported POM catalyst [146-148]. In this case, about 58 POM molecules per cationic silica/alumina nanoparticle were electrostatically stabilized on the surface. The aerobic oxidation of 2-chloroethyl ethyl sulfide (mustard simulant) to the corresponding harmless sulfoxide proceeded efficiently in the presence of the heterogeneous catalyst and the catalytic activity of the heterogeneous catalyst was much higher than that of the parent POM. In addition, this catalytic activity was much enhanced when binary cupric triflate and nitrate [Cu(OTf)2/Cu(N03)2 = 1.5] were also present [148],... 

The decontamination efficacy of radioprotective agent aminoethylisothiourea and cystamine on rat skin against SM was comparable to standard decontaminants, such as alco-holate, clay, and Fuller s earth (Knezevic and Tadic, 1996). A mixture containing bovine hemoglobin, gelatin, and poi (a Hawaiian foodstuff) on the hydrolytic kinetics of the mustard simulants, 2-chloroethyl ethyl sulfide, 2-chloro-ethyl methyl sulfide and 2-bromoethyl phenyl sulfide, is reported. The kinetic mechanisms and rate constants were dependent upon the mixtures concentration and viscosity (Cemy and Cemy, 1997). 

The third panel of Figure 2 shows the rotational spectrum of 2-chloroethyl ethyl sulfide (2CEES) a mustard gas simulant. The rotational constants and inertial projection of the permanent dipole moment have been previously reported and are reproduced in Table 1. The rotational spectrum of 2CEES is highly congested by the addition of the chlorine atom. The 2CEES spectrum is fragmented by the appearance of two nuclear...

The system was designed to validate the capability of the SILVER IF process to destroy chemical agents VX, GB (both are nerve agents), and HD (distilled mustard). It was also intended to demonstrate the effective destruction of agent simulants chloroethyl ethyl sulfide (CEES) and dimethyl methylphosphonate (DMMP) for comparison with results from the 12 kW system. 

Decontamination of chemical warfare agents (CWA s) is important not only for battlefield applications, but for cleanup as well. Some common CWA s are VX-((9-ethyl S -(2iisopropylamino)ethyl methylphosphonotioate), which is a nerve gas, and HD (mustard gas), which is a blistering agent. For much of the CWA decontamination research, CWA simulants which have similar chemical structures and properties as CWA s but are much less toxic, are used. In the work described here, DMMP (dimethylmethylphosphonate) and 2-CEES (2 chloroethyl sulfide) will be used as CWA simulants for VX and HD,...
