Abstract

The pyrolysis of diethyl sulfide, a simulant for mustard chemical warfare agents, was studied in a turbulent flow reactor with analysis by GC/MS and FTIR. Experiments were performed at four different conditions between 630 °C and 740 °C and with maximum residence times between 0.06 and 0.08 s. Samples were taken on the centerline of a turbulent flow reactor. Mixing characteristics in the reactor were determined by using carbon monoxide as a tracer. 80% destruction of diethyl sulfide was observed for the experiment at the temperature of 740 °C, and the residence time of 0.06 second. The following species were quantified: diethyl sulfide, ethylene, methane, acetylene, carbon disulfide, and thiophene. In addition, ethane, ethanethiol, methyl thiirane CH3-(Cy-CH-CH2-S), ethyl methyl disulfide, and diethyl disulfide were identified but not quantified. A light yellow solid containing sulfur condensed in sampling probes. Experimental data was compared to plug flow calculations with a detailed chemistry.
