Abstract

Laminar flow reactor data are reported on the destruction of diethyl sulfide, a simulant for mustard chemical warfare agents. Liquid diethyl sulfide was metered with a syringe pump into a nitrogen flow, producing an initial loading of 500 ppm. The diethyl sulfide/ nitrogen mixture flowed into an electrically heated quartz flow reactor with ID of 8 mm and length of 2 meters. Runs were performed with maximum temperatures between 542 and 1056 K. With a constant mass flowrate into the system, residence times based on plug flow at the maximum temperatures varied between 1.7 and 3.3 s, and Reynolds numbers varied between 70 and 107. Samples were extracted at the exit of the flow reactor and analyzed with a GC/MS system equipped with a gas sampling valve and J&W GasPro column. 50% destruction of diethyl sulfide was observed for a run with a maximum temperature of 893K, and residence time of 2 s. The following species were observed at the exit of the flow reactor: H2S, CS2, thiophene, ethanethiol, and elemental sulfur. The GC/MS operating conditions did not permit observation of ethylene, an expected decomposition product. Experimental data are compared to plug flow calculations with a preliminary chemical kinetic model.
