Thermophysical Properties and Spectral Characterization of EA 6043
Abstract
Selected physical and spectroscopic properties of O-(n-butyl)-S-(2-diethylaminoethyl) methylphosphonothiolate, identified in this report as EA 6043, were determined and are reported herein. The title compound is a structural isomer of VX [O-ethyl-S-(2-diisopropylaminoethyl) methylphosphonothiolate] and Russian VX [O-isobutyl-S-(2-diethylaminoethyl) methylphosphonothiolate]; and as such, it is also an extremely potent acetylcholinesterase inhibitor. Density, viscosity, surface tension, and vapor pressure for EA 6043 were measured. These properties were correlated to temperature to provide the basis for interpolation and extrapolation of the measured data. Temperature-dependent volatility and heat of vaporization and entropy of vaporization were calculated for EA 6043 on the basis of correlations to the vapor pressure data. Comparisons of selected properties of the structural isomers are provided when possible. Electron impact mass; 1H, 13C, and 31P nuclear magnetic resonance; Fourier transform infrared; and Raman spectra are reported for EA 6043.
