Vapor Pressure of Russian VX

Abstract

O-isobutyl-S-(diethylaminoethyl) methyl phosphonothiolate (RVX) is a highly toxic compound and a structural isomer of the nerve agent, O-ethyl-S-(diisopropylaminoethyl) methyl phosphonothiolate (VX). The vapor pressure of RVX has been measured using a modified ASTM saturation method between -10 and 18 degrees C and a second ASTM method employing differential thermal analysis between 145 and 232 degrees C. Those data and an Antoine fit to the data are presented and compared to an earlier correlation based on data measured over a narrower temperature range.
