Thermodynamic Properties of Organic Derivatives of the Lighter Elements and Thermodynamic Properties of Fluids

摘要

An investigation of strained small ring systems as possible group constituents in synthetic high energy fuels was continued. The purification of research samples of 1,2-epoxybutane, trans-2,3-epoxybutane, and cyclopentylamine is described. Thermodynamic properties for 1,2-epoxybutane in the liquid state are reported. Conversion to the gaseous state awaits vapor pressure measurements which are in progress. Vapor pressure and enthalpy-of-vaporization measurements were completed for trans-2,3-epoxybutane. Combustion and low-temperature thermal measurements are in progress; however, these data indicate that the sample purity may not be adequate for some of the properties. (Author)
