THERMODYNAMIC PROPERTIES OF ORGANIC DERIVATIVES OF THE LIGHTER ELEMENTS.

Abstract

Thermochemical research was carried out on trimethylamineborane, triethylamineborane, aluminum borohydride, lithium alkyls, hexafluorobenzene, and diamines. Results presented for trimethylamineborane and triethylamineborane include: enthalpies of combustion and formation, molal heat capacities of the condensed phases, phase transformation and melting point temperatures, third law entropies, Gibbs energies and equilibrium constants of formation. A scheme was developed for an improved evaluation of the N-F thermochemical bond energy through experimental determinations of the enthalpies of combustion of the related diamines. The status of work on aluminum borohydride and the lithium alkyls was reviewed. Experimental measurements on the enthalpies of vaporization and vapor heat capacity of hexafluorobenzene were completed. (Author)
