Standard enthalpies of formation of sodium alkoxides

Abstract

The standard enthalpies of formation of several crystalline sodium alkoxides, Δ H o f(NaOR, cr), have been determined by reaction-solution calorimetry. A linear correlation has been found between Δ H O f(NaOR, cr) and Δ H o f(ROH, 1/cr) for R = n-alkyl, enabling the prediction of data for other sodium alkoxides. The results were also used to derive the lattice energies and the thermochemical radii of the anions OR −.
