Abstract
Abstract The energies of combustion of 2-methylpropanamide, 2,2-dimethylpropanamide, and 1-adamantyl carboxamide have been determined using a static bomb calorimeter. The vapour pressures have been measured over a temperature range of about 15 K by the Knudsen-effusion technique. From the experimental results the following quantities for the three compounds, at 298.15 K, have been derived: Compound Δ f H m o (cr) Δ sub H m o Δ f H m o (g) kJ·mol −1 kJ·mol −1 kJ·mol −1 2-Methylpropanamide −368.6 ± 0.9 86.0 ± 0.2 −282.6 ± 0.9 2,2-Dimethylpropanamide −399.7 ± 1.3 86.6 ± 0.4 −313.1 ± 1.4 1-Adamantyl carboxamide −427.0 ± 2.4 108.0 ± 0.5 −319.0 ± 2.5 The structural effects on the thermochemical properties have been studied.
