Abstract
The present work reports the values of the gaseous standard (p∘ = 0.1 MPa) molar enthalpies of formation of salicylaldehyde (2-hydroxybenzaldehyde) and salicylamide (2-hydroxybenzamide), at T = 298.15 K. For both molecules, those values were derived from measurements of the standard molar energy of combustion of the condensed compounds, using a static bomb calorimeter, together with measurements of the standard molar enthalpy of vaporization or sublimation, measured by Calvet microcalorimetry.
