Abstract

Abstract Standard energies of combustion of ricinoleic acid and methyl ricinoleate were measured experimentally by using a semi-micro bomb calorimeter. The energies of combustion of ricinoleic acid and methyl ricinoleate were used to derive the corresponding standard molar enthalpies of formation ( - Δ f H m ∘ ) in liquid phase at T = 298.15 K. The values of - Δ f H m ∘ for these compounds are (−1097.7 ± 11.6) kJ · mol−1 and (−1027.1 ± 12.4) kJ · mol−1, respectively.
