Abstract
The internal energy of combustion of D-asparagine monohydrate is determined by bomb calorimetry, and its standard enthalpies of combustion and formation in the crystal state are calculated. The enthalpies of dissolution of this compound in water and aqueous solutions of potassium hydroxide are measured by standard calorimetric methods. The standard enthalpies of formation of the amino acid and of the products produced as a result of its protonation and dissociation in an aqueous solution are evaluated.
