A redetermination of heats of formation of some compounds of biological interest : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Chemistry at Massey University

Abstract

The energies of combustion of thoroughly dried samples of l-histidine, uracil and cytosine were measured at 298.15 K by oxygen-bomb combustion calorimetry. The enthalpies of formation for these compounds were redetermined. It appears that a ten-fold improvement in the accuracy of the results was obtained.
