| Abstract: | It has been found that an ordinary reaction calorimeter can be used for the determination of small heat effects (10^-^3 to 10^-^4 C temperature change) by correctly evaluating the Newton's cooling constant K through a reference temperature technique. This technique was applied to the determination of the integral enthalpies of solution of L(+)-aspartic acid and L(+)-glutamic acid in water in the concentration range of 10^-^3 to 10^-^4 mol/kg which were found equal to 25.8+/-0.6 and 25.7+/-0.4kJ/mol respectively (twice standard deviation). No CH2 increment effect has been revealed in the solution enthalpies of these two amino-acids. |
