The purpose of this study was to obtain greater accuracy in the measurement of the heat of reaction by combining data from various thermal analysis techniques. Conventional equations that calculate heat of reaction are limited because they do not take in to account mass change. Therefore, an enhanced equation was developed to integrate mass (weight) change to provide greater accuracy. The path chosen to implement this new equation employed simultaneous Thermogravimetric / Differential Thermal Analysis (TG/DTA) that could provide both ΔT and weight data simultaneously. Computer programs were written in C and Pascal languages to provide communication capabilities between computers and to calculate heat of reaction using various equations. This included a qualitative to quantitative (ΔT to ΔH) conversion which was performed to the DTA data file to which the enhanced equation was applied. Various samples were used to test and monitor the performance of the developed equations.
