Desenvolvimento de um programa para o cálculo da variação da entalpia de uma série de compostos orgânicos

Abstract

The calculation of enthalpy variation is fundamental in solving various problems, because it is linked to the energy balance, very present in the study of Chemical Engineering, and important for the understanding of the transformations that occur in each system. The insertion of tools within engineering, such as programs for calculating different properties, which present reliable data and an easy-to-understand interface, is of extreme importance to quickly obtain the desired results. Therefore, this work aims to develop an algorithm to calculate the specific heat at constant pressure and then the enthalpy variation of organic compounds within the MATLAB® environment. The data necessary to perform the calculation is found in a database that interacts with the program. The methodology used is classified as action research, because a practical application is developed from a specific problem.
