| Abstract: | The synthesis of propyl p - hydroxybenzoate from p - hydroxybenzoic acid and propanol is a complex reaction system. The standard heat of formation, standard entropies, heat capacity and vapour heat of each subtance were calculated by methods of Benson - group contribution. The curve of equilibrium constant vs temperature was obtained. It was very important for experimental research and scale up of the process. |
