Physicochemical Properties for the Reaction Systems: Levulinic Acid, Its Esters, and γ-Valerolactone
Résumé
The use of biomass, particularly second generation one, as renewable raw material is crucial to sustain chemical industry. To favor the development of such processes, one needs to make a cost evaluation, which requires knowledge of processes thermodynamics and kinetics. In this paper, different physicochemical property measurements (viscosity, density, refractive index and specific heat capacity) were done for the systems: hydrogenation of levulinic acid or its esters to γ-valerolactone. From these physicochemical measurements, it was possible to extract the ones of the intermediates and perform a thermodynamic model assessment by using Aspen plus. It was found that Hysys Redlich-Kwong-Soave cubic equation of state and Benedict-Webb-Rubin-Starling virial equation state are suitable to describe these chemical systems.
