Resumo

Bio-based products and processes were favored recently, because shifting towards a more sustainable economy might be a long-term solution for global challenges. Within this context, gamma-valerolactone emerges as a sustainable alternative for industrially relevant solvents and as a potential additive for liquid fuels. Yet, few data have been published regarding the solubility behavior of binary mixtures containing this molecule, which is crucial for assessing its possible applications. Hence, this work determined the mutual solubility of gamma-valerolactone and n-tetradecane, a representative molecule of diesel, using the cloud point method at temperatures between 288.15 K and 333.15 K, which guarantees compounds stability. This method was also employed to determine the lactone solubility in commercial diesel at selected temperatures. Results were correlated by the NRTL and UNIQUAC models, which succeeded in representing experimental data but could not predict the upper critical solution temperature. (C) 2018 Elsevier B.V.
