Abstract: Gamma-valerolactone (GVL) is used in green technology to produce chemicals and biofuels. Separation of GVL from mixtures within a process is a recurring challenge in chemical plants. Experimental boiling point determination containing its mixtures is fundamental as a preliminary stage of vapor-liquid equilibrium studies. The boiling point of binary mixtures of GVL/water and GVL/ethanol were measured at five compositions each, and range pressure from about 7.0 ?????? to 91.0 ?????? (±0.8??????). Experiments were carried out to determine the boiling point using a simplified ebulliometer. The experimental data were correlated with the Non-Random Two Liquid (NRTL) model. The correlated parameters of the NRTL model were used to calculate the vapor-liquid equilibrium of the mixture using the methodology of Gibbs energy minimization with ideal vapor phase
