Vapor–Liquid Equilibrium of γ-Valerolactone and Formic Acid at p = 51 kPa

摘要: Because of its outstanding physical and chemical properties, γ-valerolactone (GVL) has been identified as a promising renewable platform molecule for the industry. Its synthesis can be performed via many catalytic routes; however, each method results in formation different product mixture, which components have to separated before subsequent utilization GVL. The use formic acid (FA) hydrogen source producing GVL by homogeneous-transfer hydrogenation could one most suitable ways, whereas mixture contain FA, GVL, water. In present study, isobaric vapor–liquid equilibrium data FA was determined. experimental were correlated with Wilson, NRTL, UNIQUAC models compared ideal vapor pressures well modified UNIFAC activity coefficient models. refractive indexes also determined over whole concentration range at T = 293.2 298.2 K.
