Vapor–Liquid Equilibrium Data for the Morpholine-4-carbaldehyde + n-Hexane or n-Heptane Binary Systems Using a Static-Synthetic Apparatus

Abstract

Precise isothermal binary vapor–liquid equilibrium (VLE) measurements were performed for the morpholine-4-carbaldehyde + n-hexane or n-heptane systems at (343.15, 363.15, and 393.15) K using a static-synthetic apparatus. The P–x data measured were processed using both the model-dependent and model-independent approaches. Infinite dilution activity coefficients were estimated by the extrapolation of VLE data by three different methods. Excess enthalpy and entropy data were predicted from VLE data using the Gibbs–Helmholtz relation.
