Isobaric Vapor–Liquid–Liquid Equilibrium for Water + Cyclohexane + Acrylic Acid at 200 mmHg
Isobaric vapor–liquid–liquid equilibrium (VLLE) data were measured for the ternary system water + cyclohexane + acrylic acid at 200 mmHg (absolute pressure). The apparatus are a modified dynamic recirculating still equipped with mixing section for experimental test and a gas chromatography (Agilent GC7890A) for analyzing, respectively. The VLLE data have been used to verify the dependability of the NRTL, NRTL-HOC, and UNIQUAC-HOC models prediction results for the water + cyclohexane + acrylic acid system. The parameters for these models were obtained using experimental data regression. Comparing the predictions and experimental data, the HOC equations have a good effect in vapor phase prediction with a strong self-polymerization of compounds system, and the NRTL-HOC model has a more acceptable prediction of the VLLE data than the UNIQUAC-HOC model.
