Experimental and Predicted Vapor–Liquid Equilibrium for Diisopropanolamine with m-Cresol and 2,6-Dimethylphenol at 20.0 kPa

Abstract: Measurements of isobaric vapor−liquid equilibrium (VLE) results for binary systems of m-cresol (MC) + diisopropanolamine (DIPA) and 2,6-dimethylphenol (DMP) + DIPA and the ternary system of MC + DMP + DIPA were conducted at the pressure of 20.0 kPa. The binary VLE experimental data showed that DIPA had stronger interaction with MC than DMP. The ternary system experimental VLE data showed that DIPA could improve the relative volatility of DMP to MC. The binary experimental data were checked by using Herington a… Show more

“…The comparison between the experimental data and the regression results of the models are shown in Figures 5−7 The experimental relative volatilities of camphene + (±)-limonene, camphene + (+)-3-carene, and (±)-limonene + (+)-3-carene system are compared with results calculated 28,53 using model parameters in Table 8, plotted in Figures 8, 9, and 10, which clearly demonstrate that the relative standard uncertainty of the model for the relative volatility of these systems are better than 0.05, 0.02, and 0.02, respectively. This demonstrates that the experimental data are in agreement with calculated results.…”

“…Some vapor–liquid equilibrium (VLE) systems for separation processes of phenolic compounds from pyrolysis oil have been investigated. The binary systems [including MC + o -cresol (OC)/diisopropanolamine (DIPA) and 2, 6-dimethylphenol (2, 6-DMP) + OC/MC/DIPA] and ternary systems (MC + 2, 6-DMP + DIPA) were measured and calculated at 20.0 kPa in Leng et al’s work. , The Wilson and NRTL activity coefficient models were adopted to correlate the VLE data, and the regressed data fitted well with the experimental data. Xia et al studied the VLE experiment and calculation of binary systems (butyl acetate + anisole/guaiacol) at 101.33 kPa .…”
