ABSTRACT

The authors declare that data presented in the article entitled Liquid-Liquid Equilibria for Monoethylene Glycol + Water + Alkane Systems in the Range (273 to 313) K and Atmospheric Pressure [ J. Chem. Eng. Data 2004, 49, 1577-1580] are completely erroneous. In the present study, the authors report new solubility data for two of the eight ternary systems mentioned in the previously cited article: monoethylene glycol (MEG) + water + n-hexane/2,2,4-trimethylpentane. The experimental protocol was first validated by studying the liquid-liquid equilibria of four binary mixtures, MEG + n-hexane/2,2,4-trimethylpentane and water + n-hexane/2,2,4-trimethylpentane, under atmospheric pressure at T = 283.15 K, T = 303.15 K, and T = 323.15 K. The experimental results have been compared with the available literature data, and a good agreement has been found.
