碩士 === 明新科技大學 === 化學工程研究所 === 95 === Liquid-liquid equilibrium (LLE) data for the systems water + 2-propanol + methyl methacrylate, butyl methacrylate or isobutyl methacrylate, water + 2-butanol + methyl methacrylate, butyl methacrylate or isobutyl methacrylate, and water + 2-pentanol + butyl methacrylate and isobutyl methacrylate were determined at atmospheric pressure over temperatures of 288.15 K and 318.15 K. The reliability of the experimental tie-line data was determined through the Othmer-Tobias and Bachman plots. The new LLE data were also compared with the values correlated by the NRTL and UNIQUAC models. Good quantitative agreement was obtained with these models. Overall average deviation values are below 0.0080.
