Abstract: Isothermal P-x data tor the binary systems methanol-methyl methacrylate and methanol-water, and isothermal P-x’-x" data for the binary system methyl methacrylate-water have been determined at 25, 35, 45, 55 and 60℃. Based on the maximum likelihood principle, the modified UNIQUAC model pa rameters for these binary systems were obtained by fitting the experimental data. Vapor compositions were then calculated, and the results were compared with literature data.
