ABSTRACT
The saturation pressure of R-methylbenzenemethanol at (293 to 363) K was measured by the static method. The total pressure (P, T, x) was measured by the static method for the system R-methylbenzenemethanol + water at (293.15, 303.15, 313.15, 323.15, 333.15, 343.15, 353.15, and 363.15) K. The system is forming two liquid phases. The solubility was determined with the ampule method. The density inversion temperature was observed in the liquid phases. An azeotrope was found in the system. Below 350 K, it is a positive homoazeotrope, while above this temperature it is a positive heteroazeotrope. The experimental vapor pressures were correlated with the Antoine equation, while VLE was correlated with the NRTL equation.
