A small-capacity apparatus for vapor-liquid equilibrium (VLE) measurement was developed. The overall charge of the still with a provision for vapor and liquid recirculations was about 38 cm(3) of the solution. The performance of the proposed apparatus was tested by determining the VLE for the methanol + benzene system at 101.3 kPa. The results obtained were satisfactory. The isobaric VLE were measured for three binary systems, CH3OCH(CF3)(2) (1)+ methanol (2), CH3OCH(CF3)(2) (1)+ ethanol (2) and CH3OCH(CF3)(2) (1)+ 2-propanol (2) at 101.3 kPa using the proposed apparatus. All three binary isobaric systems form a minimum boiling azeotrope. The azeotropic points are x(1)(AZ) = 0.711 mole fraction and T(AZ)= 318.36 K for CH3OCH(CF3)(2) (1) + methanol(2) system, x(1)(AZ)= 0.859 mole fraction and T(AZ) = 322.21 K for CH3OCH(CF3)(2) (1)+ ethanol(2) system, and x(1)(AZ)= 0.918 mole fraction and T(AZ)= 323.44 K for CH3OCH(CF3)(2) (1)+ 2-propanol(2).
