heal.abstract	An experimental study was conducted in order to investigate the Vapor- Liquid equilibrium of binary mixtures of Ethanol- Butan-2-ol, Methanol - Ethanol, Methanol - Buat-2-ol, Ethanol - Water, Methanol - Water, Acetone - Ethanol and Acetone - Butan-2-ol at ambient pressure using the dynamic apparatus Labodest VLE 602. The experimental apparatus consisted of a constant volume boiling chamber with a heating element controlled by an electrical controller for the adjustment of heating power, an equilibrium chamber ("Cottrell pump"), a pressure sensor for measuring and controlling pressure as well as options for measuring vapor and liquid temperature. All present data are compared to the available experimental data from the literature and show good accordance in terms of Txy and xy plots for both, experimental and calculated data based on regressed Van Laar parameters. For the acetone based systems the experimental results show the highest deviations from literature of all investigated systems, most likely caused by high volatility of acetone. Summarizing, results show taht the apparatus and proposed procedure allow satisfactory determination of vapor liquid equilibrium of binary organic and aqueous systems. The Van Laar activity coefficient model - despite of its simplicity - allows a good reproduction of vapor - liquid equilibrium of the investigated systems based on regressed interaction parameters.	en
