ABSTRACT
The isothermal (T ) 323.15 K) and the isobaric (P ) 66.66 kPa and 79.99 kPa) vapor-liquid equilibria (VLE) for the ternary system of 2,2-dimethoxypropane + acetone + methanol were measured with an inclined ebulliometer. The measured results for the ternary system are compared with the calculated ones from the UNIQUAC equation using only temperature-dependent binary parameters obtained from the binary literature values and resulted in satisfactory results. The ternary VLE data are useful in the design of efficient separation process of 2,2-dimethoxypropane, acetone, and methanol.
