ABSTRACT

A static total pressure apparatus was used to measure isothermal VLE for systems containing propanenitrile + n-butane (322.02 K), + 1-butene (312.55 K), + 2-methylpropane (307.85 K) and +2-methylpropene (312.59 K). Vapour liquid equilibrium (VLE) for propanenitrile + tert-butyl ethyl ether (ETBE) was measured both with the static total pressure apparatus at 313.15 K and 358.5 K and with a glass circulation still apparatus at 102.6 kPa and 65.2 kPa. The system of propanenitrile + ETBE evidenced azeotropic behaviour.
