Abstract
An apparatus for vapour - liquid equilibrium measurement at elevated p ressures was built. Construction was based on the Rogalski - Malanowsk i glass ebulliometer designed for precise measurements up to normal pr essure. Experimental procedure was also developed. For the performance test of the proposed apparatus the vapour pressure was measured for f our pure substances (benzene, heptane, cyclohexane and water) and the vapour - liquid equilibrium (VLE) was determined for two binary mixtur es (benzene + heptane and benzene + cyclohexane). The results obtained were satisfactory.
