Vapour-liquid equilibrium for the 1-butene plus methanol, plus ethanol, plus 2-propanol, plus 2-butanol and plus 2-methyl-2-propanol systems at 326 K
A total pressure measurement approach leading to pTz data, that is treated using the method of Barker (1953) to provide pTxy data, has been used to determine isothermal vapour-liquid equilibria for five binary systems 1-butene + methanol, + ethanol, + 2-propanol, + 2-butanol and + 2-methyl-2-propanol at 326 K. Error analysis of the measured results has been presented. All systems exhibited positive deviation from Raoult's law and 1-butene + methanol showed azeotropic behaviour.
