The isothermal and isobaric (vapour + liquid) equilibria for (2-ethoxypropene + acetone) and (2-ethoxypropene + butanone) measured with an inclined ebulliometer are presented. The experimental results are analyzed using the UNIQUAC equation with the temperature-dependent binary parameters with satisfactory results. Experimental vapour pressures of 2-ethoxypropene are also included. (C) 2005 Elsevier Ltd. All rights reserved.
