Bubble temperatures at 95.8 kPa, over the entire composition range are measured for the binary mixtures formed by decane with cyclohexanone, 1,2-dimethoxyethane, tetrahydrofuran and ortho-, meta- and para-xylenes, making use of a Swietoslawski type ebulliometer. The liquid phase composition versus temperature measurements is found to be well represented by the Wilson model. (C) 2004 Elsevier B.V. All rights reserved.
