Abstract
The parameters of exchange enthalpy, X-12, and entropy, Q(12) have bee n determined for cyclopentane, tetrahydrofurane and 1,4-dioxane with p oly(dimethyl siloxane) around room temperature using inverse gas chrom atography technique. The parameters X-12 Were compared to the paramete rs calculated by means of the Berthelot relationship from characterist ic pressures of the pure components in the mixtures. The parameters Q( 12) were compared to differences of thermal pressure coefficients of t he pure components in the mixtures. (C) 1997 Elsevier Science Ltd. All rights reserved.
