摘要：

Isobaric vapour-liquid equilibria have been experimentally determined for the binary systems methanol + dimethyl carbonate, ethanol + dimethyl carbonate, dimethyl carbonate + 1-propanol, dimethyl carbonate + 1-butanol and dimethyl carbonate + 1-pentanol at 101.3 kPa. The activity coefficients were calculated to be thermodynamically consistent and were correlated with the Wilson and UNIQUAC equations. Interaction parameters related to the carbonate group (-COO-) and alcohols, in ASOG and UNIFAC methods, have been determined using our experimental VLE data. The experimental results, as well as those by other authors, agree with the calculated VLE using the new ASOG and UNIFAC parameters. (C) 2002 Elsevier Science B.V. All rights reserved.
