摘要：
Excess molar enthalpies h(E) of different glycol+methanol and glycol+ethanol mixtures at atmospheric pressure were measured at the temperatures (285.65, 298.15, 308.15, and 323.15 K). Glycol+ethanol mixtures were also measured at the temperature 338.15 K. The glycols were the following: ethanediol, 1,2-propanediol, and 1,2-butanediol. The experimental results are correlated using the Redlich-Kister equation and are qualitatively discussed. (C) 1999 Elsevier Science B.V. All rights reserved.
