✦ Synopsis

Excess molar volumes of 2, 5, 8, 11-tetraoxadodecane q propyl formate or methyl propanoate Ž . at the temperatures 278.15, 288.15, 298.15, and 308.15 K and atmospheric pressure were obtained from density measurements with a vibrating-tube densimeter. Excess molar isobaric Ž . heat capacities of 2, 5, 8, 11-tetraoxadodecane q propyl formate at the temperatures Ž . 288.15, 298.15, and 308.15 K and atmospheric pressure were determined with a differential scanning calorimeter. The results are compared with literature values of binary mixtures containing C H O ester isomers. ᮊ 1997 Academic Press Limited 4 8 2
