摘要：

Measurements of density for glycerol-water solutions have been carried out along a co-existing curve by using the pycnometer method in the range of temperatures from 293 to 363 K and in the range of concentration from 0.225 to 0.552 mol fraction of glycerol. It's shown that the concentration curve of density is not monotone. The density of the glycerol-water solution is a jump function of concentration. The peak of this curve is observed at concentration of 0.33 mol fraction of glycerol. It is found that this concentration is characterized by the highest values of isobaric expansion. We also found that the investigated glycerol-water solutions are obtained with compression based on configurational rather than energetic principles. (C) 2006 Published by Elsevier B.V.
