Volumetric properties of (peg 400 + water) and (peg 400 + ethanol) mixtures at several temperatures and correlation with the jouyban-acree model

Molar volumes and excess molar volumes were investigated from density values for (PEG 400 + water) and (PEG 400 + ethanol) binary mixtures at temperatures from 283.15 K to 313.15 K. Both systems exhibit negative excess volumes probably due to increased interactions like hydrogen bonding and/or large...
