摘要：

Density and speed of sound data for dilute aqueous solutions of four linear 2-alkoxyethanols, H-(CH2)(n)-O-CH2-CH2-OH, CnE1 for n = 1, 2, 3, 4, were measured using the Anton Paar DSA 5000 vibrating-tube densimeter and sound analyzer in the temperature range from 278.15 to 343.15 K and at atmospheric pressure. Standard molar volumes and standard molar isentropic compressions were evaluated from the measured data. Present data were compared with values available for selected linear aliphatic polyethers and poly(ethylene glycols) and structure property relationships were analyzed. Apparent molar quantities of aqueous 2-butoxyethanol in wider concentration range were evaluated and effects of aggregation of the solute molecules were considered.
