Abstract Density and ultrasound measurements have been carried out for aqueous solutions of primary and secondary alcohols and α,ω-diols at 5, 10, 20, and 40°C. The density data have been used to calculate partial molal volumes and expansibilities at infinite dilution. The ultrasound data have been used to calculate isentropic partial molal compressibilities which have been converted to isothermal values by using the expansibility data and literature data on partial molal heat capacities. The difference between the isentropic and isothermal partial molal compressibilities is practically zero at 5°C, and increases only slightly with temperature. Group partial molal compressibilities have been evaluated. The hydrophobic group compressibilities increase with temperature while the hydrophilic group compressibilities remain constant or decrease with temperature.
