Measurements of sound velocity and solution density of hydroxyalkyl cellulose have been carried out at temperatures of 15, 25 and 35°C. The partial molar volume and partial molar adiabatic compressibility of hydroxyalkyl cellulose have been evaluated from these data as a function of molar substitution. The partial molar volume of hydroxyethyl and hydroxypropyl cellulose increased with the molar substitution, but they were independent of temperature. The partial molar adiabatic compressibility of hydroxyalkyl celluloses depends strongly on the structure of the substituted group and the molar substitution. The compressibility data indicate that hydroxypropyl cellulose shows a strong hydrophobic character but hydroxyethyl cellulose a weak hydrophilic one.
