Abstract

Speed of sound and density data for dilute aqueous solutions of four branched diols derived from propane-1,3-diol (2-methyl-2-propylpropane-1,3-diol, 2,2-diethylpropane-1,3-diol, and 2-ethyl-2-butylpropane-1,3-diol) and 3-methylpentane-1,5-diol were obtained using the Anton Paar DSA 5000 vibrating-tube densimeter and sound analyzer in the temperature range from (278.15 to 318.15) K and at atmospheric pressure. Standard molar isentropic compressions and standard molar volumes were evaluated from the measured data. Present data were combined with those obtained previously for related solutes, and relations to the structures of solute molecules are discussed. The predictions of standard molar volumes based on the group contribution approach were tested and analyzed.
