Abstract

Speed of sound data for dilute aqueous solutions of one monohydric alcohol (2,2-dimethylpropane-1-ol), five polyhydric alcohols (2-methylpropane-1,3-diol, 2,2-dimethylpropane-1,3-diol, 2,2-bis(hydroxymethyl)propane-1-ol, 2,2-bis(hydroxymethyl)propane-1,3-diol, 2,2-bis(hydroxymethyl)butane-1-ol), and one ether alcohol (3,3,7,7-tetrakis(hydroxymethyl)-5-oxanonane) 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 were evaluated from the measured data. Measured densities of dilute aqueous solutions of 2,2-dimethylpropane-1,3-diol and 2,2-bis(hydroxymethyl)propane-1,3-diol are also presented along with the standard molar volumes of these two solutes calculated from the measured data. Relations between the two standard quantities and molecular structures of the solutes are discussed.
