Partial Molar Isentropic Compressions and Partial Molar Volumes of Selected Branched Aliphatic Alcohols at Infinite Dilution in Water at Temperatures from T = (278 to 318) K and Atmospheric Pressure

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 standard quantities and molecular structures of the solutes are discussed.
