COMPRESSIONS OF (WATER+A-C3-ALKANOL) AND (WATER+AN-ALKAN-1,2-DIOL) AT THE TEMPERATURE 298.15-K AND PRESSURES UP TO 200MPA

Compressions of {water + (propan-1-ol or propan-1,3-diol or glycerol or ethan-1,2-diol or propan-1,2-diol)} at the temperature 298.15 K and pressures up to 200 MPa have been measured over the whole range of composition. Experimental compressions as a function of pressure for mixtures of fixed composition were fitted to the Tait equation; the values of the Tait parameters evaluated, together with available densities at 0.1 MPa for each mixture, were used to calculate the isothermal compressibility. The composition dependences of isothermal compressibilities and excess molar volumes for the mixtures are discussed from the viewpoint of the effect of changing hydrophobic character of the alkanol molecules. © 1990.
