Variation of volumic properties with temperature and composition of 2-butanone+1,2-propanediol binary mixtures

In this work we present experimental values of the density (rho), and some related quantities such as excess molar volumes (V-E), of the 2-butanone 1,2-propanediol binary mixtures at various temperatures in the -10 less tha n or equal to t / degreesC less than or equal to 80 range and as a function of mole fraction. The experimental results have been fitted to some relati onships of the type rho = rho (T), rho = rho (x(i)), and rho = rho (T,x(i)) to estimate the property in correspondence of the experimental data gaps. The observed behaviour has been interpreted on the basis of specific intera ctions and molecular features of the components. (C) 2000 Elsevier Science B.V. All rights reserved.
