The densities p for binary liquid mixtures containing dipropylene glycol monopropyl ether and methanol, 1-propanol, l-pentanol and 1-heptanol have been measured as a function of composition using an Antan-Paar DSA 5000 densimeter at T=(288.15, 298.15, and 308.15) K and atmospheric pressure over the whole concentration range. The density values were used to calculate excess molar volumes V-m(E) which further allowed the following mixing quantities to be reported in all range of concentrations or at equimolar concentrations: alpha, volume expansivity; (delta V-m(E)/delta T)(P); (delta H-E/delta P)(T) at T=298.15 K. The obtained results have been compared at 298.15 K with the calculated values using the Flory theory of liquid mixtures. The theory predicts the alpha, and alpha(E) values rather well, while the calculated values of (delta V-m(E)/delta T)(P) and (delta H-E/delta P)(T) show general variation with the alkyl chain length of the n-alkanols. The results are discussed in terms of order or disorder creation. (C) 2008 Elsevier B.V. All rights reserved.
