The excess molar volumes VmE for binary liquid mixtures containing dipropylene glycol monomethyl ether or dipropylene glycol monobutyl ether and methanol, 1-propanol, 1-pentanol and 1-heptanol have been measured as a function of composition using a continuous dilution dilatometer at T=(288.15, 298.15, and 308.15) K and atmospheric pressure over the whole concentration range. The excess volume results allowed the following mixing quantities to be reported in all range of concentrations or at equimolar concentrations: , volume expansivity; (VmE/T)p; (HE/P)T at T=298.15 K. The obtained results have been compared at T=298.15 K with the calculated values by using the Flory theory of liquid mixtures. The theory predicts the , and E values rather well, while the calculated values of (VmE/T)p and (HE/P)T show general variation with the alkyl chain length of the alkoxypropanols. The results are discussed in terms of order or disorder creation.
