ABSTRACT

Excess molar enthalpies have been measured for liquid binary mixtures of 2,2 -oxybis[propane] (diisopropylether DIPE ), or, benzene + butan-1-ol, +2-methylpropan-1-ol (isobutanol), +2-methyl-2-ene-1-propanol (isobutenol), +n-heptane at 303.15K and constant pressure using a C80, Setaram calorimeter. A Redlich Kister type equation was used to correlate experimental results. These experimental results, along with our previous data on excess molar enthalpies of DIPE + benzene, +cyclohexane [1] are used for estimating interaction parameters in DISQUAC, an extended quasi-chemical group contribution model [2,3].
