Thermodynamic study of interactions between Dimethyl Carbonate and a homologous series of ۲- Alkanols

The thermodynamic and excess molar properties of liquids and liquid mixtures have been used to understand the molecular interactions between the components of the mixture and also for engineering applications. The thermodynamic study of esters of carbonic acid holds considerable interest owing to their uses in industry for the synthesis of many chemicals, in pharmaceuticals, and in agricultural chemistry. Such chemicals are also used as extractive solvents [۱-۲].Densities of binary mixtures of dimethyl carbonate with ۲-Propanol, ۲-Butanol , ۲-Pentanol, ۲-Hexanol and ۲- Heptanol at temperatures: ۲۹۸.۱۵ K , ۳۰۳.۱۵ K , ۳۰۸.۱۵ and ۳۱۳.۱۵K were measured at the whole range of mole fraction. Excess molar volumes(V mE ) were correlated by Redlich-Kister type equation as a function of temperature [۳].
