Excess molar enthalpies of diethyl malonate+ (1-butanol, 2-methyl-1-propanol, 1-pentanol, n-heptane, and ethyl acetate) at T= (288.2, 298.2, 313.2, 328.2, 338.2, and 348.2 K) and p=101.3 kPa
A flow-mixing isothermal microcalorimeter has been used to determine the excess molar enthalpies for five binary systems of diethyl malonate+ (1-butanol, 2-methyl-1-propanol, 1-pentanol, n-heptane, and ethyl acetate) at T= (288.2, 298.2, 313.2. 328.2, 338.2, and 348.2 K) and p = 101.3 kPa. The H-m(E) values increase with increasing temperature. The experimental data have been correlated by the Redlich-Kister equation and two local composition models (NRTL and UNIQUAC).
