|Title:||Experimental And Predicted Mixing Enthalpies For Several Methyl Normal-Alkanoates With Normal-Pentane At 298.15-K - Application Of The Unifac Model||Authors:||Ortega, J
|Issue Date:||1992||Publisher:||0040-6031||Journal:||Thermochimica Acta||Abstract:||Mixing enthalpy values for nine binary systems consisting of methyl esters (from ethanoate to n-decanoate) and n-pentane measured at 298.15 K and normal atmospheric pressure using a Calvet microcalorimeter are reported. The experimental results showed that the h(E) values are positive over the entire range of concentrations and that they decrease in a regular manner as the ester chain-length increases. The experimental values were compared with predictions obtained by applying the UNIFAC model using various options. Mean estimation errors for the nine systems ranged between 7.1% and 25.6%, depending on the individual model case applied.||URI:||http://hdl.handle.net/10553/53826||ISSN:||0040-6031||Source:||Thermochimica Acta[ISSN 0040-6031],v. 195, p. 321-327|
