Heat capacities, self-association and complex formation in alcohol–ester systems

Heat Capacity Measurements of 13 Methyl Esters of n-Carboxylic Acids from Methyl Octanoate to Methyl Eicosanoate between 5 K and 350 K

“…Literature data for the heat capacity and derived properties of the methyl esters on which we report here are scarce. For methyl octanoate, two sources are available 17,18 for the heat 18 the correspondence of our value is within 0.25%. For the enthalpy of fusion and or the melting points, three data sources were found.…”

Volumetric and viscometric properties of binary mixtures of {methyl tert-butyl ether (MTBE)+alcohol} at several temperatures and p=0.1MPa: Experimental results and application of the ERAS model

“…By the addition of MTBE molecules, the alcohol molecules dissociate and have greater mobility than the pure alcohols due to reduced cohesive forces of alcohol molecules upon mixing [56][57][58]. In large alcohol molecules, apart from the destruction of self-association of alcohols, there is a destruction of orientational order, resulting in large negative viscosity deviation [56,[59][60][61].…”

Heat capacities of fatty acid methyl esters from 300 K to 380 K and up to 4.25 MPa

“…Heat capacities of fatty acid alkyl esters are required for establishing enthalpy balances and the development of thermodynamic models for biodiesels [5,6]. To the best of our knowledge, there are only five sets experimental data for the heat capacities of fatty acid alkyl esters which have more than 8 carbon atoms in the fatty acid group: Deshpande et al [7] reported the heat capacity of methyl tetracaprate at 298 K; Van Bommel et al [8] reported the molar heat capacities of 13 fatty acid methyl esters from 5 K to 350 K; Zaitsau et al [9] reported the molar heat capacities of ethyl caprate from 5 K to 370 K; Pauly et al [10] reported the molar heat capacities of 7 saturated fatty acid methyl esters and 5 unsaturated fatty acid methyl esters from 250 K to 390 K; Dzida et al [11,12] reported the molar heat capacities of ethyl octanoate, ethyl caprate, ethyl laurate and ethyl tetracaprate from 285 K to 343 K. These experimental data are all measured at atmospheric pressure. For the isobaric heat capacities of methyl or ethyl esters of fatty acids at high pressure, no experimental data were reported, only Dzida et al [10,11,13] to 380 K and at pressures from 0.1 MPa to 4.25 MPa were measured with a flow calorimeter.…”
