Excess molar enthalpies of (hexane, or octane, or decane, or dodecane, or hexadecane, or cyclohexane, or 1-heptene, or 1-heptyne, or 2,2,4-trimethylpentane + ethyl 1,1-dimethylpropyl ether) at the temperature 298.15 K

Abstract

Flow-microcalorimetric measurements of excess molar enthalpies HmEat the temperature 298.15 K are reported for [x{CH3(CH2)4CH3, or CH3(CH2)6CH3, or CH3(CH2)8CH3, or CH3(CH2)10CH3, or CH3(CH2)14CH3, orc- C6C12, or CH3(CH2)4CH__CH2, or CH3(CH2)4C__CH, or (CH3)3CCH2CH(CH3)2} + (1 −x)C2H5OC(CH3)2C2H5] in order to investigate the interaction between a straight chain hydrocarbon and ethyl 1,1-dimethylpropyl ether. Over the whole composition range all the mixtures, with the exception of (1-heptene or 1-heptyne + ether), are endothermic. The experimental values are correlated by means of UNIQUAC and NRTL models.
