摘要: Abstract Excess molar enthalpies HmE and excess volumes VmE at 298.15 K are reported for binary mixtures of hexane isomer (1-hexane (Hx), 2-methylpentane (2MP), 3-methylpentane (3MP), 2,3-dimethylbutane (23DMB), 2,2-dimethylbutane (22DMB)) + cyclohexane (CH). The results endothermic in the whole concentration all mixtures. On other hand, positive Hx system, negative 23DMB 22DMB systems change to with increase mole fraction x 2MP 3MP systems. values (x=0.5) large order HX>2MP>3MP>23DMB>22DMB. This is reverse those decalin isomer+hexane our group previously [Fluid Phase Equilib. 46 (1989) 59]. These were explained by using Flory theory from solvation enthalpy one component component. these tend same as except 3MP. differences free volume geometric packing between molecules. liquid correlated partial infinite dilution.
