摘要: Abstract Experimental results are reported of excess molar volumes VmE and enthalpies HmE at T=313.15 K for twelve binary mixtures alkanols (ethanol, 1-butanol or iso-butanol) alkanes (n-heptane, iso-octane (2,2,4-trimethylpentane) n-octane) with butyl-vinyl ether iso-butyl-vinyl ether. A vibrating-tube densitometer was used to determine VmE. The quantity measured using a quasi-isothermal flow calorimeter. applicability the ERAS model has been investigated describing thermodynamic properties different temperatures. reveal effect temperature molecular structure on ability an molecule form alkanol–ether associates.
