The thermodynamic properties of thianthrene and phenoxathiin

Excess properties and vapour pressure of (3-diethylaminopropylamine+n-alkanes)

“…The performance of the apparatus was checked by determining H E of (n-hexane + cyclohexane), at T = 298.15 K, our results differ by less than 2% from those reported in the literature by Marsh [28]. Table 1 shows the molar volumes of the pure compounds (3-DEPA and n-heptane) estimated with the Rackett correlation using the literature data for acentric factor and critical properties [29] and the mixed virial coefficients together with the experimental vapour pressures. The virial coefficients of the diamine were evaluated from Pitzer correlation [30].…”
