Nl. Potkina et al., Thermochemical study of the solvation of alkanes in mixtures of methanol with butyl alcohol isomers, RUSS CHEM B, 48(2), 1999, pp. 271-273
A calorimetric method was applied at 25 degrees C to measure the enthalpies
of dissolution of cyclohexane, heptane, and decane in the methanol-n-butan
ol mixed solvent and hexadecane in mixtures of methanol,with n-, iso-, and
tert-butyl alcohols. The standard enthalpies of dissolution of alkanes were
determined. It was shown that the equation proposed in the literature for
calculation of the enthalpies of dissolution of alkanes in mixtures with no
nspecific intermolecular solvent-solvent interactions describes satisfactor
ily the enthalpies of dissolution of alkanes in mixtures of methanol with n
- and iso-butyl alcohols. It was suggested that there is no preferential so
lvation of alkanes by one of the mixed solvent components in the MeOH-(BuOH
)-O-n and MeOH-(BuOH)-O-i mixtures; in the MeOH-(BuOH)-O-t system, the comp
osition of alkane solvation shell differs slightly from the solvent composi
tion in the bulk.
