| Abstract: | Excess enthalpies (H
E
) for mixtures of cyclohexanone with propan-1-ol. propan-2-ol, butan-1-ol, butan-2-ol and 2-methyl propan-1-ol at 298.15 K
have been measured over the entire composition range. All mixed endothermically with the maximum values ofH
E
occurring at equimole fraction. Comments about the molecular interactions contributing to the excess enthalpies of a cyclic
ketone + an alcohol are made on the basis of these results. |
