Resumo: | The calorimetric experiments based on technique breaking ampoule were carried out by measuring of the heat of solution of alcohol in isotonic solution (NaCl 0.10 M) and alcohol in suspension of Sc at 298 K. From these data the enthalpy of interaction alcohol with suspension of Sc (DtrsH°) was calculate by Hess law. In this study, the results indicate that the enthalpy of interaction of aliphatic alcohol (C2-C8) with suspensions of Sc is a process exothermic and becomes more exothermic with increasing of -CH2 group of alcohol in range -1,14 to -4,0 kJ.mol-1. We concluded that enthalpy of interaction shows a linear relationship with increasing of alcohol's lipophilicity, in agreement with Traube's rule. |
