Ce dispositif permet d’obtenir des enthalpies molaires partielles de mélange H: et molaires apparentes relatives qL,. Un contrôle par ordinateur et un traitement numérique des thermogrammes permet d’atteindre facilement tout le domaine de concentrations jusqu’à de très grandes dilutions (0.001 6 x, 6 0,999). An experimental set-up for heat flux conduction calorimetry with improved applications in liquid mixture studies by continuous titration is presented. The experimental system is controlled by a personal computer. Sophisticated signal processing determines the partial excess enthalpies HiE or relative apparent molar enthalpies phi Li over the entire range of concentration, including the high dilution domain (0.001<or=xi<or=0.999). |
