摘要：

The identification of the calorimetric curves corresponding to liquid mixtures for different injection flows, given by a flow microcalorimeter, permits to classify in a kinetic way the studied mixtures. For this purpose, it is determined the establishment time constant of the mixture (tau(mix)) that allows us to estimate the length occupied by the dissipation (through the parameter lambda(mix)) and thus to justify the sensitivity variation obtained in different chemical calibrations.
