Souto-Caride, J. Troncoso, J. Peleteiro, E. Carballo, L. Romani] In order to study the dependence of non-universal critical quantities on the molecular structure, heat capacities per unit volume for the dimethyl carbonate+(heptane, octane, nonane, decane or tridecane) critical mixtures near their upper consolute point are measured. The data are obtained at atmospheric pressure as a function of temperature in the homogeneous and heterogeneous regions by means of a differential scanning calorimeter. The exponent and amplitudes that characterises the observed critical anomaly are determined from experimental data, being their values coherent to previous results; in addition, the critical amplitudes of the correlation length was calculated from critical amplitudes using the universality of the two-scale factor. The influence of the alkane length on the critical temperature and heat capacity critical amplitude are analysed.
