✦ Synopsis

Differential scanning calorimetry (d.s.c.) has been used to characterize crude petroleum. A thermal fingerprint can be obtained in a short time with a single experiment. Several parameters such as the glass transition temperature q ofthe hydrocarbon matrix, temperature of crystallization and paraffins content can be measured with good reproducibility. For the same crude, a correlation has been found between T and T, for distillates prepared following ASTM method D2892.
