摘要：

Using differential scanning calorimetry (d.s.c.) apparatus, an experimental procedure has been developed in order to determine the wax content of 29 crude oils from several sources. The amount of wax, which is obtained with good reproducibility, is higher than the values obtained by gas chromatography (g.c.). In fact, g.c. evaluates n-alkanes and d.s.c. evaluates the total amount of crystallized species (n-alkanes isoalkanes, cycloalkanes,...,). The tested method is rapid, each run is performed within 1 h.
