Resumen:
The thermal behavior of a series of organosulfur and organoselenium compounds has been studied by means of differential scanning calorimetry, X-ray diffraction, and thermomicroscopy in order to investigate their polymorphism. In this study, the polymorphism of some of the products has been established. The results of the experiments show that there are four types of thermal behavior for compounds studied. The physicochemical characterization of sulfur and selenium compounds showed differences in structural parameters and fusion temperatures among polymorphic forms.
