Abstract
By means of a DSC study, 2-bromothiophene was shown to possess three different phases which melt at atmospheric pressure. These phases, the existence of which was subsequently checked by Raman spectroscopy, were obtained reproducibly through simple thermal treatments, and melt at 196.2 K, 200.3 K and 203.9 K respectively. Their relative stabilities were established, and a nomenclature is proposed. A high pressure-temperature phase diagram pattern is suggested. Finally, premelting phenomena seem to depend on the observed phases.
