Реферат:	eng: Orthorhombic (s.g. P 21 21 2, a = 28.6145 Å, b = 27.4115 Å, c = 6.9536 Å, V = 5454.1 Å3) betulin (C30H50O2) was found in this study to melt at 245 C with the enthalpy of fusion 40.3 J mol-1. The shape of the peak of melting gives rise to the belief that there are several polymorphs of betulin. © 2012 Akadémiai Kiadó, Budapest, Hungary.
