Thermal deformations and polymorphous transformations of solid solutions of paraffins in C17–C19, C19–C21, C21–C23, C22–C24, and C23–C24 systems are investigated by thermal X-ray diffractometry using a temperature step of several tenths of a degree. It is examined
how the length of a molecular chain of a homolog (n) and the difference in length (Δn) between the chains as well as the molecular
composition of a solid solution affect these transitions, and the data are compared with those for the individual homologs
of paraffins.

The results of the X-ray diffraction and thermal X-ray diffraction studies of the paraffins CnH2n+2 are revised based on new principles asserting the existence of several types of rotator states of paraffins. Along with the
known isomorphism factors, such as the parity (symmetry) of the starting components and the difference between the chain lengths
of their molecules (Δn), there is a factor that is specific to paraffins: differences in the energy state of molecules entering
solid solutions.
