Abstract
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.
