Description
Summary:The experimental systems considered in this paper are normal alkanes, in the range from octane to octacosane; and their binary mixtures {(1−x) mol of CnH2n+2 + x mol of Cn‘H2n‘+2}, with n‘ > n, and Δn = n‘ − n taking the values 1 and 2. The alkanes and their mixtures have a rich, complex polymorphic nature, for the description of which a distinction is made between a high-temperature and a low-temperature domain. The high-temperature domain is occupied by rotator phases, and the low-temperature domain by a variety of mixed crystalline phases, referred to as the “ordered” phases. Experimental phase diagram data for 19 binariesincluding 11 binaries for which original data are presentedare used to give a uniform and coherent description of the phase relationships for the ensemble of alkane alloys.
