Fluid-liquid (FL) and fluid-solid (FS) transitions are measured for tetraco
ntane in propane and calculated from an equation of state for tetracontane,
tetratriacontane, and hexacontane. The calculated data are found to be in
agreement with the experimental data. As expected, increasing the n-alkane
concentration and increasing pressure are found to increase the FS transiti
on temperature. Also, increasing the n-alkane molecular weight is found to
increase the FL transition pressure.
