Fluid−Liquid and Fluid−Solid Transitions of Tetracontane in Propane

Fluid−liquid (FL) and fluid−solid (FS) transitions are measured for tetracontane 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...

Description
Summary:Fluid−liquid (FL) and fluid−solid (FS) transitions are measured for tetracontane 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 transition temperature. Also, increasing the n-alkane molecular weight is found to increase the FL transition pressure.
