The Solubility of n-Tetracosane (nC24) in n-Heptane (nC7) and n-Decane (nC10)

Cloud-point temperatures of n-tetracosane (nC24) dissolved in n-decane (nC10) were measured for tetracosane contents ranging from 2.9 wt.% to 20 wt.%, by the standard ASTM cloud-point test method, at atmospheric pressure. Based on this data and previously published data by Roberts et al., best-t exponential curves are established for the solubility of nC24 in nC10 and n-heptane (nC7) solvents, respectively. Below 20 wt.-% the solubility curves predict the experimental data within 5% margins. A comparison is done with nC24 in nC10 data previously published by Ashbaugh et al.
