Abstract
The solubility of a paraffin wax (melting point 42–43 °C) in various base oils was studied at wax concentrations up to 50 wt%. The solubility behaviour fell into two distinct regimes. In the first (wax concentration < 15
wt%), the relation between cloud point and wax concentration was more or less hyperbolic; in the second, (15–50 wt%) the relation was linear. Correlations to predict the experimental data in the two regimes are proposed, giving an average deviation of 4.2% for the first regime and 2.0% for the second.
