The solubility of diamantane, trimantane, tetramantane, and their derivatives in acetone, cyclohexane, ethyl acetate, toluene, heptane, and 1-pentanol was measured using the solid disappearance method for temperatures ranging from (273.15 to 348.15) K. The experimental solubility data have been correlated with different thermodynamic models to obtain engineering parameters for use in process design.
