The solubility of acenaphthene in benzene, 1,3-dimethylbenzene, acetone, I-propanol, and isobutanol was experimentally measured at temperatures ranging from (283.00 to 323.00) K. The laser monitoring observation technique was used to determine the disappearance of the solid phase in a solid + liquid mixture. The results of these measurements were correlated with the Apelblat equation.
