Solubility of fluorene in benzene, chloroform, acetone, 1-propanol, isobutanol, and methylbenzene 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, which can be used as a useful model in the purification process of fluorene.
