Abstract
A process is provided for the purification of 4,4'-(9-fluorenylidene)diallylphenol. With an inclusion-compound-forming solvent which contains an inclusion-compound-forming compound capable of forming an inclusion compound with 4,4'-(9-fluorenylidene)diallylphenol, crude 4,4'-(9-fluorenylidene)diallylphenol is dissolved to form the inclusion compound in the form of a solution. The inclusion compound is then caused to deposit, for example, by charging the solution of the inclusion compound into a poor solvent for the inclusion compound, for example, an aliphatic hydrocarbon solvent such as n-hexane, n-heptane, cyclohexane or a mixture thereof.
