Isolation and Processing of Phenanthrene from Coking Tar

Аннотация

The isolation of phenanthrene from coking tar by recrystallization from a selective solvent is considered. Optimal production conditions are identified. Purified phenanthrene is obtained by recrystallization from white spirit in three stages. The oxidative processing of the purified phenanthrene is described. Applications of the oxidation products are noted. On that basis, small-scale production of more than ten products is possible.
