Title: Anthranol
CAS Registry Number: 529-86-2
CAS Name: 9-Anthracenol
Additional Names: 9-anthrol; 9-hydroxyanthracene
Molecular Formula: C14H10O
Molecular Weight: 194.23
Percent Composition: C 86.57%, H 5.19%, O 8.24%
Literature References: Prepd by dissolving anthrone in 5 to 10% boiling NaOH soln, cooling to -5° and pouring in cooled 5% H2SO4: Meyer, Ann. 379, 56 (1911). Also prepared from anthraquinone.
Properties: Needles from glacial acetic acid, plates from dil alcohol. Orthorhombic, mp 120° (if bath is heated to 110°). Sinters at 120°, mp 152° (if bath is cold at start). Absorption spectrum (of acetate): Barnett et al., J. Chem. Soc. 1928, 885. Sol in most solvents with blue fluorescence. The solid is fairly stable when kept dry. In solution it changes quickly to anthrone. Recrystallizations of anthranol may lead to a less pure compound.
