Health Hazard
Exposures to 2-acetylfl uorene cause irritations to the eyes, skin, respiratory tract, and digestive tract. The toxicological properties have not been fully investigated.
Lager
2-Acetylfl uorene should be stored in a cool, dry place, in a tightly sealed container.
läuterung methode
Crystallise acetylfluorene from EtOH (solubility is 60g/800mL) or Me2CO (solubility is 60g/400mL). The oxime [110827-07-1] has m 192-193.5o and the 2,4-dinitrophenylhydrazone [109682-26-0] has m 261-262o. [Ray & Rieveschl Org Synth Coll Vol III 23 1973.]
Vorsichtsmaßnahmen
Occupational workers should avoid exposures to 2-acetylfl uorene and breathing dust, vapor, mist, or gas. They should avoid contact with the skin and eyes, and avoid ingestion and inhalation. Workers should wear appropriate protective gloves to prevent skin exposure and chemical-splash goggles.
