Application:
9-Fluorenone is mainly used for making synthetic resins, dyes, pesticides, preservatives, etc.
Fluorenone is an aromatic organic compound with the chemical formula C13H8O. It is used to make antimalaria drugs. It can be produced from fluorene via oxidation (by common oxidizers or even atmospheric oxygen).
Fluorenone can be produced by catalytic oxidation of fluorene, or of fluorene fractions in the presence of a quarternary ammonium salt, or by catalytic oxidative cracking (oxicracking) of a suitable aromatic.
Fluorenone's production and use as an intermediate or reagent may result in its release to the environment through various waste streams. Fluorenone is also found in fly ash from municipal incinerators, and in wood smoke and fossil fuel combustion products. If released to the atmosphere, fluorenone will exist in both the vapor and particulate phases in the ambient atmosphere based on an estimated vapor pressure of 5.7X10-5 mm Hg at 25 deg C. Vapor-phase fluorenone is degraded in the atmosphere by reaction with photochemically produced hydroxyl radicals with an estimated half-life of about 3 days.
