Where is fluorenone found?
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 °C.
What is the Henry's law constant for fluorenone?
The Henry's Law constant for fluorenone is estimated as 6.8X10-7 atm-cu m/mole (SRC) using a fragment constant estimation method (1). This value indicates that fluorenone will volatilize from water surfaces (2,SRC). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec) is estimated as approximately 73 hours (2,SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec) is estimated as approximately 530 days (2,SRC). Fluorenone's estimated values for vapor pressure, 5.7X10-5 mm Hg (3,SRC), and Henry's Law constant (1,SRC) indicate that volatilization from dry and moist soil will not be a major fate process for this compound (SRC).
How does fluorenone release to the atmosphere?
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 °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. An estimated Koc of 2300 suggests that fluorenone will have only slight mobility in soil. Volatilization from dry and moist soil surfaces should not be a major fate process for this compound. Based on limited data, this compound may biodegrade in both soil and water. Groundwater, taken from a gasoline contaminated aquifer, was used to inoculate samples containing fluorenone as the sole carbon source; complete degradation was observed by day 11-15. In water, fluorenone is expected to adsorb to sediment and suspended matter based on its Koc value. Fluorenone may volatilize slowly from water surfaces given an estimated Henry's Law constant of 6.8X10-7 atm-cu m/mole. Estimated half-lives for a model river and model lake are 73 and 530 days, respectively. Bioconcentration in aquatic organisms may occur based on an estimated BCF value of 310; fluorenone has been detected in samples of catfish and snails. The general population may be exposed to this compound by ingestion of contaminated drinking water and inhalation of aerosols containing fluorenone. (SRC)
What is the koc of fluorenone?
The Koc of fluorenone is estimated as approximately 2300 (SRC), using a measured log Kow of 3.58 (1) and a regression-derived equation (2,SRC). According to a recommended classification scheme (3), this estimated Koc value suggests that fluorenone has only slight mobility in soil (SRC).

Why is fluorenone insoluble in water?
So why is fluorenone insoluble in water? Because even though fluorenone is polar (like water), the non-polar aspects of the molecule repel water molecules, making it unavailable for forming a solution with water. And that, class, concludes our lecture for the day on fluorenone!
What is the structure of fluorenone?
Fluorenone is an aromatic compound that contains a five-membered ring with a carbonyl group attached and two benzene rings fused on either side. Let's break that down a bit.
What is the functional group of fluorenone?
Since the carbonyl group is bonded to two other carbon atoms, the particular functional group is known as a ketone .
Is fluorenone soluble or insoluble?
If it does, we say that the compound is soluble. If it doesn't, it is insoluble.
Is fluorenone a polar compound?
Since there is an unequal sharing of the electrons between carbon and oxygen, we would say that there is a polar bond between the two, thus making fluorenone overall a polar compound. Even though the molecule is overall polar, it still has some non polar aspects as well, namely the carbon-carbon bonds and carbon-hydrogen bonds. This 'dual nature' is why it is soluble in a wide range of organic solvents.
What is the chemical formula for fluorenone?
Chemical compound. Fluorenone is an aromatic organic compound with the chemical formula C 13 H 8 O . It is used to make antimalaria drugs. It can be synthesised from fluorene with the addition of glacial acetic acid and sodium hypochlorite solution, undergoing an oxidation reaction.

How to make azafluorenone?
Azafluorenones by one step oxidation and cyclization of the corresponding alcohol which, in turn, can be prepared by Grignard reaction upon 2-bromopyridine-3-carboxaldehyde. Here, Grignard reagents were first prepared from suitably substituted halides in anhydrous diethyl ether. These freshly prepared Grignard reagents were then added to an anhydrous ethereal solution of 2-bromopyridine-3carboxaldehyde at 0 °C which yielded Heck precursors quantitatively. Alcohol was then subjected to cyclization under Heck reaction conditions in good yield.
When was the first azafluorenone synthesized?
In 1949 , Petrow and co-workers reported the first synthesis of an azafluorenone.
How many aromatic rings does 9 fluorenone have?
I would argue differently from Mike. 9-fluorenone has one polar C = O bond, but it also has two aromatic rings. Dispersion interactions are strong for such aromatic rings, and the point can be made that this factor will drive the solvation of 9-fluorenone in hexane.
Is a molecule with more than 6 carbons polar?
This is a very general rule and doesn't work in all circumstances. Thus, this molecule is not as polar.
