WebThe metabolism of fluorene, a tricyclic aromatic hydrocarbon, by Cunninghamella elegans ATCC 36112 was investigated. Approximately 69% of the 9-(14)C-fluorene added to cultures was metabolized within 120 hours. The major ethyl acetate-soluble metabolites were 9-fluorenone (62%), 9-fluorenol, and 2-hydroxy-9-fluorenone (together, 7.0% ... WebApr 2, 2024 · The pollution of polycyclic aromatic hydrocarbons was serious in sediments of the Pearl River estuary, China. A fluorene-degrading bacterium, strain A2-3, was isolated from hydrocarbon contaminated sediment of this estuary and identified as Rhodococcus sp. based on the analyses of 16S rRNA gene sequence and morphology. Rhodococcus sp. A2 …

WebJun 26, 2024 · Fluorene or 9H-fluorene is a polycyclic aromatic hydrocarbon insoluble in water and soluble in many organic solvents. Is fluorene soluble in organics? Fluorene , or 9H-fluorene is an organic compound with the formula (C6H4)2CH2. It forms white crystals that exhibit a characteristic, aromatic odor similar to that of naphthalene. WebIn contrast, fluorine is too reactive, so it cannot be used directly for aromatic flourination. However, fluorinating agents like 1- (chloromethyl)-4-fluoro-1,4-diazoniabicyclo [2.2.2]octane ditetrafluoroborate (also known as F-TEDA-BF 4) sold commercially as Sectfluor® offer convenient sources of “F + ” for this type of reaction.
