9,10-phenanthrenequinone is a chemical compound from the group of ketones and polycyclic aromatic hydrocarbons . It is isomeric to anthraquinone .
Extraction and presentation
9,10-phenanthrenequinone can be obtained by liquid-phase oxidation of phenanthrene with chromates or with tert-butyl hydroperoxide , and via 9,10- phenanthrene oxide with nitric acid or hypochlorite . 9,10-phenanthrenequinone reacts like a typical α-diketone , e.g. B. When heated with aqueous alkaline solutions, it is subject to benzilic acid rearrangement with the formation of 9-hydroxyfluorene-9-carboxylic acid (flurenol).
Occurrence
9,10-phenanthrenequinone is found in coal tar , in tobacco and diesel soot .
properties
9,10-phenanthrenequinone is a flammable, hardly flammable, crystalline, dark orange, odorless solid that is practically insoluble in water. It is also easily sublimable .
use
9,10-phenanthrenequinone can be used for the passivation of silicon (100) surfaces. Like other quinones , it can also serve as a substrate for a variety of flavoenzymes . Also, in dyes, as curing agents for dentures , for the determination of copper by spectrophotometric methods for organic syntheses may be used. It is used as a printing chemical, and in paper finishing, 9,10-phenanthrenequinone is as new compositions for labeling aldehydes used, also it serves as a source of some polyannularer benzenoid systems by the Wittig reaction by means of phase transfer catalysis .
