Aromatic hydrocarbons, absorption radiation

Detection of certain types of compounds (for example, of an aromatic skeleton). If the compound trasmits radiation (b < 1) between 220 and 800 nm, it may well be an aliphatic or alicyclic hydrocarbon, amine, nitrile, alcohol, ether, alkyl chloride, or alkyl fluoride, but the presence of conjugated double bonds, the carbonyl group, nitro group, bromine, or iodine is excluded. The detection of the aromatic nucleus in an unknown sample is carried out by measuring the absorption in the ultraviolet region of ethanolic, cyclohexane, or /i-hexane solutions of various concentrations (10 -10 mole/liter). [Pg.82]
