When reacted with concentrated nitric acid, phenol will form a trisubstituted product. The hydroxy group of phenol directs the substitution of the nitro group to the ortho and para positions of the benzene ring. Therefore, the reaction of phenol with concentrated nitric acid will produce 2,4,6...
Nitrosation is an electrophilic aromatic substitution involving the nitrosonium ion and is mainly para selective, and the oxidation is because the nitrogen dioxide in equilibrium with nitrous acid and nitric acid.doi:10.1016/S0926-9614(96)80027-XMetivier...
Chemical/Physical.In an environmental chamber, nitrogen trioxide (10,000 ppb) reacted quickly with phenol (concentration 200 ppb to 1.4 ppm) to form phenoxy radicals and nitric acid (Carter et al., 1981). The phenoxy radicals may react with oxygen and nitrogen dioxide to form quinones and ni...
Examples of acids include the inorganic substances known as the mineral acids—sulfuric, nitric, hydrochloric, and phosphoric acids—and the organic compounds belonging to the carboxylic acid, sulfonic acid, and phenol groups. Is phenol more acidic than ethanol? Phenoxide ion is aromatic and can und...
Ans. Phenol is a poor acid. In aqueous solutions within the pH range of 8-12, it is in equilibrium with the phenolate anion C6H5O- (also phenoxide). Phenol is more acidic than aliphatic compounds as it contains an OH group. The phenoxide anion is stabilized by the aromatic ring resona...
Thus, 2-propanol (CH3)2CHOH; Baker 99.5%, Ecatepec, Estado de Mexico, Mexico) and nitric acid (HNO3; Baker 99.5%, Ecatepec, Estado de Mexico, Mexico) were used as solvent and as hydrolysis catalyst. The nominal molar ratio implemented for the preparation of the support was 2-propanol/...
88The role of nitric oxide (NO) in the induction of cell death is suggested by the in vitro production of nitrite, when hemocytes are exposed to nonself molecules, and by the decrease of in vitro cytotoxicity in the presence of the NOS inhibitor Nω-nitro-l-arginine methyl ester.89The ...

Suitable inorganic oxidizing agents are, for example, halogens, such as chlorine or bromine, nitrogen oxides, nitrous acid, nitric acid or peroxides and salts of per acids, in particular hydrogen peroxide. Of particular advantage is the use of sulfur trioxide as additional oxidizing agent which ...
