Diese Methode eignet sich auch fiir die Mononitrierung von 4-Methyl- bzw. 4-Chlor-phenol. Aus 4-Methoxy-phenol erhalt man ausschlieBlich 2,6-Dinitro-phenol. Die Nitrierung von 2-Hydroxy-naphthalin liefert 2-Hydroxy- 1-nitro-naphthalin bzw. 2,6-Dinitro-2-hydroxy-naphthalin in 68 bzw. 32%iger Ausbeute. Die Nitrierung von Hetarenen wie Pyrrol oder Indol fuhrt dagegen selbst bei — 78° zu teerartigen Produkten.

Experiments carried out by T. Urbanski, Szyc-Lewanska and Kalinowski [87] suggest the structure of 2,4-dinitro-3-(methyl)nitramino-7-(dimethyl)amino-5,5-dioxyphenothiazine (II) for the Gnehm product. The phenol produced by alkaline hydrolysis has the structure of 2,4-dinitro-3-hydroxy-7-(dimethyl)amino-5,5-dioxy-phenothiazine (III)... 

The air-water volume ratio (Va / Vw) in a cloud is about 10s (Seinfeld, 1986). Consider now a given cloud volume that contains a certain total amount of (a) 2-4-dinitro-6-methyl phenol (DNOC), and (b) 4-chloroaniline (4-CA). Calculate the fraction of total DNOC and 4-CA, respectively, present in the water phase at equilibrium at 10°C for pH 2, 4, and 6. Neglect the effect of temperature on the acidity constant. 

Some nonionic organic compounds exhibit much stronger mineral surface affinities than we see for apolar and weakly monopolar compounds like chlorobenzenes and PAHs. In these cases, the organic sorbates are able to displace water from the mineral surface and participate in fairly strong sorbate sorbent intermolecular interactions. Example compounds include mtroaromatic compounds (NACs) such as the explosive, trinitrotoluene (TNT), or the herbicide, 2,4-dinitro-6-methyl-phenol, also called dinitro-o-cresol (DNOC).

The mixture of cresols obtained from coal tar is called cresylic acid, an important technical product used as a disinfectant and in the manufacture of resins and tricresyl phosphate. Cresols are useful as raw materials for various chemical products, disinfectants, and synthetic resins. The isomer o-cresol is a starting material for the herbicides 4,6-dinitro-o-cresol and 2-methyl-4-chlorophenoxyacetic acid. The isomers w-cresol and p-cresol are used in phenol-formaldehyde resins and are converted to tricresyl phosphate (a plasticizer and gasoline additive) and to di-t-butyl cresols (antioxidants called BHT). 

Dinitro-o-cresol or 4,5-di-nitro-2-methyl phenol is an yellow crystalline compound having m.p. of 87°C (pure grade). It is pseudoacid and readily forms water-soluble ammonium potassium or sodium salts. 

DINITRO-2-METHYL PHENOL (534-52-1) Combustible solid (flash point unknown). Dust and powder form explosive mixtures with air. Thermally unstable elevated temperatures can cause explosion. May be moistened with up to 10% water to reduce the risk of explosion, or in paste form with 55—60% water. Incompatible with heat, strong oxidizers, amines, cresols, hydrocarbons, phenols. Stable at low pH, but decomposes upon UV radiation in alkaline solutions.
