Exempel på hur man kan använda NITROBENZENE i en mening

• Sverdlov Plant, FSE (Federal State Enterprise) manufactures munitions, battle and industrial explosives, and chemicals for industrial purposes (phenol-formaldehyde resin, epoxy resin, carbamide-furane resin, plasticizers, hardeners of various modifications, nitrobenzene, sulphanole, acetic anhydride, various cleaners and detergents, as well as other products).
• There are many major industrial applications of nitration in the strict sense; the most important by volume are for the production of nitroaromatic compounds such as nitrobenzene.
• In one quantitative study, the reduction of nitrobenzene to aniline receives 64 points out of 100 marking it as an acceptable synthesis overall whereas a synthesis of an amide using HMDS is only described as adequate with a combined 32 points.
• Anisole undergoes electrophilic aromatic substitution reaction at a faster speed than benzene, which in turn reacts more quickly than nitrobenzene.
• Traditionally, these reactions require high-boiling, polar solvents such as N-methylpyrrolidone, nitrobenzene, or dimethylformamide and high temperatures (often in excess of 210 °C) with stoichiometric amounts of copper.
• A classic named reaction is the Piria reaction (Raffaele Piria, 1851) in which nitrobenzene is reacted with a metal bisulfite forming an aminosulfonic acid as a result of combined nitro group reduction and sulfonation.
• Fallenstein, It consisted of nitrobenzene thickened or gelatinised by the addition of some collodion-cotton incorporated with finely ground potassium chlorate and precipitated antimony sulphide.
• Azoxybenzene and its derivatives are typically prepared by reduction of nitrocompounds, such as the reduction of nitrobenzene with arsenous oxide.
• Alternatively, the partial hydrogenation of nitrobenzene affords phenylhydroxylamine, which rearranges primarily to 4-aminophenol (Bamberger rearrangement).
• These species may account for the fact that moderately and strongly deactivated substrates that are inert to Friedel-Crafts reactions like acetophenone, nitrobenzene and p-chloronitrobenzene do show marginal reactivity of limited synthetic utility under chloromethylation conditions.
• The reaction was first used by Antoine Béchamp to reduce nitronaphthalene and nitrobenzene to naphthylamine and aniline, respectively.
• Products include: aniline, caustic soda, chlorine, chlorobenzene, nitrochlorobenzene, nitrobenzene, vinyl chloride monomer (VCM).
• Ferris, Emmons reported that in situ generated trifluoroperacetic acid was capable of oxidising aniline to nitrobenzene, an observation which pioneered the applications of this peroxy acid as an oxidising agent in organic chemistry.
• Usually, one electrolyte is an aqueous electrolyte composed of hydrophilic ions such as NaCl dissolved in water and the other electrolyte is a lipophilic salt such as tetrabutylammonium tetraphenylborate dissolved in an organic solvent immiscible with water such as nitrobenzene, or 1,2-dichloroethane.
• Pentachloronitrobenzene, typically abbreviated PCNB, is a registered fungicide formally derived from nitrobenzene.
• Also included are the aromatic nitro-, amino-, and pyridilium-deratives: nitrobenzene, dinitrobenzene, trinitrotoluene, paramethylaminophenol sulfate (Metol), dinitro-ortho-cresol, aniline, trinitrophenylmethylnitramine (tetryl), hexanitrodiphenylamine (aurantia), phenylenediamines, and paraquat.
• Liquid non-self-explosive sensitizers like nitrobenzene and liquid nitrotoluene have not worked well either because they are difficult to hold in suspension.
• This reaction occurs at high temperatures in organic solvents including cresol, nitrobenzene, benzonitrile, and sulfolane.
• the contaminated land in the vicinity of the plants which used to manufacture nitrobenzene, toluenediamine (TDA), toluene diisocyanate (TDI) and dinitro (DNT).
• More complicated but more biorelevant routes involve degradation of precursors such as nitrobenzene and phenylhydroxylamine.
