diphenylamine การใช้

• Superficial scald may be controlled by treatment with diphenylamine before storage.
• The carcinogen 4-Aminobiphenyl can accompany diphenylamine as an impurity.
• Krupp began adding diphenylamine as a stabilizer in 1888.
• Diphenylamine is one of the most common stabilizers used.
• Metabolism of 14C-diphenylamine in stored apples nature of the residue in plants.
• Illustrated is the reduction of phenothiazine to diphenylamine:
• Pressurized alcohol removed remaining water from drained pyrocellulose prior to mixing with ether and diphenylamine.
• Diphenylamine dissolves well in many common organic solvents, and is moderately soluble in water.
• Diphenylamine is known to be used to make phenothiazine based drugs, eg promazine and diethazine.
• The plans originally called for production lines to make smokeless powder, diphenylamine, and sulfuric acid.
• Following this, crude tyramine was procured by heating tyrosine in the presence of the catalyst diphenylamine.
• Nitrated analogs of diphenylamine formed in the process of stabilizing decomposing powder are sometimes used as stabilizers themselves.
• Diphenylamine has low acute and short-term toxicity to birds, but is very toxic to aquatic organisms.
• While N-methyl-p-nitroaniline ( MNA also used in IMX-101 ), and diphenylamine ( DPA ) are more commonly employed.
• McCarty's arrival at Rockefeller University was also marked by another milestone, namely, the development of a diphenylamine reagent assay to positively correlate DNA with biological activity.
• The'European Diphenylamine Task Force'resubmitted an application to the EC with more data, and an additional report was received by the EFSA on 3 December 2010.
• The compound was originally prepared by Bernthsen in 1883 via the reaction of diphenylamine with sulfur, but more recent syntheses rely on the cyclization of 2-substituted diphenyl sulfides.
• Diphenylamine derivatives, such as ring-alkylated derivatives of diphenylamine are used as anti-ozonants in the manufacture of rubber products, reflecting the antioxidant nature of aniline derivatives.
• Diphenylamine derivatives, such as ring-alkylated derivatives of diphenylamine are used as anti-ozonants in the manufacture of rubber products, reflecting the antioxidant nature of aniline derivatives.
• Suspected samples can be tested for phosgene using filter paper ( treated with 5 % diphenylamine, 5 % dimethylaminobenzaldehyde in ethanol, and then dried ), which turns yellow in phosgene vapor.
