1,1-디페닐히드라진 C화학적 특성, 용도, 생산
개요
Diphenylhydrazine is a man-made chemical that occurs in two isomeric forms: 1,1-diphenylhydrazine and 1,2-diphenylhdrazine. Diphenylhydrazine is produced by the reduction of nitrobenzene. Little or no information is available for 1,1-diphenylhydrazine. Most toxicological and use data pertain to 1,2-diphenylhydrazine.용도
Previously, 1,2-diphenylhydrazine was used for producing benzidine that was used in the synthesis of benzidine-based dyes. However, these dyes are no longer produced in the United States. The primary use of 1,2-diphenylhydrazine is in the production of the anti-inflammatory agent phenylbutazone and sulfinpyrazone, a uricosuric agent.일반 설명
Yellow crystals. Insoluble in water.공기와 물의 반응
Insoluble in water.반응 프로필
Toxic gases may be formed by mixing 1,1-DIPHENYLHYDRAZINE with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.환경귀착
Definitive information regarding the environmental fate and behavior of diphenylhydrazine in environmental media is extremely limited. No information is available affirming persistence of diphenylhydrazine in the environment or definitive pathways for its degradation. The low vapor pressure of diphenylhydrazine precludes it being a significant air contaminant. Diphenylhydrazine may be moderately absorbed into soil but it would be quickly oxidized to azobenzene. The half-life of diphenylhydrazine in water is reportedly less than 15 min and is likely due to its oxidation to azobenzene and benzidine.Purification Methods
Purify it via the hydrochloride [530-47-2], which has m 165-170o(dec) after crystallization from aqueous EtOH (+ a few drops of HCl) and recover the free base with aqueous NaOH, extract it into Et2O, dry it (KOH), filter, evaporate and distil the residue under a vacuum. The distillate crystallises on cooling. The benzoyl derivative has m 194o (from Me2CO), and the 4-nitrophenyl hydrazone (with the aldehyde) has m 131-132o.
