What is Phenylhydrazine?
Part I: Introduction
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Phenylhydrazine which has developed particularly rapidly in recent years. Do you know about Phenylhydrazine?
The official answer: Phenylhydrazine is an organic substance with the chemical formula C6H8N2, white monoclinic prismatic crystals or oily liquid with an aromatic odor, fading to yellow in the air. It is toxic. Melting point 19.5℃ (melting point 24℃ for phenylhydrazine hydrate). Boiling point 243.5℃. Relative density 1.0978. refractive index 1.60813. flashpoint 69℃. Weakly basic, Ka(15℃)1.62×10-9. miscible with ethanol, ether, benzene, etc. Slightly soluble in water and petroleum ether. It can be produced by diazotization of aniline and then reduction of NaHSO3. It is an important intermediate in the dye, medicine, and pesticide industry.
What’s the application of Phenylhydrazine?
Phenylhydrazine is the first synthetic hydrazine derivative, commonly used as organic, dyestuff, pharmaceutical, and pesticide intermediates. Organic intermediates, preparation of pyrazoline, triazole, indole, etc.; dye intermediates, preparation of diazo dye intermediates, such as 1-phenyl-3-methyl-5-pyrazolone, etc.; pharmaceutical intermediates, preparation of antipyretic, analgesic, anti-inflammatory drugs, such as antipyrine and aminopyrine, etc.; photographic drugs (photographic pigments), phenylhydrazine is also used in the production of pesticide insecticide “beaten phosphorus “Phenylhydrazine is also an important carbonyl identification reagent, used to identify aldehydes Chemicalbook, ketones, and sugars. Benzhydrazine is toxic and causes anemia and headache due to hemolytic effect after inhalation, and causes yellow bile in severe cases, and also has an irritating effect on eyes and can cause the corneal disorder. The maximum permissible concentration in the workplace is 0.44mg/m3. Laboratory uses aniline as raw material, reacts with sodium nitrite in hydrochloric acid to produce diazonium salt, then reacts with sulfurous acid and sulfur dioxide to reduce and produce sodium phenyl hydrazine sulfonate, then performs hydrochloric acid to produce phenylhydrazine hydrochloride, neutralizes and deacidifies to produce phenylhydrazine. Phenylhydrazine is used in the production of pesticides for the synthesis of organophosphorus insecticide triazophos intermediate 1-phenyl aminourea, pyridazine thiophos intermediate 1-phenyl-3,6-dihydroxypyridazine, but also fungicides new varieties of oxazolone (faChemicalbookmoxadone), imidazoline (fenamidone) intermediates, in addition, phenylhydrazine as organic synthetic raw materials. It is also used as an intermediate in dyestuff, medicine, and other industries, and as an analytical reagent. It is used as an analytical reagent and chromatographic reagent. It is used in the production of dyes, drugs, contrast agents, etc. It is an intermediate of dyestuff, medicine, and pesticide, used in the production of chromogranin AS-G, drug Antipyrine, etc. Dissolve phenylhydrazine in 95% ethanol, then add benzaldehyde and reflux for 1h to get phenylhydrazone. Phenylhydrazone is also an intermediate of organic synthesis. Phenylhydrazine is also used as an analytical reagent. It is used as a weak base to make lead, chromium and other trivalent and tetravalent elements precipitate out as hydroxide. Photometric determination of aluminum, chromium, copper, molybdenum, titanium, and zirconium. Determination of gold, iridium, molybdenum, palladium, platinum, silver. Colorimetric determination of the reducing agent of phosphoric acid. Can form phenylhydrazone with aldehyde, ketone, and sugar with different melting points, according to which these substances can be identified.
