메타니트로톨루엔 C화학적 특성, 용도, 생산
물리적 성질
3-Nitrotoluene is a light yellow oily liquid with a nitrobenzene-like odor. The relative density is 1.1571, the melting point is 16°C, and the boiling point is 230-231°C. Almost insoluble in water, soluble in ethanol, ether, chloroform and benzene. Can volatilize with water vapor.용도
3-Nitrotoluene is mainly used in organic synthesis as an intermediate for pesticides, dyes, explosives, medicines, color developers, plastics, synthetic fibers and auxiliaries.제조 방법
3-Nitrotoluene is obtained by fractional distillation and purification after nitration of toluene with mixed acid below 50℃. Toluene nitration can get different products with different reaction conditions and catalysts, such as o-nitrotoluene, p-nitrotoluene, m-nitrotoluene, 2,4-dinitrotoluene and 2,4,6-trinitrotoluene Toluene etc.정의
ChEBI: 3-nitrotoluene is a mononitrotoluene carrying a nitro group at position 3.주요 응용
Catalytic hydrogenation or reduction with iron converts 3-nitrotoluene to m-toluidine, which provides important coupling components for azo dyes, usually after N-alkylation.일반 설명
Yellow crystals that melt at 59°F to a yellow liquid. Often therefore encountered as a liquid. Flash point 223°F. Boiling point 450°F. Insoluble in water. Toxic by inhalation and ingestion.공기와 물의 반응
Insoluble in water.반응 프로필
3-Nitrotoluene reacts with sulfuric acid, strong oxidizing agents and reducing agents.위험도
Toxic by inhalation, ingestion, skin absorption. Methemoglobinemia. Probable carcinogen.건강위험
INHALATION, INGESTION OR SKIN ABSORPTION: Headache, flushing of face, dizziness, difficult breathing, cyanosis, nausea, vomiting, muscular weakness, increased pulse and respiratory rate, irritability and convulsions. EYES: Slight irrita- tion. SKIN: Slight irritation.잠재적 노출
The nitrotoluenes are used in the production of toluidines and other dye intermediates. All isomers are used in manufacture of agriculture and rubber chemicals and in various dyes.환경귀착
Biological. Under anaerobic conditions using a sewage inoculum, 3-nitrotoluene and 4- nitrotoluene both degraded to toluidine (Hallas and Alexander, 1983). Robertson et al. (1992) reported that toluene dioxygenases from Pseudomonas putida F1 and Pseudomonas sp. Strain JS 150 oxidized the methyl group forming 3-nitrobenzyl alcohol.운송 방법
UN1664 Nitrotoluenes, (o-; m-; p-), Hazard Class: 6.1; Labels: 6.1-Poisonous materials.Purification Methods
Dry 3-nitrotoluene over P2O5 for 24hours, then fractionally distil it under reduced pressure. [Clark & Taylor Org. Synth Coll Vol I 415 1941, Beilstein 5 IV 847.]비 호환성
Decomposes on contact with strong oxidizers; strong acids; reducing agents; strong bases; ammonia, amines producing toxic fumes, causing fire and explosion hazard. Heat above 190C may cause explosive decomposition. Attacks some plastics, rubbers, and coatings.폐기물 처리
Controlled incineration-care must be taken to maintain complete combustion at all times. Incineration of large quantities may require scrubbers to control the emission of nitrogen oxides.메타니트로톨루엔 준비 용품 및 원자재
