2-메틸-5-에틸피리딘 C화학적 특성, 용도, 생산
화학적 성질
5-Ethyl-2-methylpyridine has a sharp penetrating aromatic aroma.출처
Reported in dry red beans, cocoa, tea, whiskey, peppermint oil, roasted and fried chicken, cocoa, coffee and cooked shrimps.용도
5-Ethyl-2-methylpyridine is used as specific solvent and as intermediate for several chemical reactions. Attributes PIS available on request. Please contact us. Contact제조 방법
Prepared by heating acetaldehyde ammonia in a double volume of absolute alcohol; by heating ammonia water and paraldehyde in presence of ammonium acetate.일반 설명
A colorless to yellow liquid. Insoluble in water and more dense than water. Hence sinks in water. Contact may slightly irritate the skin, eyes, and mucous membranes. May be toxic by ingestion. Used to make other chemicals.공기와 물의 반응
Insoluble in water.반응 프로필
5-Ethyl-2-methylpyridine neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides. A mixture of nitric acid and methyl ethyl pyridine was placed in an autoclave and heated and stirred for 40 minutes. The emergency vent opened due to a sudden pressure rise, then an explosion occurred after about 90 seconds [Chem. Eng. News 30:3348. 1952].위험도
Toxic. Corrosive and strong irritant to tis-sue.건강위험
Breathing of vapors will cause vomiting and chest discomfort. Contact with liquid causes skin and eye burns.화재위험
Special Hazards of Combustion Products: Irritating vapors are generated when heatedSafety Profile
Poison by ingestion and subcutaneous routes. Moderately toxic by skin contact. iMildly toxic by inhalation. Corrosive. A severe skin and eye irritant. Flammable when exposed to heat or flame; can react vigorously with oxidizers. Potentially explosive reaction with nitric acid at 145℃/14.5 bar. To fight fire, use alcohol foam. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALDEHYDES.잠재적 노출

UN23002-Methyl-5-ethylpyridine, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.비 호환성
Vapors may form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, aldehydes, acid chlorides; chloroformates, isocyanates, phenols, cresols.폐기물 처리
Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed2-메틸-5-에틸피리딘 준비 용품 및 원자재
