5-Ethyl-2-methylpyridine Chemical Properties,Uses,Production
Chemical Properties
5-Ethyl-2-methylpyridine has a sharp penetrating aromatic aroma.
Occurrence
Reported in dry red beans, cocoa, tea, whiskey, peppermint oil, roasted and fried chicken, cocoa, coffee and cooked shrimps.
Uses
5-Ethyl-2-methylpyridine is used as specific solvent and as intermediate for several chemical reactions. Attributes PIS available on request. Please contact us. Contact
Preparation
Prepared by heating acetaldehyde ammonia in a double volume of absolute alcohol; by heating ammonia water and paraldehyde in presence of ammonium acetate.
General Description
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.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
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].
Hazard
Toxic. Corrosive and strong irritant to tis-sue.
Health Hazard
Breathing of vapors will cause vomiting and chest discomfort. Contact with liquid causes skin and eye burns.
Fire Hazard
Special Hazards of Combustion Products: Irritating vapors are generated when heated
Safety 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.
Potential Exposure
In manufacture of nicotinic acid, vinyl pyridine monomer; in intermediates for insecticides, germicides and textile chemicals
Shipping
UN23002-Methyl-5-ethylpyridine, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Incompatibilities
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.
Waste Disposal
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 observed
