Chemische Eigenschaften
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.
Verwenden

synthetische
Prepared by heating acetaldehyde ammonia in a double volume of absolute alcohol; by heating ammonia water and paraldehyde in presence of ammonium acetate.
Allgemeine Beschreibung
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 Reaktionen
Insoluble in water.
Reaktivität anzeigen
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.
Brandgefahr
Special Hazards of Combustion Products: Irritating vapors are generated when heated
Sicherheitsprofil
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.
mögliche Exposition
In manufacture of nicotinic acid,
vinyl pyridine monomer; in intermediates for insecticides,
germicides and textile chemicals
Versand/Shipping
UN23002-Methyl-5-ethylpyridine, Hazard Class:
6.1; Labels: 6.1-Poisonous materials.
Inkompatibilitäten
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
