5-Ethyl-2-methylpyridine Chemical Properties,Usage,Production
Uses
5-Ethyl-2-methylpyridine is found in alcoholic beverages. 5-Ethyl-2-methylpyridine is present in dry red beans, cocoa, tea and whisky. 5-Ethyl-2-methylpyridine is a flavouring agent. 5-Ethyl-2-methylpyridine is one of the components that contribute to the nutty, roasted aroma in the Parmigiano-Reggiano cheese.
Description
2-Methyl-5-ethyl pyridine is a colorless liquidwith a sharp, aromatic odor. Molecular weight = 121.20;Boiling point = 128℃; Flash point = 39℃; also listed at68℃; Autoignition temperature 5 538℃. Explosive limits:LEL 5 1.1%; UEL 5 6.6%. Hazard Identification (based onNFPA-704 M Rating System): Health 2, Flammability 2,Reactivity 0. Slightly soluble in water.
Chemical Properties
2-Methyl-5-ethyl pyridine is a colorless liquid with a sharp, aromatic odor.
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
Perfume composition
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
Definition
ChEBI: 5-Ethyl-2-methylpyridine is a member of methylpyridines.
Preparation
Prepared by heating acetaldehyde ammonia in a double volume of absolute alcohol; by heating ammonia water and paraldehyde in presence of ammonium acetate.
Aroma threshold values
Detection: 19 ppb
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
Flammability and Explosibility
Non flammable
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
First aid
If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek med-ical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, includ-ing resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medi-cal attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.Medical observation is recommended for 24- -48 h afterbreathing overexposure， as pulmonary edema may bedelayed. As first aid for pulmonary edema, a doctor orauthorized paramedic may consider administering a cortico-steroid spray.
storage
Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling andstorage. Before entering confined space where this chemicalmay be present, check to make sure that an explosive concentration does not exist. Store in tightly closed containersin a cool, well-ventilated area away from oxidizers. Wherepossible, automatically pump liquid from drums or otherstorage containers to process containers. Sources of ignition, such as smoking and open flames, are prohibitedwhere this chemical is handled, used, or stored. Metal containers involving the transfer of 5 gallons or more of thischemical should be grounded and bonded. Drums must beequipped with self-closing valves, pressure vacuum bungs,and flame arresters. Use only nonsparking tools and equipment, especially when opening and closing containers ofthis chemical. Wherever this chemical is used, handled,manufactured, or stored, use explosion-proof electricalequipment and fittings.
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
