• synthetische

  Prepared by heating acetaldehyde ammonia in a double volume of absolute alcohol; by heating ammonia water and paraldehyde in presence of ammonium acetate.

• Definition

  ChEBI: 5-Ethyl-2-methylpyridine is a member of methylpyridines.

• Aroma threshold values

  Detection: 19 ppb

• 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

• Flammability and Explosibility

  Non flammable

• 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

• Erste Hilfe

  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.

• Lager

  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.
