Chemische Eigenschaften
Amyl nitrites are flammable, yellowish liquid
with a penetrating, fruity odor.
Definition
ChEBI: A nitrite ester having n-pentyl as the alkyl group.
Allgemeine Beschreibung
Amyl nitrite, isopentyl nitrite [(CH
3)
2CHCH
2CH
2ONO], isa mixture of isomeric amyl nitrites but is principally isoamylnitrite. It may be prepared from amyl alcohol and HNO
2 byseveral procedures. Usually, amyl nitrite is dispensed in ampul form and used by inhalation or orally in alcohol solution.Currently, it is recommended for treating cyanide poisoning;although not the best antidote, it does not require intravenousinjections.
Amyl nitrite is a yellowish liquid with an ethereal odor anda pungent taste. It is volatile and inflammable at room temperature.Amyl nitrite vapor forms an explosive mixture in air oroxygen. Inhalation of the vapor may involve definite explosionhazards if a source of ignition is present, as both roomand body temperatures are within the flammability range ofamyl nitrite mixtures with either air or oxygen. It is nearly insolublein water but is miscible with organic solvents. The nitritealso will decompose in valeric acid and nitric acid.
Air & Water Reaktionen
Highly flammable. Decomposes on exposure to air, light, or water. Many, but not all, will be colorless flammable toxic gases. Insoluble in water. Reaction with moisture in air or with water produces nitric acid.
Reaktivität anzeigen
Pentyl nitrite is an oxidizing agent. May begin a vigorous reaction that culminates in a detonation if mixed with reducing agents, including hydrides, sulfides and nitrides.
Health Hazard
Inhalation or ingestion causes flushing of the face, pulsatile headache, disturbing tachycardia, cyanosis (methemoglobinemia), weakness, confusion, restlessness, faintness, and collapse. Contact with eyes or skin causes irritation.
Sicherheitsprofil
Moderately toxic by
inhalation and ingestion. Causes flushing of
skin, rapid pulse, headache, and fall in blood
pressure. Mutation data reported. See also
NITRITES and ESTERS. Flammable when
exposed to heat or flame or by spontaneous
chemical reaction. To fight fire, use alcohol
foam. An oxidizing material. Vapors
explode when heated. It will react with
oxidizing or reducing materials. When
heated to decomposition it emits toxic
fumes of NOx.
mögliche Exposition
Amyl nitrite is used to make pharmaceuticals;
perfumes, diazonium compounds, and other
chemicals.
Versand/Shipping
UN1993 Flammable liquids, n.o.s., Hazard
Class: 3; Labels: 3-Flammable liquid, Technical Name
Required.
Inkompatibilitäten
Vapors may form explosive mixture with
air. Slowly decomposes in light, heat, and on contact with
water. A strong oxidizer. Contact with reducing agents and
easily oxidizable materials may cause fire and explosions.
Reported to be an explosion hazard when exposed to air and
light. Keep away from alcohols, antipyrine, alkaline materials;
alkaline carbonates; potassium iodide; bromides, and ferrous
salts. Attacks metals in the presence of moisture.
Waste disposal
Incineration with scrubber to
remove nitrogen oxides from the combustion gases.
