Sicherheit & Vorschriften

Regulatorische InformationenChemical: 2-Butenenitrile, 2-methyl-, (Z)-
Weitere SicherheitsinformationenEvaluation - Chemicals not considered for in depth evaluation - Not commercially active in Australia
DOT-KennzeichnungFlammable Liquid Poison
BrandgefahrenFlash point data for this chemical are not available, however it is probably combustible. (NTP, 1992)
GesundheitsgefahrenExcerpt from ERG Guide 131 [Flammable Liquids - Toxic]:
GefahrenübersichtEmergency treatment: AcetonitrileAcetonitrile can cause delayed onset (2-13 hours) cyanide poisoning[HSDB] See NITRILES.
Reaktive GruppeNitriles
Special ReportsKaplita PV and Smith RPToxicol Appl Pharmacol 84 (3): 533-540 (1986). Pathways for the bioactivation of aliphatic nitriles to free cyanide in mice.
Reactivity AlertsHighly Flammable
Reactivity ProfileNitriles, such as CIS-2-METHYL-2-BUTENENITRILE, may polymerize in the presence of metals and some metal compounds. They are incompatible with acidsmixing nitriles with strong oxidizing acids can lead to extremely violent reactions. Nitriles are generally incompatible with other oxidizing agents such as peroxides and epoxides. The combination of bases and nitriles can produce hydrogen cyanide. Nitriles are hydrolyzed in both aqueous acid and base to give carboxylic acids (or salts of carboxylic acids). These reactions generate heat. Peroxides convert nitriles to amides. Nitriles can react vigorously with reducing agents. Acetonitrile and propionitrile are soluble in water, but nitriles higher than propionitrile have low aqueous solubility. They are also insoluble in aqueous acids.
Air and Water ReactionsHighly flammable.
BrandbekämpfungFires involving this compound can be controlled using a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)
Erste HilfeEYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
Freisetung ohne BrandSTORAGE PRECAUTIONS: You should store this material in a refrigerator. (NTP, 1992)
Isolation and EvacuationExcerpt from ERG Guide 131 [Flammable Liquids - Toxic]:
Personal Protective Equipment (PPE)RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)
