Methylvinylnitrosamine Chemische Eigenschaften,Einsatz,Produktion Methoden

Chemische Eigenschaften
N-Nitrosomethylvinylamine is a yellow liquid.
Verwenden
N-Methyl-N-nitroso-ethenamine is used as research reagent for base induced fragmentation to give aldehydes or ketones and smaller alkylnitrosamine
Verwenden
N-nitrosomethylvinylamine is used as a research chemical; no other uses were identified (IARC 1978, HSDB 2009).
Vorbereitung Methode
NMVA has not been produced commercially and is currently produced in limited quantities for research purposes. There are no reports that it occurs in the environment and exposure is likely limited to researchers using NMVA.
Definition
ChEBI: N-Nitrosomethylvinylamine is a nitroso compound.
Allgemeine Beschreibung
Very volatile yellow liquid.
Air & Water Reaktionen
Water soluble but relatively unstable in water .
Health Hazard
ACUTE/CHRONIC HAZARDS: Methylvinylnitrosamine is highly toxic by ingestion and inhalation. When heated to decomposition, Methylvinylnitrosamine emits toxic fumes of NOx.
Brandgefahr
Flash point data for Methylvinylnitrosamine are not available; however Methylvinylnitrosamine is probably combustible.
Sicherheitsprofil
Confirmed carcinogen with experimental tumorigenic data. Poison by ingestion and inhalation. When heated to decomposition it emits toxic fumes of NOx. See also N-NITROSO COMPOUNDS and AMINES.
mögliche Exposition
This chemical is not manufactured but occurs as a chemical reaction byproduct found in the dye, automotive, rubber, and leather industries.
Carcinogenicity
N-Nitrosomethylvinylamine is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
Versand/Shipping
UN3082 Environmentally hazardous substances, liquid, n.o.s., Hazard Class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required
Inkompatibilitäten
Light sensitive. 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. A nitrated amine. Amines are combustible. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.
Waste disposal
Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
