Chemische Eigenschaften
Methyl carbamate is a white, adhesive crystal. It is highly soluble in water, as well as in ethanol, acetone, and other organic solvents.
Verwenden
Methyl carbamate was used in the synthesis of protected aminocyclopropanes.
Definition
ChEBI: Methyl carbamate is a carbamate ester resulting from the formal condensation of the carboxy group of carbamic acid with methanol.
Allgemeine Beschreibung
Methyl carbamate appears as white to Almost white powder to crystal. It an intermediate in the manufacture of dimethylol methyl carbamate-based resins, which are used in the textile industry as durable-press fabric finishes for polyester/cotton blends.
Air & Water Reaktionen
Water soluble.
Reaktivit?t anzeigen
Methyl carbamate is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.
Brandgefahr
Flash point data for Methyl carbamate are not available; however, Methyl carbamate is probably combustible.
Sicherheitsprofil
Poison by ingestion and
intraperitoneal routes. Questionable
carcinogen with experimental carcinogenic
and tumorigenic data. Mutation data
reported. When heated to decomposition it
emits toxic fumes of NOx. See also
CARBAMATES.
l?uterung methode
