Experimental Properties:Freely sublimes at room temperature|These compounds are all hydrolyzed using 5 M sodium hydroxide solution, although the reaction times vary. Methyl carbamate is hydrolyzed to methanol and carbamic acid and urethane /ethyl carbamate/ is hydrolyzed to ethanol and carbamic acid. ... Carbamic acid decomposes to carbon dioxide and ammonia ... In all cases destruction is greater than 99% and good accountances are obtained for the products ... .
Air and Water Reactions:Water soluble.
Reactive Group:Carbamates
Reactivity Profile: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.
