Product Description

Property

CAS No.: 1111-78-0 Formula: CH6N2O2 Molecular Weight: 78.07050

Description

Ammonium carbamate is a salt formed by the reaction of ammonia with carbon dioxide or carbamic acid. This compound is a white solid that is extremely soluble in water, soluble in alcohol, and only slightly volatile at room temperature. It is prepared by the direct reaction between liquid ammonia and dry ice (solid carbon dioxide):
2 NH3(l) + CO2(s) → H2NCOONH4
