Ammonium carbamate is an organic compound with the formula CH3NO2·H3N, and its systematic name is the same with the product name. With the CAS registry number 1111-78-0, it is also named as Carbamic acid, ammoniumsalt (1:1). It belongs to the product category of Industrial/Fine Chemicals. Its EINECS number is 214-185-2. In addition, the molecular weight is 78.07. This chemical is stable at common pressure and temperature, and it should be sealed and stored in a cool and dry place. Moreover, it should be protected from oxides, acids, alkali and water. This chemical will decompose slowly in the air and release ammonia, and it can slightly volatilize at room temperature and completely sublimate and decompose at the temperature of 50 °C. Moreover, it will turn into ammonium carbonate when placed in damp air or aqueous solution. When heated, it will produce urea. This chemical can be used as aluminum phosphide intermediate, and it is also used in medicine.
Physical properties of Ammonium carbamate are: (1)ACD/LogP: -1.194; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -1.94; (4)ACD/LogD (pH 7.4): -3.73; (5)ACD/BCF (pH 5.5): 1.00; (6)ACD/BCF (pH 7.4): 1.00; (7)ACD/KOC (pH 5.5): 1.00; (8)ACD/KOC (pH 7.4): 1.00; (9)#H bond acceptors: 3; (10)#H bond donors: 3; (11)#Freely Rotating Bonds: 0; (12)Polar Surface Area: 40.54 Å2; (13)Flash Point: 105.6 °C; (14)Enthalpy of Vaporization: 53.77 kJ/mol; (15)Boiling Point: 251 °C at 760 mmHg; (16)Vapour Pressure: 0.00662 mmHg at 25°C.
Preparation: this chemical can be prepared by anhydrous liquid ammonia and drikold. Moreover, 400 mL liquid ammonia can produce 200-300 g Ammonium carbamate.
Uses of Ammonium carbamate: it can be used to produce trimethylsilyl carbamate at the temperature of 20 °C. It will need solvent CHCl3. The yield is about 73%.
