Production
Extraction
- Extracted from spirit of hartshorn, which also contains ammonium carbonate and ammonium bicarbonate
Synthesis
- Combine liquid ammonia and dry ice
- Combine the two gases at high temperature (450–500 K) and high pressure (150–250 bar)
- Bubble the the two gases through ethanol at 0° and atmospheric pressure. The carbamate precipitates and can be separated by simple filtration.
