===Extraction===
* Extracted from [[spirit of hartshorn]], which also contains [[ammonium carbonate]] and [[ammonium bicarbonate]]

===Synthesis===
* Combine liquid [[ammonia]] and [[carbon dioxide|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&deg; and atmospheric pressure. The carbamate precipitates and can be separated by simple filtration.
