Ammonium carbamate, known by its CAS number 1111-78-0, is a fascinating chemical compound whose synthesis and equilibrium behaviors are central to its industrial and research applications. Formed through the reaction of ammonia (NH₃) and carbon dioxide (CO₂), this compound exists in a dynamic equilibrium with its constituent gases. This intrinsic property is key to its role as an intermediate in urea production and its utility in various chemical processes. NINGBO INNO PHARMCHEM CO.,LTD., a reputable supplier in China, offers high-purity ammonium carbamate that reflects a deep understanding of these chemical principles.

The synthesis of ammonium carbamate can be achieved by reacting gaseous ammonia and carbon dioxide under specific conditions, or more simply, by reacting liquid ammonia with dry ice (solid carbon dioxide). The equilibrium can be represented as: [NH₄][NH₂CO₂] ⇌ 2 NH₃ + CO₂. This equilibrium shifts towards the carbamate at lower temperatures and favors dissociation at higher temperatures. In aqueous solutions, it further equilibrates with ammonia, carbon dioxide, bicarbonate, and carbonate ions, making its behavior in solution quite complex. Understanding these equilibria is vital for controlling reactions and maintaining product stability.

At elevated temperatures, ammonium carbamate can condense to form urea and water: [NH₄][NH₂CO₂] → (NH₂)₂CO + H₂O. This dehydration reaction is fundamental to the industrial production of urea fertilizer. The efficiency of this conversion relies heavily on the quality of the ammonium carbamate used.
