Synthesis of Urea

2NH₃ + CO₂ → (NH₂)₂CO + H₂O

Descripción general

Ammonia reacts with carbon dioxide at high temperature and pressure to form urea and water. This is the Bosch-Meiser process, which produces the most widely used nitrogen fertilizer. The first synthetic organic compound was urea, famously synthesized by Wohler in 1828.
