Synthesis of Urea

2NH3 + CO2 → (NH2)2CO + H2O

概要

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.
