UreaSynthese
Urea synthesis refers to chemical processes used to produce urea, a colorless, crystalline compound with formula CO(NH2)2. Urea is a major nitrogen-containing chemical used as a fertilizer, a chemical intermediate, and a precursor for resins and various polymers.
Historically, the first synthesis was demonstrated by Friedrich Wöhler in 1828, who converted ammonium cyanate into
Industrial production is dominated by the Bosch–Meiser process. Ammonia reacts with carbon dioxide under high pressure
Urea’s high nitrogen content, solubility, and favorable production cost make it the world's most widely used
Safety and environmental considerations are modest but important. Urea is relatively low in acute toxicity, though
