The most widely used compounds are diisocyanates, which contain two isocyanate groups, and polyisocyanates, which are usually derived from diisocyanates and may contain several isocyanate groups.
Where are isocyanates found?
A: Isocyanates are commonly found in automotive paints, foam cushions, mattresses, car seats, foam insulation, foam packaging materials, under-carpet padding, polyurethane rubber and adhesives.
How is isocyanate made?
Isocyanates are produced from amines by phosgenation, i.e. treating with phosgene: RNH2 + COCl2 → RNCO + 2 HCl. These reactions proceed via the intermediacy of a carbamoyl chloride (RNHC(O)Cl). Owing to the hazardous nature of phosgene, the production of isocyanates requires special precautions.
