Abstract
Aliphatic isocyanates are manufactured by thermal decomposition of aliphatic carbamic acid halides, an inert gas being passed in during the decomposition and being removed together with the hydrogen halide formed. The isocyanates which may be manufactured by the process of the invention, particularly ethyl isocyanate, n-propyl isocyanate and isopropyl isocyanate, are valuable starting materials for the manufacture of plant protection agents, pesticides, dyes, synthetic resins, plastics, hydrophobic agents for textiles, detergents, bleaches and adhesives.
