ABSTRACT:
Aliphatic isocyanates are manufactured by thermal decomposition of aliphatic carbamic acid halides at a temperature not less than 25.degree.C above their boiling points in the presence of higher-boiling organic solvents and subsequent isolation of the resulting aliphatic isocyanate from the decomposition mixture. The isocyanates which may be manufactured by the process of the invention are valuable starting materials for the manufacture of plant protection agents, pesticides, dyes, synthetic resins and plastics, hydrophobic agents for textiles, detergents, bleaches and adhesives.
