Isocyanates and their preparation using hypochlorous acid |
| abstract |
The present invention relates to a process for preparation of an isocyanate comprising (a) reacting an amide with an aqueous solution of hypochlorous acid in the presence of an water-immiscible organic solvent to produce an N-chloro amide; and (b) reacting said N-chloro amide with a base in the presence of a phase transfer catalyst and a water immiscible organic solvent to produce an isocyanate. |
