Reaction Conditions

Reaction Steps

57 parts of 1-chloroethylcarbamyl chloride are introduced into 700 parts by volume of isopropyl isocyanate at 22° C., the solution is heated to 70° C. in the course of 1.5 hours, whilst passing a slight stream of nitrogen through it, and the reaction product is condensed in a cold trap at -70° C. 12 parts (43% of theory) of vinyl isocyanate, of boiling point 38.5° C./1,013 mbar, and 0.85 part (2% of theory) of chloroethyl isocyanate, of boiling point 92° C/1,013 mbar, are obtained.
