Reaction Conditions

Reaction Steps

57 parts of 1-chloroethylcarbamic acid chloride are introduced into 700 parts by volume of isopropyl isocyanate at 22° C., the mixture is heated to 70° C. in the course of 1.5 hours whilst passing a slight stream of nitrogen through it, and the reaction mixture is condensed in a cold trap at -70° C. 12 parts (43% of theory) of vinyl isocyanate of boiling point 38.5° C./1013 mbar, 0.85 part (2% of theory) of chloroethyl isocyanate of boiling point 92° C./1013 mbar and 218 parts of isopropyl isocyanate are obtained.
