90 °C

A mixture of 57 parts of 1-chloroethylcarbamyl chloride, 156 parts of ethyl isocyanate and 841 parts of hexamethylene diisocyante is heated to 90° C. in the course of 3 hours, whilst passing a stream of nitrogen at 22° C. through the mixture. A mixture of 11.8 parts (42.5% of theory) of vinyl isocyanate, of boiling point 38.5° C./1,013 mbar, 10.1 parts (23.8% of theory) of 1-chloroethyl isocyanate of boiling point 92° C./1,013 mbar and 149 parts of ethyl isocyanate is obtained in the distillation receiver.
