실험 절차

A solution of 57 parts of 1-chloroethylcarbamyl chloride in 100 parts by volume of hexamethylene diisocyanate is introduced slowly at 100° C., in the course of half an hour, under the surface of 572 parts of hexamethylene diisocyanate. At the same time nitrogen is blown through the solution and the exit gas is cooled to -100° C. by means of a cold trap. The reaction mixture is subjected to fractional distillation. 10.2 parts (36.8% of theory) of vinyl isocyanate of boiling point 38.5° C./1,013 mbar and 6.8 parts (16.1% of theory) of 1-chloroethyl isocyanate of boiling point 92° C./1,013 mbar are obtained.
