A mixture of 160 parts of 1-chloroethylcarbamic acid chloride and 537 parts of α-pinene is heated at from 124° to 105° C. in the course of 2 hours, whilst stirring, and the reaction mixture is then subjected to fractional distillation. A total of 27.6 parts (23% of theory) of 1-chloroethyl isocyanate of boiling point 92° C./1013 mbar and 34.6 parts of vinyl isocyanate of boiling point 38.5° C./1013 mbar is obtained.
