実験手順
A solution of 970 parts of isopropylcarbamic acid chloride in 1,020 parts of chlorobenzene is inroduced into an apparatus analogous to that of Example 1 and is refluxed for 9 hours -- during which the reaction temperature rises from 77° to 88° C -- whilst passing 120,000 parts by volume of dry nitrogen per hour through the mixture. The subsequent distillation gives 630 parts of isopropyl isocyanate free from carbamic acid chloride (corresponding to 93% of theory, based on isopropylcarbamic acid chloride used), boiling at from 73.5° to 74.5° C.
