Abstract: To prepare hexamethylene diisocyanate, hexamethylene dialkyl urethanes are evaporated at temperatures from 220 to 300 DEG C, advantageously under reduced pressure, without decomposition, the vapours are subsequently cleaved thermally in the gas phase at temperatures above 300 DEG C and under a pressure of 0.1 to 100 mbar, and the cleavage products are subjected to fractional condensation, the first condensation step giving mostly hexamethylene diisocyanate and the second condensation step giving the alcohol.
