Abstract:
The invention relates to a method for producing isocyanates by reacting primary amines with phosgene in a stoichiometric excess in the gas phase, wherein the excess phosgene is subsequently recovered and recirculated back into the reaction. The present invention relates in particular to a method for the feedback-controlled recirculation of the recovered phosgene, particularly when the phosgene stream that should be recovered is distributed between multiple gas-phase reactors operated in parallel.

Claim (Index 10):
The process of  claim 9 , wherein the proportion of vapor in the two-phase process product produced in step (iv) is kept essentially constant.
