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 7):
The process of  claim 4 , wherein the varying of the amount of the vapor introduced into the mixture to be separated in the distillation column comprises:\n a) varying the proportion of vapor in the two-phase process product which is introduced into the distillation column, or b) varying the proportion of vapor in the further stream containing phosgene vapor which is introduced in the distillation column, said further stream containing phosgene vapor being two-phase, or c) by both a) and b).
