Abstract:
The invention relates to a method for an economically and technically improved embodiment of a production interruption in a production method for isocyanates by phosgenation of the corresponding amines, in which the entire production plant is not closed while one or more parts of the plant is taken out of operation, rather the input materials and/or reaction products available in the production plant are recirculated through at least one part of the plant that has not been taken out of operation. The invention further relates to a plant for producing isocyanates and to a method for operating a plant for producing isocyanates.

Claim (Index 5):
The process as claimed in  claim 1 , in which the liquid output stream from the reaction space or, if present, from the separation unit in step I) is used as input stream for the distillation apparatus in step II), wherein the liquid output stream from the distillation apparatus in step II) is used as input stream for the distillation apparatus in step III), wherein the gaseous output stream from the distillation apparatus in step III), optionally after condensation in a condenser, is used as input stream for the distillation apparatus in step IV), wherein the liquid output stream from the distillation apparatus in step IV) is conducted via the units for providing solvent, for providing an amine and for mixing into the reaction space and thence, if present, into the separation unit in step I).
