Abstract: The invention relates to a multi-stage method for the continuous production of organic, distillable polyisocyanates, preferably diisocyanates, especially preferably aliphatic or cycloaliphatic diisocyanates, by reacting the corresponding organic polyamines with carbonic acid derivatives and alcohol in low-molecular monomer polyurethanes and to the thermal splitting of the latter. During said method, the polyisocyanates produced and unusable residues are separated at specific reaction stages and reusable secondary and intermediate products are recirculated to the initial stages.

Abstract: The invention relates to a method for producing isocyanates by converting the corresponding amine with phosgene in the gas phase, in the presence of an inert medium as applicable, wherein phosgene and amine are first vaporized and then overheated to reaction temperature, the overheated phosgene and amine are mixed and added to a reactor wherein the phosgene and the amine are converted to isocyanate, wherein the dwell time of the phosgene at temperatures greater than 300°C equals a maximum of 5 sec and/or the temperature of heat transfer surfaces in contact with the phosgene is 20 K above the phosgene temperature to be set at maximum. The invention further relates to a device for producing isocyanates by converting the corresponding amine with phosgene in the gas phase.
