Abstract (en)
[origin: WO2016042124A1] The invention relates to a method for producing isocyanates by reacting the corresponding primary amines with phosgene in the gas phase, wherein the phosgene is injected into the gaseous amine flow in the interior of a flow tube via an outer ring channel and through several radial channels in an angle of ≤ 90° relative to the flow direction of the gaseous amine flow, wherein a static mixer of the Kenics type is provided coaxially in the interior of the flow tube.
