  • METHOD FOR PRODUCING ISOCYANATES IN THE GAS PHASE
    Publication number: 20170305842
    Abstract: 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 the 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.
