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.
该发明涉及一种通过在气相中将相应的一次胺与
光气反应来生产
异氰酸酯的方法,其中
光气通过外环通道注入到气态胺流中,在流管的内部,并通过几个与气态胺流的流动方向成≦90°角度的径向通道注入,其中在流管的内部同轴设置了KENICS类型的静态混合器。
