Abstract

The invention relates to an apparatus and a process for preparing isocyanates by reacting the corresponding amines with phosgene in the liquid phase, wherein either the amine as a first reactant and the phosgene as a second reactant or the phosgene as a first reactant and the amine as a second reactant are mixed in a mixing chamber (1) to form a reaction mixture and the reaction mixture is fed to a reactor, the first reactant being added through a coaxial inlet (3) penetrating a back plane (2) of the mixing chamber (1) and extending coaxially into the mixing chamber (1) with an orifice (4) opening out into the mixing chamber (1) at a distance L1 to the back plane (2), and the second reactant being added through radial orifices (5) opening out into the mixing chamber (1) in at least a first plane (6) arranged perpendicular to the axis (8) of the mixing chamber (1), wherein all radial orifices (5) are arranged upstream of the orifice (4) of the coaxial inlet (3) in the main flow direction of the reaction mixture.
