SOLUTION: There is provided the method wherein a primary amine and phosgene are reacted in a gas phase, in a tubular reactor at a temperature above the boiling point of the amine, the reactant stream is flown in the reaction space via a nozzle arrangement, thereby, one reactant stream is fed to the reaction space via n≥1 nozzles alined parallel to the axis of the reaction space, and a second reactant stream is supplied to the reaction space via a free space surrounding the nozzles. Thereby, after the test time of 200 h, the pressure difference between the pressure in a TDA supply pipe line and the pressure at the gas outlet from the condensing step is 11 mbar and has not changed within a range of the measuring accuracy of the large scale industrial measuring device. The inspection has not indicated the presence of solid sediment.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing a solvent-free isocyanate by providing a possibility of reducing the quantity of the solvent required in the flow of dephosgenated isocyanate, in this case, the isocyanate flow must be separated in the post-treatment, that is, by higher phosgene concentration in the solvent totally carried out in the circulating route. SOLUTION: An appropriate amine is reacted with phosgene, condensing the gas mixture thereby obtained, stripping the liquid phase thereby obtained, the solvent so retained in liquid form is returned to the reaction stage of amine and phosgene, and in the case of selectable method, the total quantity of the solvent in the circulating route is constant and the quantity of the solvent for the refining of hydrogen chloride can be increased, in case a further treatment appropriately selected is thus required.

摘要： PROBLEM TO BE SOLVED: To provide a vapor-phase isocyanate production method which is commercially advantageous. SOLUTION: The production of an isocyanate by reacting a suitable primary amine with phosgene in a vapor phase is practiced under adiabatic conditions by ensuring that the average residence time in a reaction chamber is 0.05-15 sec. Thus, desirably, it is possible to avoid a problem of temperature control irrespectively of the shape of a reactor, to produce an isocyanate in a high space-time yield on an industrial scale, and to accomplish a substantial increase in the length of the operation time of a production plant.
