摘要： PROBLEM TO BE SOLVED: To provide a production method of aromatic isocyanate by reacting one or more aromatic primary amine with phosgene in the gas phase.
SOLUTION: The phosgene and primary aromatic amine are reacted at a temperature above the boiling temperature of the amine in a reactor having a reaction space which is essentially rotationally symmetric to the direction of flow. The flow rate, averaged over the cross-section, of the reaction mixture along the axis of the essentially rotationally symmetric reaction space in the section of the reaction space in which the conversion of the amine groups into isocyanate groups is 4-80%, is not more than 8 m/s. The flow rate, averaged over the cross-section, of the reaction mixture along the axis of the essentially rotationally symmetric reaction space in the section of the reaction space in which the conversion of the amine groups into isocyanate group is 4-80%, is always below the flow rate averaged over the cross-section at the start of the section.

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.

摘要： PROBLEM TO BE SOLVED: To provide a process for producing an isocyanate by a reaction of corresponding amines with phosgene in the gas phase in which, once the optimum residence time has been reached, the reaction is effectively stopped within a short time and simple separation of the isocyanate from the remaining components of the reaction mixture can be achieved with the result that an isocyanate mixture having a high isocyanate content can further be obtained and the process can be carried out in a simple, compact apparatus with minimal energy input. SOLUTION: The reaction mixture containing the isocyanate is guided from a reaction chamber through a cooling zone in which a liquid is injected to stop the reaction. In the process, the direct cooling is carried out in the cooling zone in one stage in two or more cooling zones connected in series. COPYRIGHT: (C)2008,JPO&INPIT
