摘要： The present invention provides a process for quenching a gaseous reaction mixture during the phosgenation of diamines in the gas phase to produce diisocyanates. The gaseous reaction mixture contains at least a diisocyanate, phosgene and hydrogen chloride. The quenching liquid is injected into the gas mixture continuously flowing out of a cylindrical reaction zone into the downstream cylindrical quenching zone with the aid of at least two spray nozzles which are arranged at the entrance to the quenching zone at equal distances along the circumference of the quenching zone.

摘要： The present invention is directed to a process for the isothermal nitration of aromatic organic compounds, wherein an aromatic organic compound is brought into contact and reacted with a mixture of sulfuric acid and nitric acid. The mixture of sulfuric acid and nitric acid, and the aromatic organic compound are brought into contact with each other through a mixing nozzle which comprises a substantially cylindrical tubular reactor and an annular gap which surrounds the tubular reactor. The aromatic organic compound flows through the tubular reactor, and the mixture of sulfuric acid and nitric acid flows through the annular gap, and they are mixed together upon emerging from the tubular reactor and the annular gap, wherein the ratio of the average rates of flow of the aromatic organic compound in the tubular reactor, and of the mixture of sulphuric acid and nitric acid in the annular gap ranges from 0.5:1 to 10:1.

摘要： Aromatic isocyanates are produced by reacting one or more aromatic primary amines with phosgene in the gas phase. The phosgene and primary aromatic amine(s) are reacted at a temperature above the boiling temperature of the amine(s) in a reactor having a reaction space which is essentially rotationally symmetric to the direction of flow. The flow fate, 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 between 4 and 80% is not more than 8 m/sec. 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 to 80% is always below the flow rate averaged over the cross-section at the start of this section.

摘要： A process for preparing isocyanates in the gas phase, in which the mixing of the reactants and thus the reaction conditions are significantly improved by means of hydrodynamic measures such as increasing the turbulence of the feed stream in the central nozzle. As a consequence, the necessary residence time in the reactor and thus the length of the reactor are reduced and the formation of polymeric by-products which lead to caking in the reactor and a shortening of the operating period of the reactors is avoided.

摘要： Primary isocyanates are produced by reacting the corresponding primary amine(s) with phosgene at a temperature above the boiling temperature of the amine(s) in a tube reactor with a reaction space. In this tube reactor, at least one educt stream P containing phosgene and at least one educt stream A containing the amine(s) are fed to the reaction space via a nozzle arrangement. The nozzle arrangement includes a number of n≧1 nozzles aligned parallel to the axis of rotation of the tube reactor and a free space surrounding the nozzles. One of the educt streams A or P is fed to the reaction space via the nozzles and the other educt stream is fed to the reaction space via the free space surrounding the nozzles. The reaction space contains at least one moving mixing device.
