  • Publication number: 20100160673
    Abstract: 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.

  • Publication number: 20100160674
    Abstract: Meta-toluene-diisocyanate is produced by reacting meta-toluenediamine with phosgene in the gas phase. The meta-toluenediamine to be vaporized for use in this phosgenation process must contain less than 0.5 wt. % of toluenediamine residue, a total of less than 0.2 wt. % of ammonia and cycloaliphatic amines, and less than 20 ppm of heavy metals. At least 0.1 wt. % of the liquid meta-toluenediamine being to be vaporized must not be vaporized. This non-vaporized content of the meta-toluenediamine must not be fed to the phosgenation reactor.

  • Publication number: 20100152484
    Abstract: 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.

  • Patent number: 7615662
    Abstract: Isocyanates are produced by reaction of primary amines with phosgene in the gas phase. In this process, the reaction is terminated by guiding the reaction mixture from the reaction chamber through a cooling stretch into which liquids are injected. Direct cooling takes place in the cooling stretch in one stage in two or more cooling zones connected in series.

  • Publication number: 20090149672
    Abstract: Aromatic diisocyanates are produced by reacting in the gas phase the corresponding primary aromatic diamine with phosgene. The phosgene and the primary aromatic diamine are reacted within a mean residence time of from 0.05 to 15 seconds. The aromatic diamine used contains less than 0.05 mole % overall of aliphatic amine containing no keto groups, per mole of primary amino groups.
