  • Patent number: 9365503
    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: 20160079536
    Abstract: A radiation-emitting organic-electronic device is specified. The radiation-emitting organic-electronic device includes a substrate, a first electrode arranged above the substrate, a light-emitting layer arranged above the first electrode, and a second electrode arranged above the light-emitting layer. The light-emitting layer includes a fluorescent compound of a specified formula A. The spacer comprises a linear molecular chain to which two substituents R and R? are terminally bonded, and at least one group E bonded to the linear molecular chain, wherein E denotes hydrogen and/or an organic radical. The linear molecular chain of the molecules of the fluorescent compound is aligned parallel to the plane of extent of the substrate.

  • Publication number: 20150333109
    Abstract: An optoelectronic component is provided. The optoelectronic component includes an electromagnetic radiation source including an optically active region designed for emitting a first electromagnetic radiation, and a converter structure, which includes at least one converter material and is arranged in the beam path of the first electromagnetic radiation. The at least one converter material is designed to convert at least one portion of the first electromagnetic radiation into at least one second electromagnetic radiation. The at least one second electromagnetic radiation has at least one different wavelength than the at least one portion of the first electromagnetic radiation. The converter structure is formed in a structured fashion in such a way that the converter structure has a predefined region, such that the at least one second electromagnetic radiation is emittable only from the predefined region. The predefined region has a smaller area than the optically active region.

  • Patent number: 8079752
    Abstract: The invention relates to a mixer reactor of the rotor-stator type. This mixer reactor comprises a substantially rotationally symmetric housing which has a distributing chamber, a mixing chamber, a front plate that modifies the cross-section of the housing between these two chambers, and there are separate inlets into the mixing chamber for at least two substances and an outlet for removing the mixed material or product. The inlet for the first substance is provided in the axis of rotation of the mixing chamber. Two or more channels are aligned radially outward from this inlet, and the first substance is transported through these channels and into the mixing chamber. The inlet for the at least second substance is constructed in the form of a plurality of openings in the front plate, these inlet openings being are arranged rotationally symmetrically to the axis of rotation. Each of these inlet openings for the at least second substance has a corresponding pin which can be displaced in the axial direction.

  • Patent number: 7781624
    Abstract: This invention relates to a process for the continuous preparation of nitrobenzene. This process comprises the adiabatic nitration of benzene with a mixture of sulfuric acid and nitric acid, in which the sum of the concentrations in the reaction zone of the metal ions which form sparingly soluble metal sulfates is less than 900 mg/l, based on the volume of the aqueous phase which contains sulfuric acid.

  • Patent number: 7763759
    Abstract: The invention relates to a continuous process for the manufacture of nitrobenzene. This process comprises the nitration of benzene with nitrating acid that contains at least 3.0 wt. % of nitric acid and at least 67.0 wt. % of sulfuric acid, in a reaction space in which the start temperature of the reaction is above 100.0° C. but below 102.0° C. In addition, this process requires that the benzene and the nitrating acid are dispersed in one another several times.
