  • Patent number: 6043370
    Abstract: A method for the production of arylamine is described, which comprises allowing an aromatic amine to react with an aromatic halide in the presence of a copper-containing catalyst in a reaction solvent having an ionization potential of from 8.0 to 9.0 eV. According to the method of this invention, an arylamine, in particular a triarylamine or diarylamine, useful as a raw material for use in electronic materials or as an intermediate thereof can be produced with a high purity and in a high yield or at a low cost.

  • Patent number: 5710012
    Abstract: Water soluble salts of hydrazone compounds react quickly with aniline compounds in the presence of a peroxidase and hydrogen peroxide to provide a color which can be measured spectrophotometrically or visually, either in solution or when incorporated in a device for the measurement of analytes of interest. These water-soluble hydrazone salts are useful in determining hydrogen peroxide or an analyte which reacts to produce hydrogen peroxide in an aqueous liquid, by, in the presence of a substance having peroxidative activity, physically contacting a sample of a liquid with a dye-forming composition comprising a water-soluble salt of a hydrazone compound and a substituted or unsubstituted aniline compound to produce a colored dye; and detecting the dye formed as a result of the presence of hydrogen peroxide or an analyte which reacts to produce hydrogen peroxide.
