  • Patent number: 11226304
    Abstract: An apparatus for selectively detecting an anion in a medium and/or selectively measuring the concentration of an anion in a medium. The apparatus comprises at least one sensor and a conductive polymer film and is configured such that dielectric and/or electric property changes of the conductive polymer film can be detected by the sensor when the conductive polymer film is in hydraulic contact with the medium or after it has been in hydraulic contact with the medium. Methods of selectively detecting an anion in a medium and/or selectively determining a concentration of an anion in a medium are also provided.

  • Patent number: 4414156
    Abstract: The invention relates to a novel process for producing 2-methoxybenzanthrones, starting with 1-aminoanthraquinones, which process is characterized in that, by application of a special reaction medium, namely a dimethylalkanephosphonate, which at the same time acts as a methylation agent in one of the reaction steps, the reaction is performed from beginning to end according to the principle of the single-vessel reaction, that is to say, without isolation of intermediates.The 2-methoxybenzanthrones obtained by this process are important intermediate products for vat dyes.
