    摘要： The invention provides a process for preparing 4-aminodiphenylamine, an important starting product for synthesizing antioxidants and stabilizers in the rubber and polymer industry, by hydrogenating nitrosobenzene with hydrogen in the presence of a proton acid as catalyst and in the presence of a hydrogenating catalyst, optionally in the presence of an inert organic solvent and thermally decomposing the 4-ADPA ammonium salt produced in this way, wherein 4-ADPA is obtained. 4-aminodiphenylamine is produced in good yields and high purity by the process according to the present invention. Furthermore, no effluent is produced, which makes the process particularly economic and ecological.

    摘要： A variety of diazacyanine mediators that are soluble in aqueous media and which do not inhibit enzymatic activity are provided for use on the surface of a working electrode of a electrochemical biosensor for electrochemical co-enzyme regeneration. The co-enzyme, dihydronicotinamide adenine dinucleotide (NADH) or dihydronicotinamide adenine dinucleotide phosphate (NADPH), is oxidized to NAD.sup.+ OR NADP.sup.+ which is reduced by an oxidoreductase such as a dehydrogenase acting on a substrate. By applying the mediator together with NADH or NADPH to the surface of the working electrode, the voltage necessary to achieve oxidation is substantially reduced. Biosensor electrodes such as graphite electrodes may be produced-by screen printing techniques.
