Abstract: A process for producing a liquid formulation of salts of sulfonated azo dyes by coupling an at least equimolar amount of diazotized aminoarylsulfonic acids I H2N—Ar—SO3H (I), where Ar is phenylene (which may be monosubstituted by sulfo) or naphthylene (which may be mono- or disubstituted by sulfo and/or monosubstituted by hydroxyl) onto the coupling product of an unsubstituted or methyl-substituted phenylenediamine with itself comprises dissolving the azo dye in a basic medium and then subjecting the solution to a nanofiltration.

Abstract: Fuel cell comprises a cathode, and anode and an electrolyte. The cathode is made from a material of the formula: (Sr1-xCax)1-yAyMn1-zBzO3-d (where A = Ba, Pb, Na, K, Y or lanthanide; B = Mg, Al, Ga, In, Sn or group IVb, Vb or VIb element; x = 0.2-0.8; y = 0-0.4; z = 0 to 1; and d = a value which takes into account the electro-neutrality principle). Preferred Features: The electrolyte is made from tetragonal zirconia polycrystals, scandium doped cubic stabilized zirconium oxide, lanthanum-strontium-gallium-magnesium oxide having a perovskite structure, gadolinium oxide doped cerium oxide, BiCuVOx or BiErOx. The anode is made from metallic or oxide ion conducting materials or a mixed-conducting material having catalytically active components.

Abstract: A method for working up polyether-polyols (I) obtained by ring-opening polymerization of epoxides with hydroxy-functional starters in presence of heterogeneous catalysts involves separating the catalyst from the product (I) by a membrane separation process. An Independent claim is also included for a method for the production of (I) by ring-opening polymerization of epoxides followed by a work-up process using a separation step as above.

Abstract: Preparation of aromatic amines or aliphatic amino alcohols comprises hydrogenating nitro-aromatic compounds or nitro alcohols, respectively in the presence of a catalyst, separating the catalysts from fluid amine- or amino alcohols containing reaction mixture, in a reactor, and measuring the absorption of UV/visible-radiation by the reaction mixture to determine the concentration of nitro and nitroso compounds. An independent claim is included for a device for executing the preparation of aromatic amines or aliphatic amino alcohols.
