Abstract: The invention relates to a whole-cell catalyst which expresses a recombinant a-dioxygenase or a combination of a recombinant fatty acid reductase and a phosphopanthetheinyl transferase which phosphopanthetheinylates the fatty acid reductase, and which, in addition to the a-dioxygenase and/or the combination of fatty acid reductase and phosphopanthetheinyl transferase, expresses a transaminase, where the phosphopanthetheinyl transferase and/or transaminase is preferably recombinant. The invention also relates to a method for converting a carboxylic acid or dicarboxylic acid or a monoester thereof into an amine or diamine, comprising the steps of contacting the carboxylic acid or dicarboxylic acid or the monoester thereof with a phosphopanthetheinylated fatty acid reductase or an a-dioxygenase and contacting the product with a transaminase.

Abstract: Die Erfindung betrifft die katalytische Umwandlung von in ihrer Hauptkette linearen Diolen mit Kohlenstoffzahlen von C4 bis C31 zu den korrespondierenden Diaminen. Die Reaktion erfolgt in flüssiger oder überkritischer Phase mit Ammoniak oder einer Ammoniak freisetzenden Verbindung unter Verwendung homogener Rutheniumhaltiger Komplexe als Katalysatoren. Der Vorteil der Erfindung ist die Erzeugung primärer Diamine in einer solchen Selektivität und Reinheit, dass sie für Polyamidsynthesen geeignet sind.

Abstract: Production of oximes by ammoxidation of a C6-20 carbonyl compound in the presence of a water-miscible organic solvent and a heterogeneous titanium catalyst, separating the catalyst, crystallizing the oxime from the reaction mixture, entraining water from the mother liquor and recycling the solvent. Production of oximes by reacting a carbonyl compound having 6-20 carbon atoms with ammonia and hydrogen peroxide in the presence of a water-miscible organic solvent and a heterogeneous titanium catalyst, separating the catalyst, crystallizing the oxime from the reaction mixture, entraining water from the mother liquor and recycling the solvent comprises using a solvent that boils above 100 degrees C and/or forms an azeotrope with water, distilling water or azeotrope from the mother liquor and recycling the distillation bottoms and optionally the organic phase of the azeotrope.

Abstract: The invention relates to a plant for carrying out chemical reactions, having a reactor (1), the reaction space of which contains hydrogen peroxide (H2O2) and titanium silicalite (TS-1). The object of the invention is to improve such a plant such that continuous separation and recycling of the active catalyst to the reaction space is possible with a long filter service life. This is achieved in that the reaction space contains a solid silicon source, in that the plant comprises a water takeoff line (3) which is set up for drawing off water in addition to components which are dissolved and/or dispersed therein from the reaction space, in that the water takeoff line (3) leads to a filter (4) which separates off the components which are dissolved and/or dispersed in the water, and in that the plant has a return line (5) which is set up for recirculating to the reaction space components which are separated off by means of the filter (4).

Abstract: The present invention describes the preparation of cyclododecatriene in a continuous or discontinuous process by trimerization of butadiene in the presence of a catalyst system and a solvent, the crude cyclododecatriene obtained being able to be isolated by means of distillation. The cyclooctadiene formed as by-product can likewi se be isolated from the crude product.

Abstract: Degradation acids obtained in the synthesis of carboxylic acids, in particular dicarboxylic acids, having from 8 to 16 carbon atoms may be isolated by separating the degradation acids in the form of a solid from the crude reaction mixture, then washing the degradation acids in the form of an oil with water at an elevated temperature. The resulting degradation acids having low oxidant and metal contents, and the metal catalyst may be recirculated back to the process.
