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: The invention relates to a method for producing 1,2-dodeca-2,10-diene diacid and 1,12-dodecanoic acid whereby cyclooctene and acrylic acid are reacted with a ruthenium catalyst by way of a metathesis reaction at high substrate concentrations until the reaction takes place in substance, the resulting unsaturated dicarboxylic acid being precipitated and being hydrated in a second reaction step.

Abstract: Continuous and/or discontinuous process for the preparation of the cyclododecatriene comprises conversion of butadiene to a raw cyclododecatriene, in the presence of solvent, at least a catalyst system containing nickel and/or titanium and at least an organometal compound, and adding a compound containing at least an element of V group to the catalyst system, where: the solvent before the addition of the catalyst component contains 10-1000 pm of a polar component (I). Continuous and/or discontinuous process for the preparation of the cyclododecatriene comprises conversion of butadiene to a raw cyclododecatriene, in the presence of solvent, at least a catalyst system containing nickel and/or titanium and at least an organometal compound, and adding a compound containing at least an element of V group to the catalyst system, where: the solvent before the addition of the catalyst component contains 10-1000 pm of a polar component (I) of formula (HO-R) and the reaction temperature for the catalyst containing nickel is up to 140[deg]C and for catalyst containing titanium is maximum of 80[deg]C. R : 1-18C-(cyclo)alkyl, 1-18C-aryl, 1-18C-aralkyl or H. An independent claim is included for a material mixture, obtained by the above method, comprising cyclododecatriene, where the ratio of the cyclododecatriene to higher oligomer is at least 10:1, preferably greater than 20:1.
