    Abstract: A process for catalytic hydrogenation of adiponitrile to hexamethylenediamine at elevated temperature and elevated pressure in the presence of catalysts based on elemental iron as catalytically active component and ammonia as solvent comprisesa) hydrogenating adiponitrile at from 70 to 220° C. and from 100 to 400 bar in the presence of catalysts based on elemental iron as catalytically active component and ammonia as solvent to obtain a mixture comprising adiponitrile,6-aminocapronitrile, hexamethylenediamine and high boilers until the sum total of the 6-aminocapronitrile concentration and the adiponitrile concentration is within the range from 1 to 50% by weight, based on the ammonia-free hydrogenation mixture,b) removing ammonia from the hydrogenation effluent,c) removing hexamethylenediamine from the remaining mixture,d) separating 6-aminocapronitrile and adiponitrile from high boilers individually or together, ande) returning 6-aminocapronitrile, adiponitrile or mixtures thereof into step a).

    Abstract: The present invention relates to the manufacture of solid materials or shape d bodies containing at least one zeolite and being at least partly crystalline . Furthermore, the present invention relates to the solid materials or shaped bodies as such and to the use of these materials for reactions of compounds having at least one C-C double bond with at least one hydroperoxide. Specifically, the present invention relates to a process for the manufacture of a solid material containing at least one zeolite and being at least partl y crystalline, wherein the synthesis of the said solid material involves at least one partial step of contacting at least one transition metal oxide source with at least one epoxide or hydrolysate thereof prior to or during t he at least partial crystallization of said solid material.

    Abstract: The invention concerns the simultaneous preparation of caprolactam and hexamethylene diamine from adipodinitrile, by the following steps: (a) the adipodinitrile is partially hydrogenated, producing a mixture substantially containing 6-aminocapronitrile, hexamethylene diamine, ammonia, adipodinitrile and hexamethylene imine (= "the mixture"); (b) the mixture obtained in step (a) is distilled, producing ammonia, as the forerunnings, and a residue I, in the presence of a compound A which is inert in the distillation conditions, the ammonia not being separated totally; (c) the residue I, substantially containing "the mixture", inert compound A and ammonia, the ammonia content being less than that of the mixture used in step (b), is subjected to a second distillation, producing a mixture of the inert compound A and ammonia, as the forerunnings, and a residue II; (d) the base II, substantially containing "the mixture" and inert compound A, is subjected to distillation in a third column, producing the inert compound A, as the forerunnings, and a residue III; (e) the base III, substantially containing "the mixture" and optionally an inert compound B, is subjected to distillation in a fourth column, producing forerunnings KP1, which substantially contain hexamethylene imine, optionally inert compound B and hexamethylene diamine, and a residue IV; (f) the forerunnings KP1 are subjected in a fifth column to distillation, producing forerunnings KP2, which substantially contain hexamethylene imine and optionally inert compound B, and a residue V, which substantially contains hexamethylene diamine with a degree of purity of at least 95 %, the forerunnings KP2 being fed to the third column or optionally only partially fed to the third column, and the rest being discarded; and (g) the residue IV, substantially containing 6-aminocapronitrile and adipodinitrile, is subjected in a sixth column to distillation, producing 6-aminocapronitrile with a degree of purity of at least 95 %, as forerunnings, and adiponitrile in the residue. The resultant 6-aminocapronitrile is cyclized to form caprolactam.

    Abstract: The invention relates to a method for producing oxirans by reacting an organ ic compound with a hydroperoxide in the presence of a solvent and a catalyst. Said method comprises at least the steps (i) to (iii): (i) reaction of the hydroperoxide with the organic compound to obtain a product mixture containi ng the reacted organic compound and non-reacted hydroperoxide, (ii) isolation o f the non-reacted hydroperoxide from the mixture resulting from stage (i), (ii i) reaction of the isolated hydroperoxide from stage (ii) with the organic compound. The method is characterised in that the reaction in step (iii) tak es place in a tubular reactor, which comprises at least two feed points for the reaction mixture, the latter containing at least the organic compound, the hydroperoxide and the solvent, or at least two outlet points for the product mixture, or at least two feed points and at least two outlet points.
