    Abstract: The invention relates to a method for producing adipodinitrile and methylglutar nitrile, said method being characterised by the following steps : (a) an educt flow containing pentenenitriles is reacted with hydrogen cyanid e in the presence of at least one catalyst and at least one promoter to obtain a reaction flow containing pentenenitriles, the at least one catalyst, catalys t breakdown products, the at least one promoter, adipodinitrile and methylglut ar nitrile; (b) the reaction flow is distilled to obtain a bottom product flow (3) that is depleted of pentenenitriles and contains the at least one catalyst, catalyst breakdown products, the at least one promoter, adipodinitrile and methylglutar nitrile, and a top product flow (4) enriched in pentenenitriles; (c) the flow (3) is extracted by an extraction means contained in flow (5) to obtain a top product flow (6) that is enriched with extraction means and contains the catalyst, and a bottom product flow (7) th at is depleted of extraction means and contains catalyst breakdown products, th e at least one promoter, pentenenitriles, adipodinitrile and methylglutar nitrile; (d) the flow (6) is distilled to obtain a bottom product flow (8) containing the catalyst, and a top product flow (9) containing the extractio n means; (e) the flow (7) is distilled to obtain a bottom product flow (10) containing catalyst breakdown products, the at least one promoter, pentene nitriles, adipodinitrile and methylglutarnitrile, and a top product flow (11 ) containing the extraction means; (f) the flow (10) is distilled to obtain a bottom product flow (12) containing catalyst breakdown products, the at leas t one promoter, pentenenitriles, adipodinitrile and methylglutarnitrile, and a top product flow (13) containing pentenenitriles; (g) the flow (12) is distilled to obtain a bottom product flow (14) containing catalyst breakdown products and the at least one promoter, and a top product flow (15) containi ng adipodinitrile and methylglutar nitrile; and (h) the flow (15) is distilled to obtain a bottom product flow (16) containing adipodinitrile, and a top produ ct flow (17) containing methylglutarnitrile.

    Abstract: The invention relates to a method for separating a mixture containing a) a monoethylenically unsaturated compound that can be obtained by adding two terminal olefins carrying the functional groups necessary for producing the monoethylenically unsaturated compound containing at least two functional groups, or a saturated compound obtained by hydrogenating one such compound, b) a compound that can be obtained by adding more than two of the terminal olefins cited in a) or a compound obtained by hydrating one such compound, a nd c) a compound which contains a transition metal, is homogeneous in relation to the mixture, and is suitable as a catalyst for producing a monoethylenically unsaturated compound by adding two terminal olefins carrying the functional groups necessary for producing the monoethylenically unsaturated compound containing at least two functional groups. According to said method, the mixture is separated by means of a semi-permeable membrane, obtaining a permeate and a retentate, in such a way that the weight ratio of constituent b) to constituent c) in the mixture supplied to the semi-permeable membrane is smaller than in the retentate.

    Abstract: A process for hydrogenating a monoolefinically unsaturated compound which bears at least two functional groups which are each independently selected from the group consisting of nitrile group, carboxylic acid group, carboxylic ester group, carboxamide group to a saturated compound which bears the same at least two functional groups, in the presence of a rhodium-containing compound, as a catalyst, which is homogeneous with respect to the reaction mixture.
