    Abstract: PROBLEM TO BE SOLVED: To provide a process for the continuous hydrogenation of a nitrile to a primary amine, by which the mild hydrogenation of the nitrile can simply be carried out and especially by which the formation of the primary amine in high selectivity and the avoidance of a secondary treatment such as the separation of the nitrile can be achieved. SOLUTION: In this process for the continuous hydrogenation of the nitrile to the primary amine in a liquid phase over a suspended, activated Raney catalyst based on an alloy of aluminum and at least one transition metal selected from the group consisting of iron, cobalt and nickel, and, if desired, one or more further transition metals selected from the group consisting of titanium, zirconium, chromium and manganese, the hydrogenation is carried out in the absence of ammonia and basic alkali metal compounds or alkaline earth metal compounds.

    Abstract: The invention relates to a method for producing 2-keto-L-gulonic acid-C4-C10 alkyl ester by esterifying 2-keto-L-gulonic acid (KGS) with an unsaturated, branched or unbranched C4-C10 alcohol. The inventive method is characterized by the fact that an aqueous KGS solution is reacted with a C4-C10 alcohol up to an esterification degree of 20 to 70 percent in a pre-esterification process carried out under acidic catalysis conditions; and the obtained product is dehydrogenated with an unsaturated, branched or unbranched C4-C10 alcohol in a continuous rectification device, whereby the esterification reaction continues, n-butanol preferably being used as the alkyl alcohol. In a preferred embodiment, the aqueous KGS solution is concentrated up to or beyond the limit of solubility prior to the esterification process, preferably by catalyzing a homogeneous or heterogeneous catalyst, especially sulfonic acid, at temperatures of 50 to 120 °C. In another embodiment, the produced KGS ester is reacted in one or several additional steps so as to obtain L-ascorbic acid.
