Abstract: The invention relates to a method for producing aliphatic alpha-omega amino nitriles in the presence of a catalyst composed of (a) iron or an iron based compound or a mixture thereof (b) 0.01 to 5 wt. %, in relation to (a), a promoter based on 2, 3, 4, or 5 elements selected from the group comprising aluminum, silicon, zirconium, titanium, and vanadium, and (C) to 0.5 wt. % in relation to (a) a compound based on an alkaline metal or alkaline-earth metal. The inventive method is characterized in that the aliphatic alpha-omega dinitrile contains 1.0 ppm or more phosphorus. Catalysts are obtainable through the reductive and optional successive passivation of magnetite, whereby the catalysts have a BET surface of 3 to 10 m2/g, a total pore volume of 0.05 to 0.2 ml/g, an average pore diameter of 0.03 to 0.1 mm and a pore volume portion in the range of 0.01 to 0.1 mm of 50 to 70%.

Abstract: The invention relates to a method for the separation of ascorbic acid from a mixture containing ascorbic acid and 2-keto-L-gulonic acid in a polar, preferably aqueous solvent, by means of liquid/liquid extraction using an amide. The method preferably also comprises steps for the back-extraction of the ascorbic acid, recycling of the extraction solvent and/or the back extraction solvent and for isolation of the ascorbic acid from the back extraction solvent. The invention further relates to a method for the production of ascorbic acid from KGA and isolation of the ascorbic acid so produced.

Abstract: 2-Keto-L-gulonic acid (KGA) is extracted from a polar solvent, by contacting the solvent with an extractant (E1) comprising a tertiary amine (I) and a polar organic diluent (II) in a mixing region. 2-Keto-L-gulonic acid (KGA) is extracted from a (preferably aqueous) polar solvent, by contacting the solvent with a first extractant (E1) comprising a tertiary amine of formula NR1R2R3 (I) and a polar organic diluent (II) in a mixing region. R1 - R3 = 6-14C (preferably 8-12C) alkyl. An Independent claim is also included for the production of ascorbic acid (AA), by at least partially lactonizing KGA, extracting KGA from the obtained AA/KGA mixture by the above method and isolating AA from the residual solution.
