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: Preparation of lactams by gas phase cyclizing hydrolysis of aminonitriles is carried out in the presence of a metal phosphate catalyst comprising oligophosphate(s) (I) of group 3 and/or 4 metal(s), including lanthanide(s), and optionally their salt(s) (II) with an inorganic acid. Preparation of lactams by gas phase cyclizing hydrolysis of aminonitriles is carried out in the presence of a metal phosphate catalyst comprising oligophosphate(s) of formula M(POa)b (I) of group 3 and/or 4 metal(s), including lanthanide(s), and optionally their salt(s) (II) with an inorganic acid; M = a group 3 or 4 metal, including lanthanides; a = 2.5-4.0; b = a value giving a neutral charge. Independent claims are also included for (a) the preparation of the catalyst; and (b) the use of (I) and optionally (II) as catalysts in this process, especially in caprolactam production.

Abstract: ALIPHATIC ALPHA, OMEGA-AMINONITRILES ARE PREPARED IN THE PRESENCE OF A CATALYST WHICH CONTAINS(A)IRON OR A COMPOUND BASED ON IRON OR A MIXTURE THEREOF, (B)FROM 0.01 TO 5BY WEIGHT, BASED ON (a), OF A PROMOTER BASED ON 2, 3, 4, AND 5 ELEMENTS SELECTED FROM A GROUP CONSISTING OF ALUMINUM, SILICON, ZIRCONIUM, TITANIUM AND VANADIUM AND (C)FROM 0 TO 0.5BY WEIGHT, BASED ON(a), OF A COMPOUND BASED ON AN ALKALI METAL OR ALKALINE EARTH METAL, BY A PROCESS IN WHICH THE ALIPHATIC ALPHA, OMEGA-DINITRILE USED CONTAINS 2.0 PPM BY WEIGHT OF MORE OF PHOSPHORUS. CATALYSTS ARE OBTAINABLE BY THE REDUCTION AND, IF REQUIRED, SUBSEQUENT PASSIVATION OF A MAGNETITE, THE CATALYSTS HAVING A BET SURFACE AREA OF FROM 3 TO 10 M2/G, WITH A TOTAL PORE VOLUME OF FROM 0.05 TO 0.2 M1/G, AN AVERAGE PORE DIAMETER OF FROM 0.03 TO 0.1 µM AND A PORE VOLUME FRACTION OF FROM 50 TO 70IN THE RANGE OF FROM 0.01 TO 0.1 µM.
