    Abstract: (i) 5-formyl-valeric acid ester is reacted with excess NH3 and H2 in alkanols as solvents, in the presence of hydrogenation catalysts, under increased pressure, at 40-130 deg.C. (ii) NH3 and H2 are removed from the reaction mixt. obtd. (iii) The reaction mixt. is reacted with water, with heating, esp. at 80-150 deg. C, with the simultaneous sepn. of the alkanols. (iv) The reaction mixt. obtd. is heated to 150-370 deg.C and epsilon-caprolactam is recovered. (A) Prefd. catalysts are prepd. by calcining cpds. having formula (I): ((MgaNi(II)bCo(II)c)Al2)CO3(OH)16x 4 H2O (I) a = integer or decimal no. 0-4; b,c = integer or decimal nos. 0-6; provided that 2 x (a + b + c) = 12, at 200-600 deg.C, and subsequent redn. with H2 at higher temp., e.g. 350-400 deg.C (B) Ni catalysts can also be used contg. 30-60 wt.% finely-divided Ni pptd. on Mg silicate. (C) Raney-Ni or Raney-Co can be used as catalyst for working in a suspension process. (D) The Raney-Ni or Raney-Co catalyst can be fixed magnetically or electro-magnetically in the reaction zone.

    Abstract: A process for the preparation of a 2,2-disubstituted pentane-1,5-diamine of the formula I (see formula I) where R1 and R2, independently of one another, are C1- to C10-alkyl or C2- to C10-alkenyl or together are a C4- to C7- alkylene chain which is unsubstituted or monosubstituted to pentasubstituted by C1- to C4-alkyl, from a 2,2-di- substituted 4-cyanobutanal of the formula II (see formula II) where R1 and R2 are as defined above, comprises, in two spatially separate reaction spaces, a) reacting the 4-cyanobutanal of the formula II, in a first reaction space, with excess ammonia on an acidic heterogeneous catalyst at from 20 to 150.degree.C and at from 15 to 500 bar, and b) hydrogenating the resultant reaction product, in a second reaction space, using excess hydrogen in the presence of excess ammonia on a catalyst containing cobalt, nickel, ruthenium and/or another noble metal, if desired with a basic component or on a basic or neutral carrier, at from 60 to 150.degree.C and at from 50 to 500 bar. 2,2-Disubstituted pentane- 1,5-diamines of the formula I' (see formula III) where R1' and R2', independently of one another, are C1- to C10-alkyl or C2- to C10-alkenyl or together are a C4- to C7-alkylene chain which is unsubstituted or monosubstituted to pentasubstituted by C1-to C4-alkyl, with the proviso that R1' and R2' are not simultaneously methyl are also described.

    Abstract: PROCEDIMIENTO PARA LA OBTENCION DE CAPROLACTAMA POR CALENTAMIENTO DE ESTERES 6-AMINOCAPROICOS EN PRESENCIA DE UN MEDIO ORGANICO INERTE, LIQUIDO EN LAS CONDICIONES DE LA REACCION, CON UN PUNTO DE EBULLICION INFERIOR AL DE LA CAPROLACTAMA. EL PROCEDIMIENTO SE CARACTERIZA PORQUE SE EMPLEAN COMO MEDIO DE REACCION HIDROCARBUROS AROMATICOS CON UN PUNTO DE EBULLICION DE 80 A 240 GRADOS C, SE MANTIENE UNA TEMPERATURA ENTRE 100 Y 320 GRADOS C, Y SE OBTIENE CAPROLACTAMA A PARTIR DEL MEDIO DE REACCION.
