Abstract: Esters of 6-aminocaproic acid are prepd. by reacting esters of 5-formyl-valeric acid with NH3 and H2, with alcohols as solvents, in presence of hydrogenation catalysts under increased pressure and at 40-95 deg. C. Pref. the catalyst is (i) prepd. by calcination of: ((MgaNi(II)bCo(II)cAl2)CO3(OH)16.4H2O at 200-600 deg. C, followed by redn. with H2 at raised temp., or (ii) 30-60 wt.% of finely divided Ni pptd. on Mg silicate. In the formulae, a = 0-4; b, c = 0-6; 2 x (a+b+c) = 12. Pref. alkanol solns. of 5-formyl valeric acid esters are led with NH3 over a fixed bed catalyst. Raney Ni or Raney Co may be used in a suspension process, opt. fixed in the reaction zone (electro)-magnetically. The catalyst is 0.2-2 kg of 5-formylvaleric acid ester/l of catalyst/h. Partic. methyl 5-formylvalerate is used, in soln. in methanol.

Abstract: Prodn. of 3-pentenoate esters (I) is effected by heating 2-pentenoate esters (II) at 50-250 deg. C in the presence of 0.01-0.5 mole of a cyclic tert. amine (III) with a pKa above 6, while continuously distilling off (I).

Abstract: Cyclohexane (I) is produced from mixts. of (I) with benzene and/or cyclohexane by (a) reaction of anthracene (II) (opt. contg. inert substits.) with (I) in the mixt. to form an adduct of (I) and (II), (b) sepg. the addn. prod. from the mixt. and (c) decomposing the addn. prod. to produce (I) and (II) by heating at 150-500 deg.C. Amt. of (II) used is 1-30 mol/mol. (I), stage (a) is carried out at 100-300 deg.C and 10-300 bar, (II) is substd. with up to two 1-4C alkyl gps., temp. in stage (c) is 200-400 deg.C. Typical mixts. contain 10-40 wt.% (I), 1-50 wt.% cyclohexane and 10-90 wt.% benzene, suitable substd. (II) are e.g. 2- or 9-methyl-(II), 9-ethyl-(II), 9-chloro-(II), 9-cyano-(II) etc., adduct is sepd. by crystallisation and filtration or by distillation of benzene and cyclohexane and decomposed at 200-400 deg.C and 0.1-10 bars.

Abstract: Caprolactam is prepared by heating a 6-aminocaproic ester in liquid phase in the presence of water to 230 DEG -350 DEG C. under superatmospheric pressure in a reaction medium comprising a liquid aromatic hydrocarbon having a boiling point of from 80 DEG to 240 DEG C. which is inert under reaction conditions, and isolating caprolactam from the reaction mixture.
