Abstract: Mixtures containing cyclohexyl hydroperoxide, cyclohexanol and cyclohexanone and having a high cyclohexyl hydroperoxide content are prepared by a continuous process which comprises the oxidation of cyclohexane with molecular oxygen, or with a gas containing this, in the liquid phase, in which 1. in a first stage, molecular oxygen is dissolved in cyclohexane by bringing the latter into contact with molecular oxygen, or with a gas containing this, at from 10 to 110.degree.C and under superatmospheric pressure, and 2. in a second stage, the cyclohexane containing dis solved molecular oxygen is passed through an elongated, tubular reaction zone at from 130 to 250.degree.C and under superatmospheric pressure, virtually with plug flow and without the formation of a gas phase, the residence time being between a) the time required for the consumption of 50% of the amount of dissolved molecular oxygen and b) 1.2 times the time required for the consumption of 99.9% of the dissolved molecular oxygen.

Abstract: Solutions of molecular oxygen in liquid hydrocarbons are prepared by bringing a liquid hydrocarbon into contact with molecular oxygen under superatmospheric pressure in a vertical absorption zone, by a process in which (a) a layer of water is maintained at the lower end of the absorption zone, (b) molecular oxygen is passed into the layer of water, (c) a liquid hydrocarbon is fed in above the layer of water, (d) the finely divided molecular oxygen rising from the layer of water is passed upward together with the liquid hydrocarbon at from 0 DEG to 50 DEG C., with thorough mixing in the absorption zone, with the proviso that no cohesive gas phase is formed, and (e) the solution of molecular oxygen in the liquid hydrocarbon is discharged in the upper part of the absorption zone.

Abstract: Hydroxylammonium salts are prepared by an improved process, wherein nitric oxide is reduced catalytically with hydrogen in a dilute aqueous solution of a mineral acid in the presence of a suspended supported platinum catalyst and at elevated temperatures, and wherein the improvement comprises avoiding the formation of foam at the surface of the reaction mixture.

Abstract: Polyamides are moulded by polymerizing lactams in the presence of alkaline catalysts and activators in a mould in which the pressure is sub-atmospheric, preferably 5 to 50 mm.Hg. above the boiling pressure of the lactam to be polymerized. In an example 8 parts of bis-(caprolactam-N-carboxylic acid)-hexamethylene-diamide (1,6) is dissolved in 92 parts of caprolactam at 80 DEG C., and 67 parts of caprolactam is melted with 33 parts of the reaction product of 3 parts of potassium with 97 parts of caprolactam and heated to 80 DEG C. The two melts are then mixed and fed into a mould at 85 DEG C. and a pressure of 10 mm.Hg. Numerous examples of catalysts and activators suitable for the process are given, specified lactams being pyrrolidone, piperidone, caprolactam, enantholactam, caprylolactam, capriclactam, laurolactam, C-methyl-e -caprolactam and dilactams.
