Abstract: By the method oxidation products of cyclohexane are produced by catalytic oxidation with oxygen-containing gas in liquid phase where the gases enter at least one reaction zone, essentially evently, in contact with liquid cyclohexane. The liquid cyclohexane and the oxygen-containing gases are introduced in a counterflow across the reaction zone. 10 claims

Abstract: The invention concerns a process for preparing oxidation products from cyclohexane by catalytic oxidation with oxygenous gases in the liquid phase. In a reaction zone the gases are brought substantially uniformly into contact with the oxygenous gases, and liquid cyclohexane and the oxygenous gases are passed in counterflow through the reaction zone.

Abstract: The invention relates to a method for producing polyamides, their oligomers or mixtures thereof, optionally containing other reaction products, by reacting aminonitriles or dinitriles and diamines or a mixture containing aminonitril e, dinitrile and diamine and optionally additional polyamide-forming monomers and/or oligomers with water in a reactor (1) with a vertical longitudinal axis. According to said method, the reaction product is exfiltrated from the sump in the reactor (1) and accumulated ammonia and optionally other accumulated low-molecular compounds and water are drawn off via the head (2) . The invention is characterised in that the reactor (1) comprises at least tw o chambers (4) arranged in a longitudinal direction one above the other, that the chambers (4) are separated from one another by liquid-tight floors (5), that each chamber (4) is connected to the one (4) immediately below by a respective liquid overflow (6) and a liquid product stream is drawn off via the liquid overflow (6) of the lowest chamber (4), that the gas chamber (7) above the liquid level in each chamber (4) is connected to the respective chamber (4) lying immediately above it via one or several conduits (8), whic h open respectively into a gas diffuser (9) comprising orifices (11) for the discharge of gas below the liquid level. The reactor also comprises at least one respective deflector plate (12) positioned vertically around each gas diffuser (9), the upper end of said plate terminating below the liquid level and the lower end terminating above the liquid-tight floor (5) of the chambe r (4), thus sub-dividing each chamber (4) into one or more compartments suppli ed with gas (13) and one or more compartments without gas (14).
