    摘要： 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 aminonitrile, 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 two 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), which 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 chamber (4), thus sub-dividing each chamber (4) into one or more compartments supplied with gas (13) and one or more compartments without gas (14).

    摘要： Disclosed is a continuous method for producing polyamides, the oligomers or mixtures thereof, optionally with other reaction products, by reacting aminonitriles or dinitriles and diamines or mixtures thereof, optionally along with additional polyamide-forming monomers and/or oligomers, with an aqueous medium comprising aqueous monomer extracts or oligomer extracts which are obtained when extracting the polymer with water during the production of polyamides. Said reaction is carried out in a reactor which has a vertical longitudinal axis and is penetrated essentially in the longitudinal direction. According to the inventive method, water and/or the aqueous medium is/are introduced into the reactor at least at two different points located along the vertical longitudinal axis thereof, the aqueous medium being introduced at least at one point.

Said method is characterized in that the surfaces of the device, which enter in contact with the reaction mixture, are entirely or partly made of a material that is selected among a group comprising: a) an austenitic steel containing 15 to 25 percent by weight of chromium, 3 to 35 percent by weight of nickel, 0 to 10 percent by weight of molybdenum, and other optional alloy components, the balance being made up of iron and the percentages by weight being in relation to a); b) a duplex steel containing 20 to 30 percent by weight of chromium, 3 to 10 percent by weight of nickel, 0 to 5 percent by weight of molybdenum, and other optional alloy components, the balance being made up of iron and the percentages by weight being in relation to b); and c) a basic nickel alloy containing 12 to 25 percent by weight of chromium, 12 to 20 percent by weight of molybdenum, and other optional alloy components, the balance being made up of nickel and the percentages being in relation to c). Also disclosed are devices that are used in or intended for such a method.
