Abstract: A continuous process for producing polyamides, their oligomers or mixtures thereof, if appropriate with further reaction products, comprises reaction of aminonitriles or dinitriles and diamines or mixtures thereof, if appropriate together with further polyamide-forming monomers and/or oligomers, with an aqueous medium composed of aqueous monomer and oligomer extracts obtained from polyamide production by extraction of the polymer with water in a reactor which has a vertical longitudinal axis and through which there is a flow substantially in the longitudinal direction wherein water and/or the aqueous medium are introduced into the reactor at two or more different locations along the vertical longitudinal axis, wherein the aqueous medium is introduced at one or more locations.

Abstract: In a process for distillatively removing ammonia and water from mixtures obtained in the preparation of polyamides which comprise a lactam and/or diamines, and, if appropriate, an aminonitrile and/or dinitrile, and also a cyclopentanone impurity in two stages: 1) the mixture is distilled at from 11 to 35 bar to give, as the top product T1, water, ammonia and cyclopentanone, and, as the bottoms B1, water, the lactam and/or diamines, and, if appropriate, the aminonitrile and/or dinitrile, and 2) T1 is distilled at from 11 to 35 bar to give, as the top product T2, ammonia and cyclopentanone, and, as the bottoms B2, water.

Abstract: Polyamides, oligomers thereof or mixtures thereof, if required with further reaction products, are prepared by reacting aminonitriles or dinitriles and diamines or a mixture containing aminonitrile, dinitrile and diamine, and, if required, further polyamide-forming monomers and/oligomers with water in a reactor ( 1 ) having a vertically oriented longitudinal axis, by a process in which, in the reactor ( 1 ), the reaction product is removed from the bottom and ammonia formed and any further low molecular weight compounds formed and water are taken off via the top ( 2 ), wherein the reactor ( 1 ) has at least two chambers ( 4 ) arranged one on top of the other in the longitudinal direction, the chambers ( 4 ) being separated from one another by liquid-tight trays ( 5 ), each chamber ( 4 ) being connected by a liquid overflow ( 6 ) to the chamber ( 4 ) directly underneath and a liquid product stream being taken off by the liquid overflow ( 6 ) of the lowermost chamber ( 4 ), the gas space ( 7 ) above the liquid level in each chamber ( 4 ) being connected to the chamber ( 4 ) arranged directly above in each case by one or more conduit pipes ( 8 ) which in each case opens or open into a gas distributor ( 9 ) having orifices ( 11 ) for gas exit below the liquid level, and comprising in each case at least one baffle plate ( 12 ) which is arranged vertically around each gas distributor ( 9 ) and whose upper end terminates below the liquid level and whose lower end terminates above the liquid-tight tray ( 5 ) of the chamber ( 4 ) and which separates each chamber ( 4 ) into one or more gassed ( 13 ) and into one or more ungassed ( 14 ) spaces.

Abstract: Disclosed is a method for producing polyamides and the oligomers or mixtures thereof, optionally with additional reaction products, by reacting a reactio n mixture containing monomers that comprise CN groups or -CONH2 groups, other optional polyamide-forming monomers and/or oligomers, and water in a device. 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 t o 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.
