| titleOfInvention | Method for producing polyamides |
| abstract | The present invention relates to a reactor comprising an aminonitrile or dinitrile and diamine, or a mixture comprising aminonitrile, dinitrile and diamine, and optionally further polyamide-forming monomers and / or ) By reacting the oligomers with water to produce polyamides, oligomers thereof or mixtures thereof, optionally with further reaction products. According to this method, the reaction product is discharged from the bottom in reactor 1, and the ammonia formed and all further low molecular weight compounds formed and water are removed through the top (2). The present invention is the reactor (1)n n n One having at least two chambers 4 arranged longitudinally on top of the other,n n n -These chambers 4 are isolated from each other by liquid-tight trays 5,n n n Each chamber 4 is connected to the chamber 4 directly below by a liquid overflow 6, and the liquid product stream is removed by the liquid overflow 6 of the bottom chamber 4,n n n The gas space 7 above the liquid level in each chamber 4 opens at least one gas distributor 9 which in each case has a gas distributor orifice 11 below this liquid level or into such a distributor. By a conduit 8, in each case connected to a chamber 4 arranged directly above it,n n n In each case one or more partition plates 12, which are arranged in a vertical direction around each gas distributor 9, the upper end of which terminates below the liquid level, the lower end of which is connected to the chamber 4. It is terminated on the liquid-tight tray 5 of and characterized by separating each chamber 4 into at least one gas-containing space 13 and at least one gas-free space 14. |
