Abstract

Procedimiento para preparar poliamidas, sus oligómeros o sus mezclas, eventualmente con otros productos de reacción, por reacción de aminonitrilos o dinitrilos y diaminas o una mezcla que contiene aminonitrilo, dinitrilo y diamina, y eventualmente otros monómeros y/u oligómeros formadores de poliamidas con agua en un reactor (1), en donde el reactor (1): representa una cascada de calderas con al menos dos calderas conectadas en seria (4), donde cada caldera (4) está unida por medio de un vertedero de líquidos (6) con la siguiente caldera (4) y se extrae por el vertedero de líquidos (6) de la última caldera (4) una corriente de producto líquida, se extraen el amoníaco producido a través del espacio de gas (7) por encima del nivel del líquido en cada caldera (4) y eventualmente otros compuestos producidos de bajo peso molecular y agua (2).Process for preparing polyamides, their oligomers or mixtures thereof, possibly with other reaction products, by reaction of aminonitriles or dinitriles and diamines or a mixture containing aminonitrile, dinitrile and diamine, and possibly other polyamide-forming monomers and / or oligomers with water in a reactor (1), where the reactor (1): represents a cascade of boilers with at least two boilers connected in series (4), where each boiler (4) is connected by means of a liquid weir (6) with the next boiler (4) and a stream of liquid product is extracted through the liquid dump (6) of the last boiler (4), the ammonia produced through the gas space (7) above the level of the liquid in each boiler (4) and possibly other compounds produced with low molecular weight and water (2).
