Abstract
PROCEDIMIENTO PARA LA OBTENCION DE POLIAMIDAS, QUE TIENEN APLICACIONES PARA LA FABRICACION DE HILOS. CONSISTE EN LA REACCION DE UN DINITRILO, TAL COMO ADIPONITRILO, UNA DIAMINA ALIFATICA TAL COMO HEXAMETILENDIAMINA Y UN EXCESO DE AGUA, EN PRESENCIA DE UN CATALIZADOR QUE PUEDE SER UN COMPUESTO DE FOSFORO OXIGENADO, UN COMPUESTO DE BORO OXIGENADO, UN COMPUESTO DE AZUFRE OXIGENADO, Y UN HALURO DE HIDROGENO O SUS SALES AMONICAS Y DE ALCOHILAMONIO. LA REACCION SE LLEVA A CABO EN CASCADA A UNA TEMPERATURA SUPERIOR A 150 C Y A UNA PRESION SUPERIOR A LA ATMOSFERICA.
