Abstract

LA PRESENTE INVENCION DESCRIBE UN PROCEDIMIENTO EFICIENTE PARA LA RECUPERACION DE CAPROLACTAMA A PARTIR DE MATERIAL RESIDUAL QUE CONTIENE POLICAPROLACTAMA. EL PRESENTE PROCEDIMIENTO PARA DESPOLIMERIZAR MATERIAL RESIDUAL DE VARIOS COMPONENTES QUE COMPRENDE COMPONENTES DE POLICAPROLACTAMA Y DE NO POLICAPROLACTAMA PARA FORMAR CAPROLACTAMA; CONSTA DE LA SIGUIENTE ETAPA: EN AUSENCIA DE CATALIZADOR SE PONE EN CONTACTO EL MATERIAL RESIDUAL DE VARIOS COMPONENTES CON VAPOR SOBRECALENTADO A UNA TEMPERATURA DE UNOS 250 (GRADOS) C HASTA UNOS 400 (GRADOS) C Y A UNA PRESION DENTRO DEL RANGO DE APROXIMADAMENTE 1 ATM HASTA UNAS 100 ATM Y CLARAMENTE MENOR QUE LA PRESION DE SATURACION DEL AGUA, A LA TEMPERATURA DONDE SE FORMA UNA CORRIENTE DE VAPOR QUE CONTIENE CAPROLACTAMA. LA CAPROLACTAMA FORMADA SE PUEDE UTILIZAR ENTONCES EN LA PRODUCCION DE RESINAS Y FIBRAS TECNICAS.
