Abstract

EL COLOR DE RESINAS DE HIDROCARBURO QUE TIENEN ENLACES DOBLES DE CARBONO-CARBONO Y QUE CONTIENEN CUERPOS DE COLOR SE ACLARA MEDIANTE UN PROCESO DE HIDROTRATAMIENTO QUE CONSTA ESENCIALMENTE DE LA PUESTA EN CONTACTO DE UNA RESINA SUSTANCIALMENTE NO CRISTALINA CON HIDROGENO EN UNA PRESION DE HIDROGENO DE 1 A 20 BAR (14,5 A 290 PSI) EN LA PRESENCIA DE UN CATALIZADOR QUE ESTIMULA LA HIDROGENACION DE LOS CUERPOS DE COLORES SIN CAMBIAR SUSTANCIALMENTE EL PUNTO DE SUAVIDAD O EL CONTENIDO DE ENLACES DOBLES DE CARBONO-CARBONO EN LA RESINA. CUANDO EL CATALIZADOR ES OXIDO DE NIQUEL/ZINC, LA ACTIVIDAD DEL CATALIZADOR PARA LA REDUCCION DE COLOR PERMANECE ESENCIALMENTE SIN CAMBIOS EN CARGAS DE CLORURO DE HASTA EL 4,2% DE PESO.
