Abstract

SE DESCRIBE UN PROCESO PARA LA PRODUCCION DE CICLOHEXANODIMETANOL POR HIDROGENACION DE UN CICLOHEXANODICARBOXILATO DE DIALQUILO QUE CONSISTE EN A) PREVER UNA ZONA DE HIDROGENACION QUE CONTIENE UNA CARGA DE UN CATALIZADOR DE HIDROGENACION DE ESTER HETEROGENEO GRANULAR; B) FORMAR UNA CORRIENTE DE ALIMENTACION VAPOROSA DE UN GAS QUE CONTIENEN HIDROGENO Y UN MATERIAL HIDROGENABLE QUE COMPRENDE UN DIALQUILO CICLOHEXANODICARBOXILATO A UNA TEMPERATURA DE ALIMENTACION QUE ESTA EN LA GAMA DE APROXIMADAMENTE 150 (GRADOS) C A APROXIMADAMENTE 350 (GRADOS) C Y QUE ESTA POR ENCIMA DE UN PUNTO DE ROCIO DE LA CORRIENTE DE ALIMENTACION Y A UNA PRESION DE ALIMENTACION QUE VA DE APROXIMADAMENTE 150 PSI (APROXIMADAMENTE 10.34 BARES) A APROXIMADAMENTE 2000 PSI (APROXIMADAMENTE 137.90 BARES), TENIENDO DICHA CORRIENTE DE ALIMENTACION VAPOROSA UNA RELACION GAS QUE CONTIENEN HIDROGENO: CICLOHEXANODICARBOXILATO DE DIALQUILO CONOCIDA. C) SUMINISTRAR LA CORRIENTE DE ALIMENTACION VAPOROSA A LA ZONA DE HIDROGENACION; D)MANTENER LAS CONDICIONES DE HIDROGENACION EN LA ZONA DE HIDROGENACION QUE ES EFECTIVA PARA MANTENER LA MEZCLA DE REACCION EN CONTACTO CON EL CATALIZADOR DE HIDROGENACION POR ENCIMA DE SU PUNTO DE ROCIO; Y E) PASAR LA CORRIENTE DE ALIMENTACION VAPOROSA A TRAVES DE LA ZONA DE HIDROGENACION; Y F) RECUPERAR DE LA ZONA DE HIDROGENACION UNA CORRIENTE DE PRODUCTO QUE CONTIENEN CICLOHEXANODIMETANOL. EN ESTE PROCESO SE PREFIERE USAR 1,4CICLOHEXANODICARBOXILTO DE DIMETILO PARA PRODUCIR 1,4CILOHEXANODIMETANOL.
