Abstract
PROCEDIMIENTO PARA SEPARA SICLOHEXANOL DE SOLUCIONES ACUOSAS CONTENIENDO ACIDO SULFONICO AROMATICO. EL CICLOHEXANOL SE OBTIENE A TRAVES DE: HIDRATAR EL CICLOHEXENO CON SOLUCIONES ACUOSAS DE ACIDO SULFONICOS AROMATICOS A ELEVADA TEMPERATURA Y SEPARA EL CICLOHEXENO SOBRANTE MEDIANTE DESTILACION CON VAPOR DE AGUA. EL PROCEDIMIENTO SE CARACTERIZA PORQUE EL CICLOHEXANOL Y LA SOLUCION ACUOSA CONTENIENDO ACIDO SULFONICO AROMATICO SE SUMINISTRA POR EL TERCIO SUPERIOR DE UNA PRIMERA COLUMNA RECTIFICADORA; 1 A 50 PARTES EN PESO DE VAPOR DE AGUA POR PARTE EN PESO DE CICLOHEXANOL SE SUMINISTRA POR EL TERCIO INFERIOR DE LA COLUMNA RECTIFICADORA; DE LA CABEZA DE LA COLUMNA RECTIFICADORA SE EXTRAEN VAPORES CONSISTENTES EN CICLOHEXANOL CICLOHEXENO Y AGUA; DE LA COLA DE LA COLUMNA RECTIFICADORA SE RECOGE UNA SOLUCION ACUOSA DE ACIDO SULFONICO AROMATICO; EL VAPOR EXTRAIDO POR LA CABEZA DE LA COLUMNA RECTIFICADORA SE CONDENSA Y SE OBTIENE UNA FASE RICA EN CICLOHEXANOL Y UNA FASE ACUOSA; LA FASE ACUOSA OBTENIDA SE EMPLEA PARA PRODUCIR VAPOR DE AGUA NECESARIA EN EL PROCESO; EL RESTO DE LA FASE ACUOSA SE EMPLEA PARA LA HIDRATACION DE CICLOHEXENO; LA FASE RICA EN CICLOHEXANOL SE DESTILA EN UNA SEGUNDA COLUMNA RECTIFICADORA OBTENIENDOSE UNA MEZCLA DE AGUA Y CICLOHEXENO Y ALGO DE CICLOHEXANOL POR LA CABEZA DE LA COLUMNBA RECTIFICADORA Y SE EXTRAE EL CICLOHEXANOL COMO PRODUCTO DE COLA.
