Abstract
SE DESCRIBE UN PROCESO PARA ELABORACION DE BETA-YONONA A TRAVES DE LA CICLIDIZACION CATALIZADA CON ACIDO SULFURICO DE SEUDOYONONA CON UN SISTEMA DE DISOLVENTE DE DOS FASES COMPUESTO A PARTIR DE ACIDO SULFURICO CONCENTRADO Y UN SEGUNDO DISOLVENTE ESENCIALMENTE NO MISCIBLE CON AGUA, DONDE EL PROCEDIMIENTO ESTA CARACTERIZADO POR LA UTILIZACION DE DIOXIDO DE CARBONO LIQUIDO QUE SE ENCUENTRA BAJO PRESION. ENTRE OTRAS COSAS ESTE PROCESO SE REALIZA BAJO UNA PRESION DESDE APROXIMADAMENTE 50 BAR HASTA APROXIMADAMENTE 150 BAR Y ANTES DE LA ROTURA DE CONEXION (APLASTAMIENTO) DE LA REACCION DE CICLIDIZACION EN TEMPERATURAS DESDE APROXIMADAMENTE 15 PROCESO DE ACUERDO CON LA INVENCION SE REALIZA PREFERENTEMENTE DE FORMA CONTINUA Y REPRESENTA UNA ETAPA INTERMEDIA IMPORTANTE EN LA SINTESIS DE LA VITAMINA A.
