Abstract
SE PROPORCIONA UN METODO MEJORADO DE OBTENCION DE HIDROTALCITA SINTETICA, HACIENDO REACCIONAR PRIMERAMENTE OXIDO DE MAGNESIO EN POLVO CON ALUMINA FINA DE UN GRAN AREA SUPERFICIAL, EN SOLUCION O SUSPENSION, PARA FORMAR UN INTERMEDIARIO DE TIPO MEIXNERITA. DICHO INTERMEDIARIO SE PONE A CONTINUACION EN CONTACTO CON UNA FUENTE DE ANIONES, COMO UN ACIDO, Y CON MAYOR PREFERENCIA DIOXIDO DE CARBONO, PARA FORMAR EL HIDROXIDO DOBLE LAMELAR, QUE SE SEPARA DE LA SUSPENSION MEDIANTE FILTRACION, CENTRIFUGACION, DESHIDRATACION AL VACIO, U OTROS METODOS CONOCIDOS. SEGUN UNA REALIZACION PREFERIDA DE LA INVENCION, LA ALUMINA FINA COMBINADA CON EL OXIDO DE MAGNESIO, CONSISTE ESENCIALMENTE EN UN POLVO DE ALUMINA REHIDRATABLE, QUE TIENE UN AREA SUPERFICIAL DE 100 M{SUP,2}/G O MAYOR. PARA FABRICAR COMPUESTOS DE HIDROXIDOS DOBLES RELACIONADOS, SE PUEDE REEMPLAZAR EL DIOXIDO DE CARBONO ALIMENTADO A LA SUSPENSION, POR OTROS REACTIVOS, COMO BROMUROS, CLORUROS, ACIDOS BORICOS, O SALES DE LOS MISMOS.
