Abstract

PROCEDIMIENTO DE PREPARACION DE HIDROXICLORUROS DE ALUMINIO DE FORMULA (I), EN LA QUE X ES SUPERIOR O IGUAL A 5. SE TRATA DE HACER REACCIONAR UNA ALUMINA ALTAMENTE REACTIVA CON UNA SOLUCION DE ACIDO CLORHIDRICO Y DE CLORURO DE ALUMINIO. LA ALUMINA POSEE UNA ESTRUCTURA AMORFA DE SUPERFICIES ESPECIFICA SUPERIOR A 600 M. CUADRADOS/G.; ESTA ALUMINA SE HA OBTENIDO DESCOMPONIENDO TERMICAMENTE CARBONATO DOBLE DE ALUMINIO Y AMONIO DE FORMULA (II) A UNA TEMPERATURA COMPRENDIDA ENTRE 200 Y 500GC DURANTE UN TIEMPO COMPRENDIDO ENTRE FRACCIONES DE SEGUNDO Y 5 HORAS. LA CONCENTRACION DE HCL ES DE 3 N; LA SOLUCION DE CLORURO DE ALUMINIO TIENE UNA CONCENTRACION COMPRENDIDA ENTRE 0,25 N Y 1,7 N. LA RELACION MOLAR AL2O3/HCL ESTA COMPRENDIDA ENTRE 0,95 Y 1,05. (I) AL2(OH)XCL6-X (II) ALNH4CO3(OH)2.
