Abstract

EL INVENTO CONCIERNE A UN PROCEDIMIENTO PARA LA PREPARACION DE ALUMINATO SODICO DE FORMULA GENERAL NAALO2, NAALO2.1,5 H2O Y/O NAALO2.XH2O POR REACCION DE OXIDO DE ALUMINIO HIDRATADO Y/O DE HIDROXIDO DE ALUMINIO CON UN EXCESO DE HIDROXIDO SODICO. PARA ELLO SE INTRODUCEN PRIMERAMENTE EN UN MEZCLADOR UNA SUSPENSION DE LOS COMPONENTES DE LA REACCION A UNA TEMPERATURA DE 20 A 120 (GRADOS) C, Y SE HACE PASAR A PRESION ESTA SUSPENSION A TRAVES DE, COMO MINIMO, UN TUBO DE REACCION CALENTABLE UNIDO AL MEZCLADOR. LA SOLUCION DE ALUMINATO SODICO QUE SE OBTIENE SE SECA POR PULVERIZACION, AJUSTANDO LA TEMPERATURA DE SALIDA DE LOS GASES UTILIZADOS PARA EL SECADO ENTRE 130 Y 190 (GRADOS) C.
