Abstract

PROCEDIMIENTO PARA PREPARAR PERSULFATO POTASICO DE ELEVADA PUREZA CON CONTENIDO REDUCIDO DE SULFATO POTASICO POR LA REACCION DE PERSULFATO AMONIMO E HIDROXIDO POTASICO, CARACTERIZADO PORQUE AL MENOS PARTE DEL HIDROXIDO POTASICO USADO COMO MATERIAL DE PARTIDA SE AÑADE A AL MENOS PARTE DE LAS AGUAS MADRES DESPUES DE LA SEPARACION DE LOS CRISTALES DE PERSULFATO POTASICO OBTENIDOS POR DICHA REACCION PARA PRECIPITAR Y SEPARAR EL SULFATO POTASICO FORMADO POR LA DESCOMPOSICION DE PERSULFATO POTASICO, Y SE RECICLAN LAS AGUAS MADRES.PROCEDURE TO PREPARE HIGH PURITY POTASSIC PERSULFATE WITH REDUCED CONTENT OF POTASSIC SULPHATE BY THE REACTION OF AMONYMOUS PERSULFATE AND POTASSIUM HYDROXIDE, CHARACTERIZED BECAUSE AT LEAST PART OF THE SOUTHEAST DEPARTMENT OF SOUTHEAST DEPARTMENT SEPARATION OF THE POTASSIC PERSULPHATE CRYSTALS OBTAINED BY SUCH REACTION TO PRECIPITATE AND SEPARATE THE POTASSIC SULPHATE FORMED BY THE DECOMPOSITION OF POTASSIC PERSULPHATE, AND THE MOTHER WATERS ARE RECYCLED.
