Abstract

PROCEDIMIENTO PARA LA OBTENCION DE PREPARACIONES DE DITIONITO SODICO ESTABILIZADAS. COMPRENDE: DISOLVER SALES SODICAS Y/O POTASICAS INERTES, TALES COMO FORMIATO SODICO, ACETATO SODICO, LA SAL SODICA DEL ACIDO OXIMETANSUFINICO, CARBONATO POTASICO Y/O SULFITO POTASICO, FRENTE AL DITIONITO SODICO CON UNA SOLUBILIDAD EN AGUA SUPERIOR A 500 G/L A 20C EN UNA CANTIDAD DE AL MENOS 200 G/L DE AGUA, PARA OBTENER UNA SOLUCION SALINA Y COMBINAR LA SOLUCION SALINA CON DITIONITO SODICO EN CANTIDADES TALES QUE LA MEZCLA FORMADA PRESENTA LA CONSISTENCIA DE UNA PASTA BOMBEABLE, PRESENTANDO UNA VISCOSIDAD DE 0,1 A 1.500 PA.S. SIENDO LA PROPORCION EN DITIONITO EN LAS PASTAS PREPARADAS DEL 60 AL 70% EN PESO; DEL 15 AL 30% EN PESO DE AGUA; Y EL RESTO HASTA EL 100% ENTRE LAS SALES SOLUBLES ASI COMO LOS HIDROXIDOS. SE UTILIZA COMO AGENTES DE REDUCCION O BLANQUEANTES, POR EJEMPLO EN EL BLANQUEO DE PULPA DE MADERA.
