Abstract

EN UN PROCEDIMIENTO PARA LA PRODUCCION DE PRECURSORES GRANULARES DE LIMPIADORES DE BAJA ALCALINIDAD PARA EL LAVADO A MAQUINA DE LA VAJILLA, COMPUESTOS DE SALES DE METALES ALCALINOS DEL ACIDO CARBOXILICO Y ACIDOS POLICARBOXILICOS ORGANICOS, SE DEBIA CONTRARRESTAR LA TENDENCIA A LA SEPARACION DEL PRODUCTO ACABADO. ESTO SE CONSIGUIO PREPARANDO UNA CANTIDAD PARCIAL DE LAS SALES DEL ACIDO POLICARBOXILICO SEGUN LA FORMA HABITUAL Y HACIENDO REACCIONAR A CONTINUACION, EN PRESENCIA DE ENTRE 2 Y 12 % EN PESO AGUA, EL CARBONATO ALCALINO EN PRESENCIA DE LAS SALES DE LOS METALES ALCALINOS DE LOS ACIDOS POLICARBOXILICOS CON LOS ACIDOS POLICARBOXILICOS LIBRES Y SUS SALES Y ESENCIALMENTE EN HIDROGENO CARBONATO ALCALINO A UNA TEMPERATURA INFERIOR A 60 (GRADOS) C.IN A PROCEDURE FOR THE PRODUCTION OF GRANULAR PRECURSORS OF LOW-ALKALINITY CLEANERS FOR THE MACHINE WASH OF THE TABLEWARE, COMPOUNDS OF SALTS OF ALKALINE METALS OF CARBOXYLIC ACID, IT IS SEPARATE TO PRODUCE A SINGLE AGENT. THIS WAS ACHIEVED BY PREPARING A PARTIAL AMOUNT OF THE SALTS OF THE POLYCARBOXYLIC ACID ACCORDING TO THE REGULAR FORM AND BY REACTING THEN, IN THE PRESENCE OF BETWEEN 2 AND 12% IN WATER WEIGHT, THE ALCALINE CARBONATE IN THE PRESENCE OF THE SALTS OF THE ALCALAL METALS POLYCARBOXYLICS WITH FREE POLYCARBOXYL ACIDS AND THEIR SALTS AND ESSENTIALLY IN ALKALINE HYDROGEN CARBONATE AT A TEMPERATURE LESS THAN 60 (DEGREES) C.
