Abstract

Se describen composiciones y metodos para mejorar la inhibicion de la formacion de incrustaciones de sales de calcio bajo las condiciones presentes en procedimientos quimicos de reduccion a pasta, en los cuales una cantidad efectiva de fosfonatos o mezclas de fosfonatos seleccionados se mezcla con la composicion acuosa de la lejiadora en un procedimiento quimico de reduccion a pasta durante la etapa de digestion; las composiciones y el metodo son especialmente bien adecuados para su uso en el procedimiento de reduccion a pasta Kraft.
