Abstract

Se describe un proceso para la preparacion de soluciones o suspensiones concentradas de compuesto organicos anionicos, proceso el cual comprende a) acidificar una solucion o dispersion acuosa de un compuesto organico anionico que comprende sales y/o impurezas, a un pH de 4.5 o menos, si el pH se encuentra por encima de ese valor, de modo que b) el compuesto organico anionico se vuelve soluble en agua y precipita en forma de acido libre, c) llevar la suspension, por medio de micro o ultrafiltracion, a un contenido de sal de menos del 2% en peso, sobre la base del peso total del material requerido, con d) lavado opcional de las sales con agua a un pH menor de 4.5, e) lavando entonces opcionalmente con agua hasta el acido libre, entonces f) incrementando la concentracion de modo que el contenido de compuesto organico anionico sea del 5 al 50% en peso, y g) disolviendo opcionalmente el compuesto anionico mediante la adicion de una base adecuada.
