Abstract

Un proceso para preparar partículas de bicarbonato de sodio, donde el proceso comprende los pasos de: (a) agregar por lo menos un carbonato de metal alcalino a una solución acuosa para formar una composición acuosa, donde el carbonato de metal alcalino comprende carbonato de sodio y donde la composición acuosa comprende por lo menos un ácido policarboxílico y/o sales del mismo, en una cantidad de por lo menos 200 ppm en base al peso de la composición acuosa, y (b) separar el bicarbonato de sodio de la composición acuosa, para obtener partículas de bicarbonato de sodio, por un lado, y unas aguas madres acuosas, por otro lado.
