Abstract
Procedimiento para la obtención de cristales de carbonato de sodio monohidratado, según el cual se cristaliza carbonato de sodio monohidratado, según el cual se cristaliza carbonato de sodio monohidratado partiendo de una lejía acuosa carbonatada de hidróxido de sodio por encima de 35ºC y se separan los cristales de carbonato de sodio monohidratado y las aguas madres, caracterizado porque se cristaliza el carbonato de sodio monohidratado sobre gérmenes cristalinos de carbonato de sodio monohidratado obtenidos por evaporación, entre 35 y 107,5ºC, de una solución de carbonato de sodio exenta de hidróxido de sodio.
