Abstract

A.LE PROCEDE EST DESTINE A FABRIQUER UN PERCARBONATE DE SODIUM EN GRAINS GROSSIERS PAR REACTION DE PEROXYDE DE SODIUM AVEC DU CARBONATE DE SODIUM A 10 A 20C. B.ON PREPARE UNE SOLUTION CONTENANT DU CARBONATE DE SODIUM ET DE L'HEXAMETAPHOSPHATE DE SODIUM DANS LE RAPPORT DE 65:1 A 500 A 1, ET SATUREE DE PERCARBONATE DE SODIUM, PUIS ON AJOUTE UNE QUANTITE DE HO, EQUIVALENTE A LA QUANTITE DE CARBONATE DE SODIUM, LE PERCARBONATE DE SODIUM PRECIPITANT EN RAISON DE LA SURSATURATION QUI SE PRODUIT. C.CE PROCEDE PERMET D'OBTENIR UNE PROPORTION DOMINANTE DE PERCARBONATE EN POUDRE GROSSIERE AVEC UN MINIMUM DE FINES.
