Abstract
For use in bleaching solid stable addition products of sodium hypochlorite and inorganic salts which are capable of combining with water of crystallization such as sodium phosphates, sodium metasilicate, or soda are obtained by melting the salts in their water of crystallization and mixing the molten mass at 90-125 DEG C. with sodium hypochlorite solutions, solidification being effected by surface cooling, as by running the mixture on to cold surfaces or cooled rotating drums. The salts employed may be partly dehydrated during fusion or have added to them partially or wholly dehydrated salts. Examples relate to the preparation of mixtures of trisodium phosphate and sodium hypochlorite containing from 2,53 to 4,30 per cent of active chlorine.ALSO:Solid stable crystalline addition products of sodium hypochlorite and inorganic salts which are capable of combining with water of crystallization such as sodium phosphates, sodium metasilicate, or soda are obtained by melting the salts in their water of crystallization and mixing the molten mass at 90-125 DEG C. with sodium hypochlorite solutions, solidification being effected by surface cooling, as by running the mixture on to cold surfaces or cooled rotating drums. The salts employed may be partly dehydrated during fusion or have added to them partially or wholly dehydrated salts. Examples relate to the preparation of mixtures of tri-sodium phosphate and sodium hypochlorite containing from 2,53 to 4,30 per cent of active chlorine.ALSO:Solid stable addition products of sodium hypochlorite and inorganic salts which are capable of combining with water of crystallization such as sodium phosphates, sodium metasilicate, or soda are obtained by melting the salts in their water of crystallization and mixing the molten mass at 90-125 DEG C. with sodium hypochlorite solutions, solidification being effected by surface cooling, as by running the mixture on to cold surfaces or cooled rotating drums.
