| titleOfInvention | Process of preparing sodium carbonate peroxide |
| abstract | 1466474 Sodium percarbonate FMC CORP 24 Dec 1974 55677/74 Heading C1A Aqueous solutions of H 2 O 2 (cone. of 17- 50 gl<SP>-1</SP>) and Na 2 CO 3 (150-250 gl<SP>-1</SP>) are reached continuously at a pH of 11À2 to 11À7, temperature of 25‹-34‹ C., and residence time of 2-8 hrs. in the presence of 10-70 p.p.m. Mg as magnesium silicate and 0À005-0À5 gl<SP>-1</SP> of sodium silicate, the crystalline slurry of sodium percarbonate is removed from the crystallization zone, filtered and dried; the mother liquor is returned to the crystallizer and excess water is evaporated from the system while continuously introducing fresh Na 2 CO 3 and H 2 O 2 solutions. In an example, a hydrogen peroxide efficiency of 80-85% was obtained at 300‹ C. and the crystals were larger (20% of +50 mesh, 70% of +100 mesh). |
