Abstract

1502850 Purification of Na 2 CO 3 APPLIED CHEMICAL CORP 9 Dec 1975 [9 Dec 1974] 50444/75 Heading C1A NaF is removed from Na 2 CO 3 by adding the Na 2 CO 3 to a saturated aqueous solution of both Na 2 CO 3 and NaF having dissolved Na 2 CO 3 in equilibrium with solid Na 2 CO 3 monohydrate which is subsequently separated from the NaF solids, e.g., by sizing.
