Reaction Steps
U.S. Pat. No. 2,433,601 discloses the preparation of a brine low in calcium sulfate content from crude brine by dissolving the crude sodium chloride in water containing small amounts of sodium carbonate or trisodium phosphate. In this process, it is important that the pH of the water be at least about 7 so that an insoluble precipitate of calcium carbonate or calcium phosphate is formed which can be removed.
