Abstract
10,361. Masson, C., and TilliÞre, C. April 26. Borax.-Relates essentially to using an ammonium salt instead of a sodium salt for obtaining borax from a mineral. An ammonium carbonate or sulphite is placed in the distilling-column A along with lime, and the vapours led off to water in an absorber B. The absorber is provided with an agitator and a heating-coil. The solution is then led to a digester C, into which the mineral is put, and carbonic acid is forced. The digester being closed, it is gradually raised from about 30‹ C. to about 130‹ to 135‹ C., and then lowered to 60‹ C., the pressure being maintained at about 2 atmospheres, and the liquid kept agitated. The latter is then transferred to a filter-press D, and the solution and wash liquor led to a reaction chamber E, having an agitator and a heating-coil, and into which is also placed the desired amount of sodium chloride. The solution is then passed to crystallizers G. The mother liquor is returned to the absorber B or column A. The mass left in A after each distillation is used as a part of the raw material in the digester, as it contains some borate. When, however, the amount of calcium sulphate increases to 25 to 30 per cent. of the mass, the latter is treated with ammonium carbonate to obtain a precipitate for use again in the digester, and also ammonium sulphate, which is distilled with lime in a separate column to obtain calcium sulphate as a residue, and ammonia suitable for re-use in the process. If ammonium sulphite or bisulphite is employed, calcium sulphite or bisulphite is obtained as a residue.
