Abstract

250,208. Deguide, C. April 3, 1925, [Convention date]. Purifying saccharine liquids.-Barium silicates, including the mono, di, and tri-barium silicates, and the silicates intermediate between the mono- and di- and between the di- and tri-barium silicates, when they have become contaminated with silica or alumina in use, for instance, in the treatment of sugar solutions and subsequent regeneration, are suspended in water and treated with carbonic acid to convert the barium into carbonate with the separation of silica and alumina. The insoluble material is then treated with caustic soda or potash to dissolve the silica and alumina, leaving barium carbonate which is then calcined with silica to produce the original barium silicate. The treatment with carbonic acid need not be complete, but may be discon. tinued when the necessary amount of silica has been removed, so that the product when calcined will be again suitable for the treatment of sugar solution. Specifications 110,537 and 174,052. both in Class 1 (iii), Oxides &c., Metallic], are referred to.
