| abstract | 308,281. Govett, Ltd., (Assignees of Govett, E.). March 20, 1928, [Convention date]. Bromine : iodine.-Water-soluble colloidal forms of iodine and bromine are obtained by causing the halogen to react with gallic or tannic acid to produce hydrogen halide, converting this into an insoluble metallic halide, and decomposing this to yield the halogen in a colloidal and probably hydrated form. For example, iodine is treated with tannic or gallic acid, and a nitrate or acetabe of lead, silver, copper, bismuth, thallium, or mercury is then added. The insoluble iodide is removed and decomposed by treatment with a strong acid or with bromine, and the colloidal iodine is obtained by evaporating the resulting solution to dryness. Bromine can be obtained by a similar method, or by a modified method which consists in treating potassium bromate with tannic acid, heating and adding nitric acid, allowing the insoluble tannate to settle, and filtering, leaving hydrogen bromide in solution. Upon evaporating this, a hydrated bromine is obtained. |
