| 内容記述 | For the purpose of manufacturing bromine from marine algae, some series of experiments were carried out. (1) It was proved that the aeration method with sulphuric acid and potassium iodate was applicable to estimate the amount of bromine in the presence of much chlorides, and that it was possible to use the above method to the determination of bromine in marine algae. (2) Some 40 species of marine algae, collected at the coast of Hokkaido and karafuto, were examined for bromine contents by above method, and it was found out that some species of Rhodomelaceae (Rhodophyceae), contained for greater amount of bromine than other algae, and that the forecast production, calculated roughly by the investigation of the distribution and growing state of these, would enable us to utilize these as an industrial material. |

| 内容記述 | (3) Some factors, which had to be performed in manufacturing bromine from that algae by kelp method, were researched, and the results obtained wereas follows: a) The parallel procedure in manufacturing iodine, might be applied to that of burning algae and of extracting bromine from kelp. b) Potassium salts are to be produced by the concentration of extracts, but it was hardly possible to make the yield of potassium salts sufficient as long as the recovery of bromine was the first purpose. c) The recovery of bromine in the case of the concentrated extracts was more profitable on the yield, adding weight of chemicals etc., than the dilute solution. d) Potassium chlorate was more suitable as the oxidizer in distilling bromine from mother solution, than managanese dioxde, sodium chromate etc. |

| 内容記述 | (4) The often-repeated test of manufacturing bromine from the algae of Rhodomelaceae, enabled us to ascertain that about 90~95% of bromine in the algae was to be recovered by simple apparatus and procedure with some quantities of potassium salt. (5) It was found out that the rest-solution of iodine manufacture contained considerable amount of bromine, and that it was more simple and profitable than manufacturing directly bromine from the rest solution only, to apply it to the process of extracting bromine from kelp of Rhodomelaceae. (6) Some considerations were given from a industrial point of view, on manufacturing bromine from the algae of Rhodomelaceae, and from the rest-solution of iodine manufacture. |
