    For the polarographic determination of tin in the presence of tungsten, a supporting electrolyte of 5±0.5N hydrochloric acid is recommended. In 6N, 8N and 10N hydrochloric acid media, the half-wave potentials of tungsten are -0.71v,-0.65v and -0.61v vs. S.C.E. respectively, all of them are virtually coincident with those of tin wave. However, in 5±0.5Nhydrochloric acid media, large portion of tungstic acid precipitates and the half-wave potential of the trace tungstic acid remaining in the solution...

    For the polarographic determination of tin in the presence of tungsten, a supporting electrolyte of 5±0.5N hydrochloric acid is recommended. In 6N, 8N and 10N hydrochloric acid media, the half-wave potentials of tungsten are -0.71v,-0.65v and -0.61v vs. S.C.E. respectively, all of them are virtually coincident with those of tin wave. However, in 5±0.5Nhydrochloric acid media, large portion of tungstic acid precipitates and the half-wave potential of the trace tungstic acid remaining in the solution shifts to a more negative value of -0.75v vs. S.C.E., while that of tin in the same media remains at -0.58v vs. S.C.E.. Hence the interference of tungsten becomes negligible.

    本文述說在5±0.5N之鹽酸底液中錫有穩定正常的還原波,而鎢酸在此酸度絕大部分形成沉澱。在溶液中未完全沉澱之痕量鎢所產生的還原波在錫波後0.17伏恃處,僅使錫波波尾微陡斜,而不影響錫之波高测量。並且此陡形可因延長沉澱放置時間而消除。因此可不用事先分離鎢而直接测定合鎢礦石中錫之含量。

    A new iodine heterocycle, 3,6-dinitro-dibenzopyriodonium bisulfate (Ⅲa), prisms, m.p. 217.5° (dec.), was found to be readily prepared in 86% yield by treating 4,4'-dinitrodiphenylmethane with iodosyl sulfate, which was conveniently obtained by stirring a stoichiometric mixture of iodine and sodium iodate in concentrated sulfuric acid. The iodonium compound (Ⅲa) could be converted to the chloride (Ⅲb), colorless needles, m.p. 211.5° (dec), bromide (Ⅲc), yellowish needles. m.p. 217.5° (dec.), iodide (Ⅲd), yellow powder, m.p. 164° (dec.) and picrate (Ⅲe), yellow needles, m.p. 183-184° (dec.) by treating its solution in formic acid with a 50% formic acid solution of sodium chloride, sodium bromide or potassium iodide or with an alcoholic solution of picric acid respectively. The structural formula (Ⅲ) of the new iodonium compounds was derived by means of potassium permanganate oxidation of the bisulfate (Ⅲa) to 2-iodo-4-nitrobenzoic acid, and by thermal decomposition of the iodide (Ⅲd) to 2,2'-diiodo-4, 4'-dinitro-diphenyl-methane (Ⅵ) (60% yield), m.p. 158-159°, the structure of which was shown by analysis and by comparison with what is known about the behavior of other iodonium iodides, e.g., 4,4'-dicarboethoxy-diphenylene iodonium iodide (Ⅷ), which decomposes on heating yielding 2,2'-diiodo-4,4'-dicarboethoxydiphenyl (Ⅸ). Compound (Ⅵ) could be reduced with tin and hydrochloric acid to a diamino compound (Ⅶ).The iodonium salt (Ⅲa) possessed the interesting property that when it was treated with dilute sodium hydroxide solution at room temperature with the addition of ethyl acetate or pyridine, a beautiful bluish-green color gradually developed in the organic layer. When it was heated with dry pyridine, the same color developed. The colored ethyl acetate solution changed to brownish yellow on acidification with dilute sulfuric acid and regained its bluish-green color when the acidified solution was made alkaline.Under similar conditions as described above, reaction between diphenylmethane and iodosyl sulfate gave a grayish substance, m.p. 210-212°, which was insoluble in common solvents. This substance was possibly a polymeric compound of formula (Ⅺ).
