The effects of copper and zinc ionsupon the precipitation of barium sul-phate have been noted for a long time.However,the results published wereeither not systematic(3,4b,5,6)or obtained under conditions apart fromusual analytical practice(7,8).Thus,it seems necessary to investigate thissubject in more detail by the usual methods of determination.The presentcommunication reports(a)the effect of various amounts of cupric and zincions and(b)the influence of different acidities during precipitation in thepresence and absence of zinc ions.It is found that the interference of copper in the determination of sulphuras barium sulphate up to a ratio of 20:1 for Cu:S is negligible.The deviationsof the results obtained from theoretical values are all within ±2‰(see Table1),and do not show any regularity with the amount of copper added.The presence of zinc ions alone gives satisfactory results(slightly lowerthan theoretical values).As the amount of zinc ions in solution increases,thedeviations become somewhat wider(Table 2).The low results are presumedto be due to(1)the formation of soluble zinc-sulphate complex,which holdsa part of sulphate in solution,and/or(2)diverse ion effect.In the presenceof zinc ions,introducing hydrochloric acid up to 0.1 N before precipitationcauses essentially the same errors as if hydrochloric acid were absent(cf.Tables2 and 3),while at and beyond 0.2 N positive errors are obtained.A spectrographic examination of the precipitates reveals that zinc doescoprecipitate with barium sulphate,though only to a slight extent.The amountof zinc coprecipitated decreases with the increase of the acidity of the solutionfrom which the precipitate is thrown down.

Aureomycin (Ⅰ) on reduction with zinc-acetic acid gives desdimethylaminoaureomycin (Ⅱ) under mild conditions and desdimethylaminodesoxyaureomycin (Ⅲ) under more drastic conditions. Ⅱ can be converted into Ⅲ by further reduction. Treatment of Ⅰ, Ⅱ or Ⅲ with concentrated hydrochloric acid or methanolic HCl produces anhydroaureomycin (Ⅳ), desdimethylaminoanhydroaureomycin (Ⅴ) or desdimethylaminodes- oxyanhydroaureomycin (Ⅵ) respectively. Compound (Ⅴ) can be obtained from Ⅳ by hydrogenolysis, and, similarly, Ⅵ...

Aureomycin (Ⅰ) on reduction with zinc-acetic acid gives desdimethylaminoaureomycin (Ⅱ) under mild conditions and desdimethylaminodesoxyaureomycin (Ⅲ) under more drastic conditions. Ⅱ can be converted into Ⅲ by further reduction. Treatment of Ⅰ, Ⅱ or Ⅲ with concentrated hydrochloric acid or methanolic HCl produces anhydroaureomycin (Ⅳ), desdimethylaminoanhydroaureomycin (Ⅴ) or desdimethylaminodes- oxyanhydroaureomycin (Ⅵ) respectively. Compound (Ⅴ) can be obtained from Ⅳ by hydrogenolysis, and, similarly, Ⅵ from either IV or V. All the above compounds, (Ⅰ), (Ⅱ), (Ⅲ), (Ⅳ), (Ⅴ) and (Ⅵ), when subjected to zinc dust distillation, form naphthacene. A comparison of the ultra-violet absorption spectra of Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ and Ⅵ affords a supplementary evidence for the location of the angular-OH group in the structure of aureomycin.

金黴素(I)在冰醋酸與甲醇溶液中,用鋅粉氫解,在温和條件下,產生脫二甲胺金黴素(II);較劇烈條件下,則生成脫二甲胺脫羥金黴素(III)。III從II經鋅粉醋酸氫解得到。 I,II,III分別與濃鹽酸或甲醇鹽酸處理相應地得到脫水金黴素(IV),脫二甲胺脫水金黴素(V)及脫二甲胺脫羥脫水金黴素(VI)。脫水金黴素(IV)經鋅粉醋酸氫解亦產生V與VI。VI亦可從V製成。 I,II,III,IV,V或VI和鋅粉共同蒸餾,皆得到并四苯。 從紫外吸收光譜測定,對金黴素結構中二甲胺基及角羥基的位置有補充的說明。
