The extent of coprecipitation of copper with ferric hydroxide in the am- monium chloride-ammonia process has been studied. Pentavalent arsenic and antimony may be present up to 10 mg, and phosphate, 50 mg. Aluminum exerts little effect. It is found that this method yields satisfactory results. The amount of copper coprecipitated in the ferric hydroxide precipitate is negligible in practical analysis.

用氫氧化銨及氯化銨以分離銅與鐵,結果很好。氫氧化鐵中所留銅量,在實用分析上,已少至毋須考慮。用此法自多量鐵中分離少量銅份,可直接用此色法测定。五價砷與銻存在時,如不超過10毫克,或磷酸根不超過50毫克時,不影響銅與鐵的分離。鋁對分離更無影響。

p-Nitro-acetophenone was prepared by diazotizing p-amino-acetophenone in fluoroboric acid solution and replacing the diazonium fluoroborate group by the nitro group in presence of finely divided copper as catalyst. Yield 55-60%; m.p. 76-78℃. Recrystallization from alcohol gave a product of m.p. 80℃.

從乙醯苯胺、醋酸酐與氯化鋅作用,經水解後製得對胺基苯乙酮。在氟硼酸水溶液中重氮化之,再在亞硝酸鈉的水溶液中以銅粉為觸媒,將此重氮團置換成爲硝基,即得對硝基苯乙酮。

p-Nitrobromobenzene was prepared from the sodium salt of α-p-Nitrophe-nyl-β-acetyl-hydrazine by bromination and subsequent addition of copper catalyst.Similary,α-p-nitrophenyl-pyridine was obtained by adding pyridine instead ofcopper catalyst.

(一)α-对硝基苯-β-乙醯肼钠盐溴化后,加进铜催化剂,即有放氮效应,产品为对硝基溴苯。(二)用吡啶代替铜催化剂,亦放出氮气,产品为α-对硝基苯吡啶.
