苯胲与亚硝酸钠在酸性介貭中可以形成N-亚硝基苯胲(其铵盐称为铜铁试剂)。Heyn和Dave利用这一反应研究了N-亚硝基苯胲铜(Ⅱ)、铁(Ⅲ)及钛(Ⅳ)盐的均匀沉淀,指出,所得沉淀无过量试剂沾污,且易于过滤和洗涤。有可能改进铜铁试剂在重量测定和分离方面的某些欠缺。因此,本文研究了N-亚硝基苯胲锆的均匀沉淀。
Benzoin and sodium nitrite can form N-nitrosobenzene in acidic medium (its ammonium salt is called copper and iron reagent). Heyn and Dave used this reaction to study the uniform precipitation of N-nitrosobenzophenanthronium (II), iron (III) and titanium (IV) salts and indicated that the resulting precipitate was free from excessive reagent contamination and was easily filtered and washed . It is possible to improve some of the deficiencies in the determination and separation of copper and iron reagents. Therefore, we studied the uniform precipitation of N-nitrosobenzirconium.
