摘要
研究了伯胺(简写作N_(1923)或RNH_2)在中性溶液中和伯胺盐在酸性溶液中对钨(Ⅵ)的萃取过程以及酸度、温度等影响,用饱和法和摩尔系列法研究了萃合物的组成,并对萃合物的红外光谱和核磁共振谱进行了分析。在此基础上,对伯胺萃取钨存在着两种不同的机理进行了讨论。
The extraction of tungsten (Ⅵ) from neutral and aciditysolutions by primary amine (abbreviated as N_(1923) or RNH_2) in kerosenehas been investigated, and the effects of the acidify of the aqueos phase,temperature and the added acid amount on this extraction process have beenexamined. The isomoler series method, the component in the saturatedorganic phase, the infrared and NMR spectra of organic phases have alsobeen studied. The mechanism of extraction is discussed on the basis of theresults obtained.
