铼是石油工业及合成纤维工业中做催化剂的重要原料,在高温合金及电子工业中都有广阔的用途。近年来国内外对从生产钼流程中用溶剂萃取法提取铼的研究颇为重视。 目前提取铼的萃取剂主要用异戊醇、叔胺及季胺盐。采用异戊醇的主要问题是萃取剂损耗大,成本高;叔胺萃取剂虽有萃取能 Rhenium is an important raw material for catalysts in the petroleum industry and the synthetic fiber industry, and has a wide range of applications in the superalloys and electronics industries. In recent years, domestic and foreign researches on the extraction of rhenium by solvent extraction from the production of molybdenum have received considerable attention. At present extraction of rhenium is mainly used isoamyl alcohol, tertiary amine and quaternary ammonium salt. The main problem with isoamyl alcohol is the large loss of extractant and the high cost. Although tertiary amine extractant can be extracted
