Solvent extraction of rhenium from molybdenum in
2009-7-1 From Fig. 1 it is found that the molybdenum extraction capacities of the mixture of 20% N235 and 20% sec-caprylic alcohol diluted kerosene oil for rhenium and molybdenum are almost the same. Whilst Fig. 2 shows that mixture of 20% N235 and 30% tributyl phosphate diluted kerosene oil has lower extraction capacities of molybdenum than that of rhenium, this shows that tributyl phosphate has ...

Stephanie on Science : Is Molybdenum-Rhenium The
2015-11-2 Further, MoRe is biocompatible, MRI and CT compatible, corrosion resistant, ductile, and features high tensile strength. This substantial strength and durability implies that it is a long-term solution for orthopedic problems; however, this comes at a high cost, at nearly US$5,000 per kilogram of Rhenium, as of 2010.

Rhenium-Catalyzed Epoxide Deoxygenation: Scope
Transfer of oxygen atoms from epoxides to triphenylphosphine is efficiently catalyzed by Tp'ReO 3 [Tp' = hydrido-tris-(3,5-dimethylpyrazolyl)borate] in benzene at 75-105 °C. The reaction tolerates a wide variety of functional groups including ketones (conjugated or non-conjugated to the new double bond), esters, nitriles, ethers, silyl ethers and phthalimides. Relative rates vary with ...
