“…Since the first mention of the ether extraction of molybdenum from a hydrochloric acid solution by Pechard in 1892 (18), methods for the separation of molybdenum by extraction have been discussed by many authors. In general, these methods involve the extraction of molybdenum cupferrate by chloroform (1,7,20) or ethyl nitrate (21), the extraction of molybdenum thiocyanate by various organic solvents (8,14,19,22), the extraction of molybdenum dithiol by butyl or amyl acetate (9, 28), and the extraction of molybdenum from mineral acids into organic media (3,15,19,24)• Of these methods, the extraction of molybdenum from mineral acids with an organic solvent utilizes the most simple system, and the investigation performed by Xelidow and Diamond (15) indicates that this separation can lie highly efficient, depending on the solvent and acidities used. From their study, the extraction of molybdenum from 6 to 7M hydrochloric acid by hexone (4methyl-2-pentanone) was shown to be about 96% efficient; the efficiency of the usual diethyl ether extraction is less.…”
