Abstract : Electrochemical, spectroscopic and spectroelectrochemical studies of tantalum, niobium, tungsten and rhenium were conducted in molten alkali haloaluminate melts. The melts were in most cases treated with COl4 to remove o)dde. Evidence was found for the formation of metallic tantalum, niobium and tungsten during controlled potential electrolysis in these melts. No conclusive evidence was found for rhenium plating. Reaction sequences, based on experimental data, were proposed for the four metals. Organic studies involved the chemistry and electrochemistry of tetrachloro-p-benzoquinone in molten chloroaluminates and the photochemical reactions of anthracene and 9-methylanthracene in EMIC/AlCI3 melts.
