Since the 1970’s, Bayer of Germany had been producing tantalum (V) ethoxide in Leverkusen, however following the break-up of Bayer, production moved to Heraeus. Meanwhile, Inorgtech (later MultiValent), started production in 1974 in Cambridge, UK. Both routes involved the direct reaction of the metal chloride with alcohol in the presence of solvents to give a product of 99.999%+ purity.
