摘要:
High purity, chloride- and alkali metal-free copper (II) alkoxides are prepared by the reaction of an alcoholic alkali metal alkoxide solution with copper (II) fluoride; ammoniating the resulting solution to render soluble the resulting copper (II) alkoxide; and filtering the resulting solution to obtain an alkali metal- and chloride-free alcoholic copper (II) alkoxide solution. The resulting solution is useful in the preparation of superconducting compounds such as yttrium-barium-copper oxide superconductor.
