Complexing agent modified hexacyanometallate hexanitrometallate catalyst

摘要

Metal [hexacyanometallate hexanitrometallate] complexes are useful alkylene oxide polymerization catalysts. The metal is any that forms a precipitate with hexacyanometallate and hexanitrometallate groups. These catalysts are made from less expensive raw materials than the common zinc hexacyanocobaltate catalysts, and provide short induction periods and in many cases more controlled exotherms.
