Double-metal cyanide catalysts of the formulaM1 is a metal ion selected from the group consisting of Zn2+, Fe2+, Co3+, Ni2+, Mn2+, Co2+, Sn2+, Pb2+, Mo4+, Mo6+, Al3+, V4+, V5+, Sr2+, W4+, W6+, Cr2+, Cr3+ and Cd2+,M2 is a metal ion selected from the group consisting of Fe2+, Fe3+, Co2+, Co3+, Mn2+, Mn3+, V4+, V5+, Cr2+, Cr3+, Rh3+, Ru2+ and Ir3+and M1 and M2 are identical or different,A is an anion selected from the group consisting of halide, hydroxide, sulfate, carbonate, cyanide, thiocyanate, isocyanate, cyanate, carboxylate, oxalate and nitrate,X is an anion selected from the group consisting of halide, hydroxide, sulfate, carbonate, cyanide, thiocyanate, isocyanate, cyanate, carboxylate, oxalate and nitrate,L is a water-miscible ligand selected from the group consisting of alcohols, aldehydes, ketones, ethers, polyethers, esters, ureas, amides, nitriles and sulfides,a, b, c, d, g and n are selected so as to make the compound electrically neutral, ande denotes the coordination number of the ligand,e and f denote fractions or integers greater than or equal to zero,h denotes a fraction or integer greater than or equal to zero,wherein the double-metal cyanides have been applied to or incorporated into solid, inert, unfoamed supports or have been shaped to give moldings. |
