Abstract (en)
[origin: DE102005057895A1] Preparation of multi-metal cyanide compound comprises reacting an aqueous solution of a metal salt (I) with an aqueous solution of a cyanometallate compound (II), optionally in the presence of an organic ligand, organic additive and/or surface active agent to give a multi-metal cyanide compound (III); and reacting (III) with a metal salt (IV), which is different from (II). Preparation of multi-metal cyanide compound comprises reacting an aqueous solution of a metal salt (I) of formula (M 1> gX n) with an aqueous solution of a cyanometallate compound (II) of formula (M 3> r[M 2>(CN) b] d), optionally in the presence of an organic ligand, organic additive and/or surface active agent to give a multi-metal cyanide compound (III) of formula (M 1> a[M 2>(CN) b] dfM 1> jX kh(H 2O)eLzP 1>); and reacting (III) with a metal salt (IV) of formula (M 4> sY 1> t), which is different from (II). M 1>a metal ion such as Zn 2+>, Fe 2+>, Fe 3+>, Co 2+>, Co 3+>, Ni 2+>, Mn 2+>, Sn 2+>, Sn 4+>, Pb 2+>, Al 3+>, Sr 2+>, Cr 3+>, Cd 2+>, Cu 2+>, La 3+>, Ce 3+>, Ce 4+>, Eu 3+>, Mg 2+>, Ti 4+>, Ag +>, Rh 2+>, Ru 2+>, Ru 3+> or Pd 2+>; M 2>a metal ion such as Fe 2+>, Fe 3+>, Co 2+>, Co 3+>, Mn 2+>, Mn 3+>, Ni 2+>, Cr 2+>, Cr 3+>, Rh 3+>, Ru 2+> or Ir 3+>; X : an anion such as halogenide, OH, sulfate, hydrogensulfate, carbonate, hydrogencarbonate, cyanide, thiocyanate, isocyanate, cyanate, carboxylate, oxalate, nitrate and/or nitrite (NO 2 ->) or uncharged species such as CO, H 2O or NO; Y 1>an anion such as halogenide, sulfate, hydrogensulfate, disulfate, sulfite, sulfonate (=RSO 3 ->, where R is 1-20C alkyl, aryl or 1-20C alkylaryl), carbonate, hydrogencarbonate, cyanide, thiocyanate, isocyanate, isothiocyanate, cyanate, carboxylate, oxalate, nitrate, nitrite, phosphate, hydrogenphosphate, dihydrogenphosphate, diphosphate, borate, tetraborate, perchlorate, tetrafluoroborate, hexafluorophosphate or tetraphenylborate; L : a ligand, mixable with water, such as alcohol, aldehyde, ketone, ether, polyether, ester, polyester, polycarbonate, urea, amide, nitrile and/or sulfide; P 1>an organic additives such as polyether, polyester, polycarbonate, polyalkyleneglycolsorbitaneester, polyalkyleneglycolglycidylether, polyacrylamide, poly(acrylamide-co-acrylic acid), polyacrylic acid, poly(acrylamide-co-maleic acid), polyacrylnitrile, polyalkylacrylate, polyalkylmethacrylate, polyvinylmethylether, polyvinylethylether, polyvinylacetate, polyvinylalcohol, poly-N-vinylpyrrolidone, poly(N-vinylpyrrolidone-co-acrylic acid), polyvinylmethylketone, poly(4-vinylphenol), poly(acrylic acid-co-styrene), oxazoline polymer, polyalkyl imine, maleic acid, maleic acid anhydride copolymer, hydroxyethylcellulose, polyacetate, ionic surfaces and surface area active compound, gallic acid or its salt, ester, amide, carbonic acid ester of polyvalent alcohols or glycoside; M 3>H or an alkali- or alkaline earth metal; M 4>alkalimetal ion or an ammonium ion (NH 4 +>) or alkylammonium ion (R 4N +>, R 3NH +>, R 2NH 2 +>, RNH 3 +> (where R is 1-20C alkyl)); and a, b, d-g, n, r, s, j, k, t : a whole or fractional number that is greater than zero (where a, b, d, g, n, j, k, r, s and t are selected such that the electro neutrality is assured); and e, f, h, z : greater than or equal to 0. Provided that M 1> and M 2> are same or different. Independent claims are included for: (1) a multi-metal cyanide compound (V) of formula (M 1> a[M 2>(CN) b] dfM 1> uX vY 1> mh(H 2O)eLzP) that is prepared from the above process; and (2) the preparation of polyetheralcoholene comprising adding an alkylene oxide to a hydrogen functionalized starting substance, where multi-metal cyanide compound is used as a catalyst. u, v, m : whole or fractional numbers that are greater than zero, where the electro neutrality is assured.
