DOUBLE METALLOCIDE CATALYST, METHOD FOR PREPARATION THEREOF, AND POLYETHER-POLYOL PRODUCTION PROCESS Russian patent published in 2004 - IPC

FIELD: catalyst preparation methods.

SUBSTANCE: invention provides double metallocide catalyst containing (i) one or more double metallocide compounds of formula: M_x[M'_x'(CN)_y]₂ wherein M represents metal selected from group including Zn(II), Fe(II), Ni(II), Mn(II), Co(II), Sn(II), Pb(II), Fe(III), Mo(IV), Mo(VI), Al(III), V(V), V(IV), Sr(II), W(IV), W(VI), Cu(II) and Cr(III); M represents metal selected from group including Fe(II), Fe(III), Co(II), Co(III), Cr(II), Cr(III), Mn(II), Mn(III), Ir(III), Ni(II), Rh(III), Ru(II), V(IV), and V(V); x, x', y and z each are integers selected so that double metallocide compound exhibits electric neutrality; (ii) one or more organic complex ligands other than (iii); and (iii) one or more phospholipids or amino acid derivatives, which can be used to prepare polyether-polyols via polyaddition of alkylene oxides to starting compounds with active hydrogen atoms. Catalyst preparation procedure of is likewise provided.

EFFECT: enlarged assortment of high-activity double metallocide catalysts.
