    Abstract: Producing alkoxylates involves contacting one or more alkylene oxides selected from ethylene, propylene, butylene, pentylene and decene oxides with a starter compound in the presence of a binary metal cyanide compound (I) and performing the reaction at 130-155 degreesC. Producing alkoxylates involves contacting one or more alkylene oxides selected from ethylene, propylene, butylene, pentylene and decene oxides with a starter compound in the presence of a binary metal cyanide compound M1a(M2(CN)b(A)c)d.fM1gXn.h(H2O).eL.kP' (I) and performing the reaction at 130-155 degreesC. M1 = Zn2+, Fe2+, Fe3+, Co3+, Ni2+, Mn2+, Co2+, Sn2+, Pb2+, Mo4+, Mo6+, Al3+, V4+, V5+, Sr2+, W4+, W6+, Cr2+, Cr3+, Cd2+, Hg2+, Pd2+, Pt2+, V2+, Mg2+, Ca2+, Ba2+, Cu2+, La3+, Ce3+, Ce4+, Eu3+, Ti3+, Ti4+, Ag+, Rh2+, Rh3+, Ru2+ or Ru3+; M2 = Fe2+, Fe3+, Co3+, Mn2+, Mn3+, V4+, V5+, Cr2+, Cr3+, Rh3+, Ru2+ or Ir3+; A, X = halide, hydroxide, sulfate, carbonate, cyanide, thiocyanate, isocyanate, cyanate, carboxylate, oxalate, nitrate, nitrosyl, bisulfate, phosphate, (di)hydrogen phosphate or bicarbonate; L = a water-soluble alcohol, aldehyde, ketone, ether, polyether, ester, polyester, polycarbonate, urea, amide, amine, pyridine, nitrile, sulfide, phosphide, phosphite, phosphine, phosphonate or phosphate ligand; k, e, f, h = 0 or more; P' = an organic additive; and a, b, c, d, g, n = numbers so that (I) is electrically neutral and c can be zero. An Independent claim is also included for an alkoxylate produced by the novel method.

    Abstract: The invention relates to a method for producing N-phosphonomethylglycine by reacting a hexahydrotriazine compound with a triacyle phosphate in an organi c solvent and the saponification of the phosphono compound which is obtained after previous extraction into an aqueous phase, and separation of the organ ic phase. According to the invention, said method prevents decomposition of the organic solvent during saponification.
