Ethylene glycol iron complex

When labeled potassium cyanide reacted with the complex in an aqueous methanol solution, the bromide was rapidly replaced and the labeled cyanide ion entered slowly into the coordination complex. When the reaction was conducted at higher temperatures in ethylene glycol dimethyl ether as the solvent, the label was distributed among the benzyl isonitrile, benzyl formamide, and the polymer resulting from benzyl isonitrile and the iron isonitrile complexes. 

This paper describes the isomorphous substitution of aluminium by iron in the MFI type zeolite by direct synthesis in presence of oxalate or phosphate iron complexes, starting from a system containing TPABr and ethylene glycol (EG). The effect of Si/Al, Si/Fe, TPABr/Si and EG/Si ratios was investigated in order to understand the influence of these parameters on the nature of the products as well as their properties. 

From conductivity measurements it may be assumed that in dilute methanolic and formamide solutions of iron(II) chloride all of the coordination sites of the iron are occupied by solvent molecules, whereas in ethylene glycol, dimethylformamide and pyridine the chloride ion also is to be found in the inner coordination sphere. If it is assumed that the equilibria prevailing in the solution are also frozen in during the rapid freezing of the solutions, and that new complex ions are not formed during... 

All-weather ethylene glycol-type solutions that automobile radiators require complex mixtures of additives, including corrosion inhibitors, stabilizers, and buffering agents. Without proper commercial inhibition, a 40 percent glycol solution at 70°C would corrode iron and steel at 250 to 500 jim/y, while also attacking the copper, brass, solder, and/or aluminum components at 25 to 50 pimly.
