Method for the synthesis of iron hexacyanoferrate

Vail, Sean; Lu, Yuhao; Lee, Jong-Jan

Title: Method for the synthesis of iron hexacyanoferrate

Abstract

A method is provided for synthesizing iron hexacyanoferrate (FeHCF). The method forms a first solution of a ferrocyanide source [A4Fe(CN)6.PH2O] material dissolved in a first solvent, where “A” is an alkali metal ion. A second solution is formed of a Fe(II) source dissolved in a second solvent. A reducing agent is added and, optionally, an alkali metal salt. The first and second solutions may be purged with an inert gas. The second solution is combined with the first solution to form a third solution in a low oxygen environment. The third solution is agitated in a low oxygen environment, and AX+1Fe2(CN)6.ZH2O is formed, where X is in the range of 0 to 1. The method isolates the AX+1Fe2(CN)6.ZH2O from the third solution, and dries the AX+1Fe2(CN)6.ZH2O under vacuum at a temperature greater than 60 degrees C.

Sodium iron(II)-hexacyanoferrate(II) battery electrode and synthesis method

Patent Lu, Yuhao; Vail, Sean Andrew

A method is provided for synthesizing sodium iron(II)-hexacyanoferrate(II). A Fe(CN)6 material is mixed with the first solution and either an anti-oxidant or a reducing agent. The Fe(CN)6 material may be either ferrocyanide ([Fe(CN)6]4−) or ferricyanide ([Fe(CN)6]3−). As a result, sodium iron(II)-hexacyanoferrate(II) (Na1+XFe[Fe(CN)6]Z.MH2O is formed, where X is less than or equal to 1, and where M is in a range between 0 and 7. In one aspect, the first solution including includes A ions, such as alkali metal ions, alkaline earth metal ions, or combinations thereof, resulting in the formation of Na1+XAYFe[Fe(CN)6]Z.MH2O, where Y is less than or equal tomore »« less

Iron catalyst for preparation of polymethylene from synthesis gas and method for producing the catalyst

Patent Sapienza, Richard S [1 Miller Ave., Shoreham, NY 11786]; Slegeir, William A [7 Florence Rd., Hampton Bays, NY 11946]

This invention relates to a process for synthesizing hydrocarbons; more particularly, the invention relates to a process for synthesizing long-chain hydrocarbons known as polymethylene from carbon monoxide and hydrogen or from carbon monoxide and water or mixtures thereof in the presence of a catalyst comprising iron and platinum or palladium or mixtures thereof which may be supported on a solid material, preferably an inorganic refractory oxide. This process may be used to convert a carbon monoxide containing gas to a product which could substitute for high density polyethylene.
