Efficient masking of corrosion and fission products such as Ni(II) and Pd(II) in the presence of the minor actinide Am(III) using hydrophilic anionic or cationic bis-triazines

Water soluble anionic and cationic bis-triazine ligands are able to suppress (mask) the extraction of corrosion and fission products such as Ni(II) and Pd(II) that are found in PUREX raffinates. Thus it is possible to separate these elements from the minor actinide Am(III). Although some masking agents have previously been developed that retard the extraction of Pd(II), this is the first time a masking agent has been developed for Ni(II).

Synthesis, structure, and properties of phosphorus-containing bis(amidrazones)

Previously unknown ethenylphosphonic derivatives of bis(amidrazones) were prepared. According to spectroscopic data and quantum-chemical calculations, these compounds exist as phosphonium salts of a symmetrical linear structure with trans arrangement of the amidrazone fragments. In alkaline solutions, they are unstable and decompose to form triarylphosphine oxides. In contrast to ordinary amidrazones, their phosphorus-containing derivatives do not tend to form complexes with transition metals. Nauka/Interperiodica 2006.

Process for the preparation of 5,5'-bi-1H-Tetrazolediammonium salts using hydrazine hydrate and dicyan as starting materials

A process for preparing 5,5'-bi-lH-tetrazolediammonium salts (BHT · 2NH3) maintaining a high yield through oxaldiimidic acid dihydrazide (OAH) from the starting materials which are cheaply available and are easy to handle. The 5,5'-bi-1H-tetrazolediammonium salts (BHT · 2NH3) are prepared by dissolving the oxaldiimidic acid dihydrazide (OAH) obtained by the reaction of hydrated hydrazide with dicyan in an aqueous solution of a weakly acidic compound such as acetic acid, dropwisely adding an aqueous solution of sodium nitrite thereto form an azide thereof and to effect the cyclization reaction by heating, adding an aqueous solution of sodium hydroxide to the reaction product to convert it into a 5,5'-bi-1H-tetrazolediammonium salt (BHT · 2Na), reacting it with an aqueous solution of ammonium chloride, and recovering the formed ammonium salt as sparingly soluble crystals.
