Anion-exchange behavior of Zr, Hf, and Th in nitric acid was investigated to determine suitable exptl. conditions for the experiment of element 104, rutherfordium (Rf) and to obtain comparative data for discussion of nitrate complexes of Rf. Anion-exchange reactions in a Adogen 464/HNO3 system was found to reach equilibrium within 60 s, suggesting that the reaction system is suitable for the experiment of 261Rf having a half-life of 68 s. We also studied the electronic states of Zr, Hf, and Th nitrate complexes by quantum chem. calculations The calculation results support the exptl. results that Th4+ forms stable anionic complexes such as [Th(NO3)6]2- with a large coordination number of 12, while Zr4+ and Hf4+ do not. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Quality Control of N-Methyl-N,N-dioctyloctan-1-aminium chloride).
N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Quality Control of N-Methyl-N,N-dioctyloctan-1-aminium chloride
