In a document, author is McAlister, D. R., introduce the new discover, SDS of cas: 707-07-3.
Extraction of Selected Metal Ions with Mixtures of N,N,N’,N’-tetra-n-octyldiglycolamide and 4,4 ‘(5 ‘)-di-t-butylcyclohexano 18-crown-6
Previous work has shown that solvent extraction (SX) and extraction chromatography (EXC) systems containing mixtures of extractants can be utilized to impart selectivity and improved physical characteristics that were not achievable with a single extractant. In an effort to discover EXC materials with unique selectivity and improved physical properties, we studied the extraction of selected metal ions from nitric acid and hydrochloric acid by EXC resins prepared from mixtures of N,N,N’,N’-tetra-n-octyldiglycolamide (TODGA) and 4,4 ‘(5 ‘)-di-t-butylcyclohexano 18-crown-6 (dtBCH18C6). Except for enhanced extraction of Ra and Ba from dilute HNO3, the EXC resins essentially exhibited the metal ion extraction properties expected from materials prepared with the individual extractants. The origin of the Ra/Ba enhancement was studied by solvent extraction variation studies in 1-octanol and n-dodecane and on extraction chromatography resins, indicating that the enhancement may not be a true synergistic interaction between the extractants, but a phase modification by the TODGA related to the co-extraction of HNO3 and water. Additionally, the influence of alkyl substituents on the DGA extractant and potential applications of the mixed extractant system in analytical chemistry and nuclear medicine were explored with extraction chromatography resins prepared from the extractant mixtures.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 707-07-3 is helpful to your research. SDS of cas: 707-07-3.
