Application of 56602-33-6This research focused onthorium ion imprinted polymer synthesis acidity. The article conveys some information:
A new ion-imprinted polymer (IIP) was synthesized by thermal copolymerization of bis(2-methacryloxyethyl) phosphate as functional ligand and ethylene glycol dimethacrylate as crosslinker in the presence of Th4+ as a template ion. The molar ratio of the functional ligand to Th4+ was optimized to be 4 by 31P NMR titration, elemental anal., and EXAFS, which was verified by comparing the adsorption capacities and selectivities of IIPs with different composition Thorium(IV) ions were leached out using 0.1 mol L-1 EDTA disodium salt and the prepared IIP was characterized by infra-red spectroscopy, thermogravimetric anal. and Brunauer-Emmett-Teller surface area measurement. It was found that the IIP could extract Th4+ from high acidity solution The maximum adsorption capacity was as high as 33.3 mg g-1 in 1.0 mol L-1 HCl. Even in 6.0 mol L-1 HCl, its adsorption capacity was still considerable. Moreover, the IIP exhibited good selectivity towards Th4+, especially in the presence of competing ions such as La3+, Eu3+, Yb3+, UO22+, and Fe3+.((1H-Benzo[d][1,2,3]triazol-1-yl)oxy)tris(dimethylamino)phosphonium hexafluorophosphate(V)(cas: 56602-33-6Application of 56602-33-6) was used in this study.
((1H-Benzo[d][1,2,3]triazol-1-yl)oxy)tris(dimethylamino)phosphonium hexafluorophosphate(V)(cas: 56602-33-6) is used as a reagent for peptide coupling, lactonization, selective esterification, amidation of alfa amino acids without racemization and synthesis of magnolamide for antioxidative activity and catalyst for 9-acridinecaroboxamide derivative. It is also used as a precursor for the synthesis of phenyl esters of amino acids.Application of 56602-33-6
