In this work, four triazole-based poly(ether-pyridine)s polymers were synthesized and used as an adsorbent for the removal of phenolic compounds from aqueous solutions For this purpose, new fluoromonomers containing 1,2,3-triazole units were prepared by the Cu(I)-catalyzed 1,3-dipolar cycloaddition reaction and then used for the elaboration of novel poly(ether-pyridine-triazole)s (PEPTs) by direct polycondensation with isosorbide and bisphenol A. Chem. structure of fluorinated pyridinic monomers as well as resulting polymers was confirmed by 1H and 19F NMR spectroscopic methods. The thermal behavior of the obtained PEPTs was characterized using differential scanning calorimetry and thermogravimetric anal. Results of sorption showed that polymers can be effectively used as a sorbent for the removal of polar organic pollutants. The isosorbide-based poly(ether-pyridine-triazole) which contains hydrophilic hydroxyl groups as pendants chains (P4) exhibited the highest sorption efficiencies (78%-100% after 1 h). In order to explain the results an adsorption mechanism mainly based on 蟺-蟺 interactions and hydrogen bonding with the pendent groups is proposed. This study involved multiple reactions and reactants, such as 2,3,4,5,6-Perfluoropyridine (cas: 700-16-3SDS of cas: 700-16-3).
2,3,4,5,6-Perfluoropyridine (cas: 700-16-3) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of 鈭?8.7 脳 10鈭? cm3路mol鈭?.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ路mol鈭? in the liquid phase and 140.4 kJ路mol鈭? in the gas phase. Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.SDS of cas: 700-16-3
