Synthesis, characterization and ion-exchanging properties of novel ion-exchange resin-II

摘要

The polyamine (PA) was prepared by condensation of Xylidine dichloride and ethylene diamine. The PA was then treated with cyanuric chloride at 0°C-5°C and the pH is adjusted to 7.8 with NaHCO3. The resultant polyamine cynurate (PAC) was than condensed with 4-amino-1-naphthalene sulfonic acid in conc. NaOH (pH 9-10) at room temperature for 2 hrs. The resultant polymer is designated as 4,4'-((6-((4-ethylbenzyl)(2-(methylamino)ethyl)amino) -1,3,5-triazine-2,4-diyl)bis(azanediyl))bis(naphthalene-1-sulfonic acid) was characterized by elemental analysis, IR spectral studies, and Thermogravimetry.
