Efficient Synthesis of Bis(1,5,3-dithiazepanes).Sorption of Palladium(II) from Nitric Acid Solutions

摘要

Bis(1,5,3-dithiazepanes) have been synthesized via cyclocondensation of aliphatic alpha,omega-diamines and hydrazine with formaldehyde and ethane-1,2-dithiol. Palladium(II) sorption with bis(1,5,3-dithiazepanes) from nitric acid solutions has been studied via a static method. Bis(1,5,3-dithiazepanes) efficiently extract palladium(II) from 0.1-4 mol/L nitric acid solutions at room temperature.
