Efficient synthesis of bis(1,5,3-dithiazepanes). Sorption of palladium(II) from nitric acid solutions

Аннотация

Bis(1,5,3-dithiazepanes) have been synthesized via cyclocondensation of aliphatic α,ω-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.
