摘要：
Phase equilibria in the water-alkyldimethylammonium chloride (catamine AB)-nitric acid/nitrate biphasic systems were studied. The effect of salting-out agents on the phase separation in the systems was considered. The possibility of using the water-catamine AB-NH4NO3 system for liquid extraction was shown using the extraction of metal chloride acidocomplexes from HCl or H2SO4 solutions in this system as an example.
