Effect of amine structure on gallium extraction from hydrochloric acid solutions

The extractability of amine salts has been studied in a series of secondary amines-tertiary amines-quaternary ammonium salts while extracting gallium from hydrochloric acid solutions.

Description
Summary:The extractability of amine salts has been studied in a series of secondary amines-tertiary amines-quaternary ammonium salts while extracting gallium from hydrochloric acid solutions. The two- and single-parametric correlations obtained have revealed that the steric factor of the substituent attached to the nitrogen atom is not vital to the series of extractants studied. A change in the gallium extraction constant is determined by the induction effect (electronegativity) of substituents, thus the extractability of gallium with quaternary ammonium salts is the highest. Trialkyl amine was thus chosen as an extractant for the commercial applications of gallium extraction from complex acid solutions.
