摘要
Solvent extraction, molecular weight determination, and infrared analysis have been used to study the nature of the amine salt present in the organic phase in the extraction of sulfuric acid by tri-n-caprylamine. Tri-n-capryl-amine in the concentration range of 0.05–0.25 M extracts sulfuric acid to form either the normal sulfate or the bisulfate salt, depending on the concentration of acid in the aqueous phase. The normal sulfate is monomeric, while the bisulfate is dimeric. Characteristic infrared absorption bands, attributable to the normal sulfate and the bisulfate salt form, were observed. © 1968, Taylor & Francis Group, LLC. All rights reserved.
