The Solvent Extraction of Metal Chelates is a comprehensive account of the solvent extraction (liquid-liquid extraction) of metal chelate complexes. Topics covered include the composition and stability of metal chelates; analytical applications of the solvent extraction of metal chelates; and selective extraction procedures for metals. A theoretical treatment of the solvent extraction of metal chelates is also given. This book is comprised of six chapters and begins with an overview of solvent extraction and how it can be used to solve important theoretical problems concerning the composition and stability of soluble and insoluble metal complexes. The next chapter examines the composition and stability of metal chelates based on the assumption that only uncharged complexes are dissolved and extracted by the organic solvents. A theory of the solvent extraction of metal chelates is then described, paying particular attention to a variety of factors that influence the extraction of metal chelates, including acidity, solubility and instability of the metal chelate, and organic solvent. Some analytical applications of the solvent extraction of metal chelates are also considered. The last two chapters deal with systems and selective extraction procedures for metals. This monograph will be of particular value to inorganic and analytical chemists.

Recent Advances in Liquid-liquid Extraction focuses on the applications of liquid extraction. The selection first discusses solvent extraction. Concerns include organic and inorganic separations, mass transfer process, solvent extraction economics, and coalescence in liquid-liquid systems. The book focuses on the chemistry of solvent extraction. Extraction by acidic organophosphorus compounds; extraction by phosphorus-bonded oxygen-donor solvents; extraction by high-molecular weight amines; and synergistic extraction are elaborated. The book also focuses on industrial organic processes; industrial contacting equipment; response characteristics and control of extraction processes; and calculation of contactors with longitudinal mixing. The selection presents the study of longitudinal mixing in liquid-liquid contactors. Rotating disc contactors, packed columns, vibrating plate extractors, and Oldshue-Rushton columns are described. The text also discusses heat transfer by direct liquid-liquid contact and the coalescence of liquid droplets and liquid dispersion. The selection is a vital source of data for readers interested in liquid extraction.

The solvent extraction properties of 1,1,1-trifluoro-2,4-pentanedione (H(tfa)), 1,1,1,5,5,5-hexafluoro-2,4-pentanedione (H(hfa)), 1,1,1,2,2,6,6,6-octafluoro-3,5-hexanedione (H(ofhd)), 1,1,1,2,2,3,3,7,7,7-decafluoro-4,6-heptanedione (H(dfhd)), and 1,1,1,2,2,3,3-heptafluoro-7,7-dimethyl-4,6-octanedione (H(fod)) are described. Distribution ratio-pH curves or percent extracted-pH curves are presented for the extraction of copper, iron, beryllium, cobalt, zinc or other metal ions employing chloroform or benzene solutions of each ligand, and for the effective extraction of divalent and trivalent metals with butanol-H(tfa). Marked enhancement of extraction efficiency of divalent metal ions into chloroform or benzene via isobutylamine adduct formation is also described for most systems. The effect of increasing fluorocarbon chain length resulting in increasing ability to extract the divalent metals zinc and cobalt into chloroform or benzene without the aid of adduct formation is discussed, and extraction systems with the optimum ligand, H(dfhd), are characterized. Syntheses of H(dfhd), H(ofhd), and other ligands are reported, and the physical properties of these and various other fluorine-containing beta-diketones and certain toxicity studies are reviewed. Preliminary work on the direct reaction of ligands with metals in hydrocarbons is presented. (Author).
