TL;DR: In this paper, it was shown that InX n (H 2 O) 6-n 3-n (X =F, Cl, Br, I) can be formed in nonaquous media for L = dimethylformamide, dimethylsulfoxide, or tributyl phosphate and X = Cl or Br, whereas only four coordinate tetrahedral InI 4 − anion is observed in the indium iodide aqueous solution with additional HI, mainly due to the large size of the iodine atom.
Abstract: Indium(III) halide complexes have shown a remarkably varied crystal chemistry; structures containing indium in 4-8 coordination are known, whereas only coordination numbers of 4 and 6 have been reported for the complexes in solution. Insertion of water molecule into the coordination sheath readily occurs, resulting in six coordinate complexes. Various mixed halogeno/aqua complexes InX n (H 2 O) 6-n 3-n (X =F, Cl, Br, I) are observed in aqueous solution. More complicate InF n X m (H 2 O) 6-n-m 3-n-m (X=Cl, Br) species have also been identified in a recent F NMR study of indium fluoride complexes. Six coordinate InX n L 6-n 3-n species can also be formed in nonaquous media for L = dimethylformamide, dimethylsulfoxide, or tributyl phosphate and X = Cl or Br, whereas only four coordinate tetrahedral InI 4 − anion is observed in the indium iodide aqueous solution with additional HI, mainly due to the large size of the iodine atom. It is also reported in In NMR studies that four coordinate indium halide anions (InX 4 −) are obtained in extraction with solvents such as acetone, methyl isobutyl ketone, ethyl ether, isopropyl ether, n-butyl acetate, cyclohexanone, and ethyl acetoacetate from HCl, HBr, and HI solutions.

Journal ArticleDOI
TL;DR: In this paper, the authors examined the reactive extraction of propionic acid, a promising liquid-liquid extraction technique, using tri-n-octylphosphine oxide (TOPO) or dioctylamine (DOA) diluted with eight different solvents at 298.15 K to determine the most efficient mixture for the extraction processes.
Abstract: This work examines the reactive extraction of propionic acid, a promising liquid–liquid extraction technique, using tri-n-octylphosphine oxide (TOPO) or dioctylamine (DOA) diluted with eight different solvents (n-octane, methyl isobutyl ketone (MIBK), 1-octanol, ethyl methyl ketone, diisobutyl ketone, n-decane, diethyl sabecate, 1-decanol) at 298.15 K to determine the most efficient mixture for the extraction processes. A phosphorous-based extractant, TOPO, has been chosen for the extraction tests since it has low water solvency and is more ecologically agreeable than the amine-type extractants. Among the other amine extractants reported in reactive extraction studies, there is no study on propionic acid extraction using DOA in the literature. Physical extraction experiments with pure solvents were also performed to analyze the effect of TOPO and DOA on the extraction process. Distribution coefficients, loading factors, and extraction yields of the processes were determined for the explanation of the resu...
