TL;DR: In this paper, the effect of the diluent using polar and nonpolar solvents in the extraction of copper(II) is discussed and the extraction constants are evaluated for different diluents.
Abstract: The liquid–liquid extraction of copper(II) from sulfate medium with di(2-ethylhexyl)phosphoric acid (D2EHPA, HL) at 25°C is studied with the following parameters: pH, concentration of the extractant, and the nature of diluent. The effect of the diluent using polar and nonpolar solvents in the extraction of copper(II) is discussed. The extracted copper(II) species were CuL2 in 1-octanol and methyl isobutyl ketone and CuL2 · 2HL in toluene, carbon tetrachloride, and cyclohexane. The extraction constants are evaluated for different diluents.

TL;DR: The history of commercial processes for zirconium/hafnium production and separation is reviewed in this paper, and a new technology is then proposed as a potential alternative for ZIRCONIA/HafNium separation in a simpler, cleaner way than achieved with current processes.
Abstract: The history of commercial processes for zirconium/hafnium production and separation is reviewed. A new technology is then proposed as a potential alternative for zirconium/hafnium separation in a simpler, cleaner way than achieved with current processes. Primary sources of zirconium always contain small amounts of hafnium that must be removed during production of zirconium metal for nuclear applications. This separation is usually carried out by a solvent extraction process, developed in the 1950s, that selectively extracts hafnium, as a thiocyanate complex, using methyl isobutyl ketone (MIBK). Environmental problems inherent to this process are the high aqueous solubility and low flash point of MIBK, and possible gaseous contaminants formation generated by the decomposition of the thiocyanic complexes in hydrochloric acid medium (H 2 S, HCN, mercaptan's formation). The present work shows how these problems could be avoided by using organophosphorous extractants that were unavailable when the MIBK process was developed.

TL;DR: Solvent-containing products for plastic miniature hobby and industrial application were analyzed for solvent constituents by capillary gas-chromatography, finding acetone and methyl isobutyl ketone were two most extensively used solvents both in terms of frequency and concentration.
Abstract: Solvent-containing products (8 paint, 29 glue and 4 thinner preparations) for plastic miniature hobby were analyzed for solvent constituents by capillary gas-chromatography. Acetone and methyl isobutyl ketone were two most extensively used solvents both in terms of frequency and concentration. Other popular solvents included ethyl alcohol and two esters of ethyl acetate and butyl acetate. In contrast, aromatics, chlorinated hydrocarbons and ethylene glycol derivatives were seldomly detected. The present findings were discussed in comparison with the observation on the materials abused for sniffing in the past, as well as constituents in the products for industrial application.
