Solvent extraction of niobium and tantalum—VII
Journal of Inorganic and Nuclear Chemistry, 1966Abstract Studies of the extraction of niobium and tantalum oxalato solutions with tri-n-octylamine (TOA), tri-n-decylamine (TDA) and tri-n-dodecylamine (TDDA) in carbon tetrachloride have been carried out. The metal/amine ratio was determined in the organic phase and an identical behaviour was observed for all the three extractants.

INVESTIGATION OF SOLVENT LOSSES IN THE SOLVENT EXTRACTION OF BORON
Solvent Extraction and Ion Exchange, 1995ABSTRACT Solubility, adsorption onto mineral particles and entrainment of 2-chloro-4-(1,1,3,3-tetramethy1-buty1)-6-methylol-phenol (CTMP) in aqueous slurry phase are considered here. The results show that, the solubility at equilibrium increased sharply with pH, but remained at only 16 parts per million (ppm) at pH 9.

Some solvent effects on the solvent extraction of 8-quinolinol
Talanta, 1967The distribution constants of 8-quinolinol between water and a series of substituted aliphatic hydrocarbons, at 25 degrees , are reported. The results are discussed in terms of dielectric constant and solubility parameter of the solvents. For 8-quinolinol, and possibly for its chelates, bromochloromethane, dibromomethane and chloroform seem to be about

Solvent Extraction, Leaching and Supercritical Extraction
2006Solvent extraction, or liquid-liquid extraction, is the separation of impurities (solutes) from a liquid solution by contacting it with another immiscible liquid (solvent) in which the impurities have a high affinity. The high affinity driving the separation can be either physical solubility differences or a chemical reaction.

Alternate solvent for soybean oil extraction based on extractability and membrane solvent recovery
Environmental Science and Pollution ResearchEthyl acetate, acetone, 2-propanol, 1-propanol, and ethanol were screened among the class 3 category solvents as an alternative to hexane based on operational and occupational safety and bio-renewability potential. All five solvents exhibited higher extractability (22.3 to 23.2%) than hexane (21.5%) with soybean flour.
