Solvent extraction of manganese with thenoyltrifluoracetone
Talanta, 1966The formula of the manganese-TTA complex extracted with xylene from 0.5M sulphuric acid solution containing sodium bromate is MnT(3) where HT is the enol form of thenoyltrifluoracetone, TTA. The formula of the manganese-TTA complex extracted from slightly acid solution (pH 4-5) with acetone-benzene mixture is MnT(2). The extraction constants of the MnT(

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.

Solvent Extraction: Principles and Practices ☆
2018Recent advances in analytical chemistry are characterized by great progress toward more powerful methods of separation, equaling in significance the great forward strides made in instrument methods of determination. Problems of chemical analysis almost always involve two steps; separation of the desired constituent and measurement of the amount or ...

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 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.

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.
