SELECTIVE TRANSPORT AND EXTRACTION OF ALKALI METAL CATIONS (Na & K ) THROUGH CHLOROFORM LIQUID MEMBRANE BY DIETHYLENE GLYCOL MONOBUTYL ETHER AND DIETHYLENE GLYCOL DIBUTYL ETHER
Authors: not saved
Abstract:
A liquid membrane containing diethylene glycol monobutyl ether (2) shows specificity for K ion in transport while diethylene glycol dibutyl ether (1) was selective for Na over K . As an extractant, ligand 2 exhibited pronounced extraction selectivity for K over Na in comparison with ligand 1

The mutagenic potential of diethylene glycol monobutyl ether (diEGBE) was examined with a Tier I battery of in vitro assays followed by a Tier II in vivo Drosophila sex-linked recessive lethal assay. The in vitro battery consisted of: the Salmonella mutagenicity test, the L5178Y mouse lymphoma test, a cytogenetics assay using Chinese hamster ovary cells and the unscheduled DNA synthesis (UDS) a...

Background: In contrast to DNA-mediated transposable elements (TEs), retrotransposons, particularly non-long terminal repeat retrotransposons (non-LTRs), are generally considered to have a much lower propensity towards horizontal transfer. Detailed studies on site-specific nonLTR families have demonstrated strict vertical transmission. More studies are needed with nonsite-specific non-LTR famil...

Thedensity(ρ) and speed of sound (u)of the binarymixture (diethylene glycol monoethyl ether (carbitol) + propylene glycol (PG)) have been reported at T= (288.15, 298.15, 308.15 and 318.15) K. The excess molar volume ( ) and isentropic compressibility deviation (Δκs) were calculated using the measured data. The obtained values of ( ) and (Δκs) are negative and positive,...

The kinetics of esterification of 7-theophyllineacetic acid with diethylene glycol monomethyl ether in the presence of dicyclohexylcarbodiimide and 4-dimethylaminopyridine as catalyst was studied. According to the known mechanism, besides the main process, the side-reaction of intramolecular rearrangement with formation of pharmacologically active N-acylurea occurs. The course of the main and t...
