Temperature Dependence of Uranium and Vanadium Adsorption on Amidoxime‐Based Adsorbents in Natural Seawater

ChemistrySelect, 2018
Recent advances in the development of amidoxime‐based adsorbents have made it highly promising for seawater uranium extraction. However, there is a great need to understand the influence of temperature on the uranium sequestration performance of the ...

Amidoximes and Their Prodrugs

Archiv der Pharmazie, 1998
Seventeen amidoximes (2a-q) comprising aliphatic (2a-d), aromatic (2e-n), and bis compounds (2o-q) have been synthesized. In the Born test 4-chlorophenylethenecarboxamidoxime (21) was most active and inhibited the blood platelet aggregation induced by collagen with an IC50 = 3 microM.

The Reaction of Amidoximes with Chloroacetyl Chloride

Synthetic Communications, 1992
Abstract 1,2, 4-Oxadiazole and 1,2, 4-oxadiazine derivatives were obtained from the reaction of amidoximes with chioroacetyl chloride. The treatment of 3,4-disubstituted-Δ2- dihydro-1,2,A-oxadiazine-5-ones with P2S5 gave corresponding 5-thiones.

The extraction of uranium by amidoximated orlon

Talanta, 1997
The nitrile groups in polyacrylonitrile (Orlontrade mark) fabric were converted to amidoxime groups to produce an amidoximated orlon fabric. The amidoximated fabric was evaluated for its ability to extract uranium from aqueous solution with a wide range of temperature and pH values.

Adsorption of UO2+2 by polyethylene adsorbents with amidoxime, carboxyl, and amidoxime/carboxyl group

Radiation Physics and Chemistry, 2000
Abstract The polyethylene (PE) adsorbents were prepared by a radiation-induced grafting of acrylonitrile (AN), acrylic acid (AA), and the mixture of AN/AA onto PE film, and by subsequent amidoximation of cyano groups of poly-AN graft chains. With an increase of AA composition in AN/AA monomer mixture, the water uptake of the grafted polyethylene film

Reactions of amidoximes with orthoacetates

Journal of Heterocyclic Chemistry, 1993
AbstractThe reaction of two amidoximes 4 with ethyl orthoacetate in the presence of an acid catalyst gave triazine N‐oxides 7. A mechanism via a Beckmann rearrangement to a carbodiimide, followed by reaction with amidoxime and the ortho ester, is proposed.

Reactions of pentafluoropyridine with amidoximes

Journal of the Iranian Chemical Society, 2017
In this paper, site reactivity of amidoximes with pentafluoropyridine under basic conditions in dry CH3CN was investigated. The aromatic nucleophilic substitution of pentafluoropyridine with amidoximes occurs in the 4-position of the pyridine ring by the oxygen site of amidoximes and followed by reaction of other sites, depending on reaction conditions.

Metal derivatives of amidoximes V. Dialkyl- or diphenyl-silyl derivatives of amidoximes

Journal of Organometallic Chemistry, 1975
Abstract New monomeric dialkyl- or diphenyl-silylbisamidoximes and dialkyl(ethoxy)silylamidoximes have been characterised. Their infrared spectra have been interpreted and diamagnetic susceptibility of some of them has been determined.
