Sharma, Shikha; Ghosh, Sunil K.; Anitha, M.; Sharma, Joti N. published the artcile< α-Dialkylamino N,N-diisobutylacetamides: a new class of anion exchanger with intramolecular buffering properties>, Reference of 5326-82-9, the main research area is molybdenum dialkylamino diisobutylacetamide anion exchanger intramol buffering.
A new class of ammonium based anion exchangers embedded with a terminal amide group, viz. α-dialkylamino N,N-diisobutylacetamides was designed, synthesized and tested for their ability to extract oxometalate anions from HNO3 medium. As a representative example, the molybdate anion was chosen for the present studies and its extraction behavior was compared with routinely used anion exchangers like Alamine 336, Aliquat 336 and Primene JMT having no amide functionality. A higher %E value for molybdate was observed with α-dialkylamino N,N-diisobutylacetamides compared to Alamine 336, Aliquat 336 and Primene JMT, from the same HNO3 acidity. The presence of amide group in the ligand is the key to the success of extraction from a relatively higher concentration of HNO3 medium. The amide group in the extractant leads to extra acidity through the intramol. buffering effect thus enabling the ligand to extract the molybdate anion at higher acidities. Stoichiometry of the ion pair formed during extraction was ascertained by the slope anal. method. The composition of the complex is (LH)2MoO4·HNO3. FTIR and NMR of the loaded extractant indicated that MoO42- is associated with the ammonium site while binding of HNO3 occurred at the amide group.
