1H and 13C NMR chem. shifts for N-acetylaziridine, N-acetyl-2-methylaziridine and from some α-monosubstituted-N-acetyl-2,2-dimethylaziridines were recorded. The carbonyl carbon shieldings were compared to the corresponding shieldings of mono-substituted propanones, Me acetates and N,N-diethylacetamides, and were also empirically estimated by Tanaka et al.’s equation. A non-additivity of substituent chem. shifts was observed for the α-methylene carbon, but both the α-methylene carbon as the proton chem. shifts, correlate well with the same nuclei shifts of the three series of monosubstituted carbonyl compounds The Me group’s additivity effects on the remaining carbons are briefly discussed.

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.

Manohar, Smitha; Sharma, J. N.; Shah, B. V.; Wattal, P. K. published the artcile< Process development for bulk separation of trivalent actinides and lanthanides from radioactive high-level liquid waste>, Recommanded Product: 2-Chloro-N,N-diisobutylacetamide, the main research area is actinide lanthanide solvent extraction radioactive liquid waste.

Inhouse R and D studies resulted in the development of processes for the bulk separation of trivalent actinides and lanthanides from radioactive high-level liquid waste. Synthesis of solvents, namely, n-octyl (phenyl)-N,N-di-iso-Bu carbamoyl Me phosphine oxide and diglycolamide-based tetra (2-ethylhexyl) diglycolamide (TEHDGA), at the required purity was carried out, and a suitable process for their resp. use in actual application was developed. Inactive scale engineering runs comprised of simultaneous extraction and stripping operations were carried out to establish the process on an engineering scale, including reuse of the solvent system. The composition of surrogate high-level waste (HLW) used at engineering-scale studies corresponds to 1st-cycle raffinate from reprocessing of long-cooled pressurized D2O reactor fuel with a burnup of 6500 MWd/ton. Since trivalent lanthanides and actinides exhibits similar extraction behavior at higher acidity, Ce and La were only used in making surrogate HLW to represent all the trivalent lanthanides and actinides. Indigenously developed mixer-settlers using a passive system of mixing were used for these runs. Over a period of ∼10 h, ∼ 300 e of surrogate HLW solutions were contacted with solvent. The results of such repeated trials showed near-total removal of Ce and La (>99.8% and 97%, resp.) at aqueous-to-organic ratio of 2.5:1 for a TEHDGA system. As the distribution coefficient values for trivalent actinide (241Am) are significantly higher than those for trivalent lanthanides for both of the solvent systems under consideration, it can be inferred that separation of trivalent actinides along with lanthanides could be feasible using these solvent systems.

The structure and complexing properties in ion-selective PVC membrane electrodes>, Computed Properties of 5326-82-9, the main research area is calixarene lower rim amide substituted preparation; ion selective PVC membrane electrode calixarenamide.

Di- and tetraamide tert-butylcalix[4]arenes were synthesized and described. Their ionophoric properties were studied in liquid membrane ion-selective electrodes. The correlation between the chem. structure (conformation in solution determined by 1H NMR) and potentiometric ion-selectivity and complex formation constant have been studied. The PVC membrane electrodes based on tetraamides I (R = n-Bu2N, morpholino, 1-piperidinyl, CH3(CH2)6MeN) show high sodium selectivity and are stable and long lasting. Disubstituted amides II (R = Et2N, n-Pr2N, i-Pr2N, n-Bu2N, i-Bu2N, morpholino, 1-piperidinyl) are selective for larger and more lipophilic ions, e.g., guanidinium ion. The crystal structure of the diamide II (R = n-Bu2N) was determined by single crystal X-ray anal. Crystals of II (R = n-Bu2N) are triclinic, space group P-1, with: a = 16,669(8), b = 17.795(10), c = 20.984(8) Å, α = 91.08(4)°, γ = 90.73(4)° and Z = 4. Ionophore II (R = n-Bu2N) possesses a distorted cone conformation and is substituted at the proximal phenol rings.

Pant, Amar D.; Ruhela, R.; Limje, C.; Anil Kumar, S.; Singh, A. K.; Kumar, Suja A.; Sugandhi, S.; Kain, V.; Tomar, B. S. published the artcile< Evaluation of BenzoDODA grafted polymeric resin for rapid and reliable assaying of plutonium in sediment samples>, Category: amides-buliding-blocks, the main research area is plutonium BenzoDODA grafted polymeric resin sediment pollution; Alpha spectrometry; BenzoDODA grafted resin; Extraction chromatography; Plutonium; SPEC; Sediments.

The paper reports a new rapid radioanal. procedure for the determination of plutonium (Pu) in sediments by solid phase extraction chromatog. (SPEC) using Bis-(2-ethylhexyl) carbamoyl methoxy phenoxy-bis-(2-ethylhexyl) grafted resin, abbreviated as Benzodioxodiamide (BenzoDODA) grafted resin. The resin was synthesized and evaluated for its sorption behavior towards Pu in batch and column mode to determine its efficacy for selective recovery of Pu from sediment samples. The anal. procedure was based on the radiochem. separation of samples by acid digestion, followed by preconcentration of actinides by co-precipitation with Fe(OH)3 and finally selective recovery of Pu by SPEC using a column filled with BenzoDODA grafted resin. Pu was then radiometrically assayed by preparing alpha disk sources with electro-deposition followed by alpha spectrometry. The method was further validated with IAEA reference materials. This method gives reliable and reproducible results for the activity concentration of Pu in sediment samples within 24 h.

Synthesis and structures of [UO2(NO3)2(PhSOCH2CONiBu2)] and [Ce(NO3)3(PhSOCH2CONBu2)2]>, Electric Literature of 5326-82-9, the main research area is carbamoylmethylsulfoxide preparation complexation cerium uranyl; cerium carbamoylmethylsulfoxide complex preparation; uranyl carbamoylmethylsulfoxide complex preparation; crystal structure cerium uranyl carbamoylmethylsulfoxide complex; extraction actinide carbamoylmethylsulfoxide.

The bifunctional carbamoyl Me sulfoxide ligands, PhCH2SOCH2CONHPh (L1), PhCH2SOCH2CONHCH2Ph (L2), PhSOCH2CONiPr2 (L3), PhSOCH2CONBu2 (L4), PhSOCH2CONiBu2 (L5) and PhSOCH2CON(C8H17)2 (L6) were synthesized and characterized by spectroscopic methods. The selected coordination chem. of L1, L3, L4 and L5 with [UO2(NO3)2] and [Ce(NO3)3] was evaluated. The structures of [UO2(NO3)2(PhSOCH2CONiBu2)] (10) and [Ce(NO3)3(PhSOCH2CONBu2)2] (12) were determined by single crystal x-ray diffraction methods. Preliminary extraction studies of ligand L6 with U(VI), Pu(IV) and Am(III) in tracer level showed an appreciable extraction for U(VI) and Pu(IV) in up to 10 M HNO3 but not for Am(III). Thermal studies on compounds [UO2(NO3)2( PhSOCH2CONiPr2)] (8) and 10 in air revealed that the ligands can be destroyed completely on incineration. The electron spray mass spectra of compounds 8 and 10 in acetone show that extensive ligand distribution reactions occur in solution to give a mixture of products with ligand to metal ratios of 1:1 and 2:1. However, 10 retains its solid state structure in CH2Cl2.

Guo, Zhijun; Zhang, Weiguang; Niu, Yanning; Tan, Minyu published the artcile< Solvent extraction and separation of thorium(IV) and uranium(VI) by an ether-amide type tripodand>, Synthetic Route of 5326-82-9, the main research area is solvent thorium uranium ether amide tripodand picrate fuel reprocessing.

1,1,1-Tris(N,N-diisobutylcarbamoyl-methylene-oxymethyl)propane (L) was prepared and characterized by using IR, 1H NMR and pos.-ion FAB mass spectra. The extraction of Th4+ and UO22+ with L was studied as a function of concentration of free extractant in an organic phase and of picrate in an aqueous phase from a picrate-nitrate medium at 293 ± 1 K, in view of nuclear fuel reprocessing. The extractability of L for Th4+ is larger than that for UO22+. Both extraction % of Th4+ and UO22+ decreased with an increase in the concentration of HNO3. The mechanism of extraction of Th4+ with L was proposed. The composition of extracted species of L with Th4+ in the organic phase is ThL(Pic)2(NO3)2. The results of extraction of trace 234Th4+ with L from the picrate-nitrate medium containing UO22- (the initial concentration of UO22+, CUO22+0 = 1.23 × 10-4 mol/dm3 (M)) agreed well with those from the extraction of single component solutions The tripodand is useful in separation of Th4+ and UO22+ from each other in picrate-nitrate media with a relatively high separation factor.

New lipophilic diamide compounds were synthesized and tested as ionophores for Li in poly(vinyl chloride) (PVC) membrane electrodes, including compounds with pyridine, furan, dioxanonane, and polyether backbones with different lipophilic diamide groups. The new ionophores were compared with previously reported ionophores under similar measurement conditions with the same plasticizer, tris(2-ethylhexyl) phosphate, in all membranes. Fixed interference and matched potential methods were used to determine relative selectivity coefficients for all the electrodes. The highest selectivity for Li relative to Na was obtained with N,N-dicyclohexyl-N’,N’-diisobutyl-cis-cyclohexane-1,2-dicarboxamide (140:1) and the 14-crown-4 ether, 3-dodecyl-3-methyl-1,5,8,12-tetraoxacyclotetradecane (125:1) when using NPOE (o-nitrophenyl octyl ether) plasticizer. The latter exhibited faster response at low Li concentrations It exhibited consistently high selectivity using different measurement methods and was stable for 5 mo.
