Sivey, John D.; Roberts, A. Lynn published the artcile< Abiotic Reduction Reactions of Dichloroacetamide Safeners: Transformations of ""Inert"" Agrochemical Constituents>, Safety of 2-Chloro-N,N-diisobutylacetamide, the main research area is abiotic reduction reaction modeling dichloroacetamide safener transformation.

Safeners are so-called “”inert”” constituents of herbicide formulations added to protect crops from the toxic effects of herbicides. We examined the reactivity of three dichloroacetamide safeners and 12 structural analogs [all neutral compounds of the form Cl2CXC(=O)NRR’; X = H, Cl; R-groups include alkyl, branched alkyl, n-allyl, and cyclic moieties] in one homogeneous and two heterogeneous reductant systems: solutions of Cr(H2O)62+, suspensions of FeII-amended goethite, and suspensions of FeII-amended hematite. Analyses of reaction products indicate each safener can undergo stepwise hydrogenolysis (replacement of chlorine by hydrogen) in each system at near-neutral pH. The first hydrogenolysis step generates compounds similar (in one case, identical) to herbicide active ingredients. Rates of product formation and (when reactions were sufficiently fast) parent loss were quantified; reaction rates in heterogeneous systems spanned 2 orders of magnitude and were strongly influenced by R-group structure. The length of n-alkyl R-groups exerted opposite effects on hydrogenolysis rates in homogeneous vs. heterogeneous systems: as R-group size increased, reduction rates in heterogeneous systems increased, whereas reduction rates in the homogeneous system decreased. Branched alkyl R-groups decreased hydrogenolysis rates relative to their straight-chain homologs in both homogeneous and heterogeneous systems. Reaction rates in heterogeneous systems can be described via polyparameter linear free energy relationships employing mol. parameters likely to influence dichloroacetamide adsorption. The propensity of dichloroacetamide safeners to undergo reductive transformations into herbicide-like products challenges their classification as “”inert”” agrochem. ingredients.

Sharma, Shikha; Ghosh, Sunil K.; Sharma, Joti N. published the artcile< Dialkylmethyl-2-(N,N-diisobutyl)acetamidoammonium iodide as a ruthenium selective ligand from nitric acid medium>, Formula: C10H20ClNO, the main research area is dialkylmethyldiisobutylacetamidoammonium iodide ruthenium ligand nitrate; Alkylammonium acetamides; Iodide ion; Ruthenium; Separation; Solvent extraction.

A new class of quaternary ammonium iodide based ligands with 2-(N,N-diisobutyl)acetamide as an alkyl appendage were designed, synthesized and tested for their ability to extract ruthenium selectively from nitric acid medium. The 2-(N,N-diisobutyl)acetamido ammonium iodide with two Pr and a Me substituents showed best results for the recovery of ruthenium. The optimized concentration of the solvent was 0.2 M in 30% isodecyl alc./n-dodecane. The stoichiometry of the complex was ascertained by slope anal. method and was 1:1 with respect to ligand L+I- and Ru(NO)(NO3)3. Ruthenium formed an adduct of structure LRu(NO)(NO3)3I in the extraction medium. Iodide ion played an important role in the formation of the stable and extractable complex of ruthenium. No extraction was observed when iodide was replaced by nitrate anion in the ligand. The ligand also showed good selectivity for ruthenium in the presence of other metal ions commonly found in nitric acid solutions of nuclear waste.

An improved procedure for the preparation of enamine N-oxides involving aminolysis of epoxides, chlorination, N-oxidation, and dehydrochlorination is described. Although isolated β-chloroamine N-oxides are prone to rearrangements when isolated, these side reactions can be slowed by the presence of stabilizing organic acids. The scope and limitations of this strategy are discussed.

Ruhela, R.; Panja, S.; Singh, A. K.; Dhami, P. S.; Gandhi, P. M. published the artcile< BenzoDODA grafted polymeric resin-Plutonium selective solid sorbent>, Recommanded Product: 2-Chloro-N,N-diisobutylacetamide, the main research area is wastewater treatment sorption plutonium polymeric resin; BenzoDODA SDVB resin; Plutonium; Selective; Separation; Sorption.

A new ligand grafted polymeric resin (BenzoDODA SDVB) was synthesized by covalently attaching plutonium selective ligand (BenzoDODA) on to styrene divinyl benzene (SDVB) polymer matrix. BenzoDODA SDVB resin was evaluated for separation and recovery of plutonium(IV) from nitric acid medium. Sorption of Pu(IV) was found to decrease with the increase in nitric acid concentration, with very small sorption above 7.0 M HNO3. Sorption kinetics was fast enough to achieve the equilibrium within 60 min of contact where the kinetic data fitted well to pseudo-second-order model. Sorption isotherm data fitted well to Langmuir model suggesting chem. interaction between the BenzoDODA moiety and plutonium(IV) ions. Sorption studies with some of representative radionuclides of high level waste showed that BenzoDODA SDVB is selective and therefore could be a promising solid sorbent for separation and recovery of plutonium. Further, the theor. calculations done on BenzoDODA SDVB resin suggested Pu(NO3)4·BenzoDODA (1:1) sorbed complex conformed to generally observed square antiprism geometry of the plutonium complexes, with contributions from oxygen atoms of four nitrate ions as well as from four oxygen atoms present in BenzoDODA (two phenolic ether oxygen atoms and two carbonyl oxygen atoms of amidic moiety).

Sivaramakrishna, Mallampalli; Raut, Dhaval R.; Nayak, Shashikant; Nayak, Sandip K.; Mohapatra, Prasanta K. published the artcile< Unusual selective extraction of Pu4+ by some novel diamide ligands in a room temperature ionic liquid>, Product Details of C10H20ClNO, the main research area is plutonium selective extraction diamide ligand ionic liquid uranyl ion.

Extraction of Pu4+ was carried out from nitric acid feeds employing ionic liquid solutions of four novel diamide ligands containing an aromatic bridging group. The ligands with iso-Bu, Bu, n-octyl and 2-ethylhexyl groups were termed as LI, LII, LIII, and LIV, resp. and showed significantly higher extraction of the tetravalent plutonium ion as compared to the hexavalent uranyl ion. Using 0.05 M ligands, the extraction of Pu4+ was in the range of 80-95% when 3 M HNO3 was used as the feed and followed the order: LIII > LII > LI > LIV while the UO22+ ion extraction was less than 4-5% and no particular trend could be established. The extraction of UO22+ could be partly due to the anionic nitrate complex of uranyl ion which was extracted in the absence of the ligands, while the ligand assisted extraction contributing for the remaining. Out of the other metal ions studied, Cs+ showed some extraction which was not ligand assisted while almost no extraction of metal ions such as Sr2+, Am3+ and Eu3+ was noticed. Unusually high selectivity was seen for Pu4+ ion extraction out of all the metal ions studied making the solvent systems very important for a plutonium specific separation method development. The extraction was found to be increasing with the aqueous phase nitric acid concentration conforming to a ‘solvation mechanism’ of extraction where the extracted species conforming to Pu(NO3)4·LIL for all the four diamide extractants.
