Burns, Jonathan D. published the artcileAstatine partitioning between nitric acid and conventional solvents: indication of covalency in ketone complexation of AtO+, SDS of cas: 111-87-5, the main research area is astatine partitioning nitrate conventional solvent covalency ketone complexation.

Astatine-211 has been produced at Texas A&M University on the K150 cyclotron, with a yield of 890 ± 80 MBq through the 209Bi(α,2n)211At reaction via an 8 h bombardment with a beam current of 4-8 μA and an α-particle beam energy of 28.8 MeV. The target was then dissolved in HNO3 and the extraction of 211At was investigated into a variety of organic solvents in 1-3 M HNO3. Extraction of 211At with distribution ratios as high as 11.3 ± 0.6, 12.3 ± 0.8, 42.2 ± 2.2, 69 ± 4, and 95 ± 6 were observed for diisopropyl ether, 1-decanol, 1-octanol, 3-octanone, and Me iso-Bu ketone, resp., while the distribution ratios for 207Bi were â‰?.05 in all cases. The extraction of 211At into both Me iso-Bu ketone and 3-octanone showed a strong, linear dependence on the HNO3 initial aqueous concentration and better extraction than other solvents. DFT calculations show stronger binding between the carbonyl oxygen of the ketone and the At metal center.

Joshi, Nishant published the artcileReactive Extraction of Gallic Acid Using Tributyl Phosphate in Different Classes of Diluents, Related Products of alcohols-buliding-blocks, the main research area is reactive extraction gallic acid tributyl phosphate diluent octanol toluene; ethyl acetate hexane diluent reactive extraction gallic acid TBP.

Gallic acid is an important carboxylic acid used in pharmaceutical industries owing to its medicinal properties. The separation of gallic acid from fermentation broth and dilute aqueous streams is a challenging task. Therefore, in the present study the reactive extraction of gallic acid from an aqueous solution by using tri-Bu phosphate in octanol, Et acetate, n-hexane, and toluene as diluents, resp., has been carried out at constant temperature (303 ± 1 K). The results were compared with those of the extraction using pure diluents in order to compute the intensification of extraction obtained. Experiments were performed to investigate the effect of initial acid concentration, extractant concentration, and diluent type. TBP + hexane was found to be most suitable solvent system resulting in the highest distribution coefficient (KD = 24) when TBP was employed at a concentration of 1.516 mol·kg-1. The equilibrium complexation constant (KE) was observed to be in the ranges of 3.18-8.8 for n-hexane, 0.91-4.54 for toluene, 2.295-4.546 for Et acetate, and 3.57-6.17 for octanol.

Wei, Zheng published the artcileExtraction and separation performance of rhenium(VII) and uranium(VI) from nitric acid medium using N,N’-dimethyl-N,N’-dioctyldiglycolamide, Name: n-Octanol, the main research area is rhenium uranium ion extraction separation dimethyldioctyldiglycolamide complexation aqueous nitrate.

The extraction and separation of Re(VII) and U(VI) from the nitric acid medium were studied in which an asym. diglycolamide, N,N’-dimethyl-N,N’-dioctyldiglycolamide (DMDODGA) was used as the extractant, and 40/60(volume/volume)% n-octanol/kerosine was used as the diluent. The effects of the concentration of the aqueous HNO3, the initial metal ion and the extractant on the distribution ratios (DRe and DU) and the separation factor (βU/Re) are discussed. Formation of the 1:1 and 1:2 Re/DODMDGA and 1:1 U/DMDODGA complexes were also analyzed using the slope anal. method. Besides, βU/Re increases as the aqueous HNO3 concentration increases.

Yu, Shijie published the artcileBiphasic biocatalysis using a CO2-switchable Pickering emulsion, Safety of n-Octanol, the main research area is biphasic biocatalysis carbon dioxide nitrogen switchable Pickering emulsion; enzymic hydrolysis esterification switchable Pickering emulsion.

Biphasic biocatalyzes such as the hydrolysis of olive oil and the esterification of octanol with oleic acid were performed in a CO2/N2-switchable Pickering oil-in-water emulsion stabilized by silica nanoparticles hydrophobized in situ by a CO2/N2-switchable surfactant (N,N-dimethyldodecylamine). Compared with biphasic systems, the enzyme in the Pickering emulsions displays a higher reaction efficiency, and demulsification and recycling of the enzyme can be simply realized by bubbling with N2/CO2. Moreover, the recycled enzyme still possesses significant catalytic activity.

Jue, Erik published the artcileTwo-phase wash to solve the ubiquitous contaminant-carryover problem in commercial nucleic-acid extraction kits, Name: n-Octanol, the main research area is nucleic acid extraction two phase wash real time polymerase; chain reaction loop mediated isothermal amplification reverse transcription.

The success of fundamental and applied nucleic acid (NA) research depends on NA purity, but obtaining pure NAs from raw, unprocessed samples is challenging. Purification using solid-phase NA extractions utilizes sequential additions of lysis and wash buffers followed by elution. The resulting eluent contains NAs and carryover of extraction buffers. Typically, these inhibitory buffers are heavily diluted by the reaction mix (e.g., 10× dilution is 1μL eluent in 9μL reaction mix), but in applications requiring high sensitivity (e.g., single-cell sequencing, pathogen diagnostics) it is desirable to use low dilutions (e.g., 2×) to maximize NA concentration Here, we demonstrate pervasive carryover of inhibitory buffers into eluent when several com. sample-preparation kits are used following manufacturer protocols. At low eluent dilution (2-2.5×) we observed significant reaction inhibition of polymerase chain reaction (PCR), loop-mediated isothermal amplification (LAMP), and reverse transcription (RT). We developed a two-phase wash (TPW) method by adding a wash buffer with low water solubility prior to the elution step. The TPW reduces carryover of extraction buffers, phase-separates from the eluent, and does not reduce NA yield (measured by digital PCR). We validated the TPW for silica columns and magnetic beads by demonstrating significant improvements in performance and reproducibility of qPCR, LAMP, and RT reactions.

Rahimi, Atyeh published the artcileAnalysis of basic drugs in biological samples using dynamic single-interface hollow fiber liquid-phase microextraction combined with fast electromembrane extraction, Recommanded Product: n-Octanol, the main research area is hollow fiber liquid phase electromembrane microextraction.

In this study, a combination of single-interface hollow fiber liquid-phase microextraction and electromembrane extraction was applied for the extraction of some basic drugs from biol. samples. The extraction process was followed by the HPLC-UV instrument. In this dynamic system, 1-octanol was impregnated into the pores of hollow fiber wall as an acceptor phase, the sample solution (pH = 12.0) was pumped into the lumen of hollow fiber by a syringe pump, the extraction efficiency was improved by filling and emptying (25 times) of sample solution (step-1). The extracted analytes in the organic acceptor phase were back-extracted by a fast electromembrane extraction procedure (step-2). Under optimized conditions (organic acceptor phase: 1-octanol, sample solution volume: 1500μL, flow rate: 2.0 mL min-1, the number of filling and emptying cycles: 25, voltage: 100 V, back-extraction time: 2 min, and aqueous acceptor phase: 100 mM HCl), the proposed method provided good linearity with determination coefficients ranging from 0.992 to 0.996 over a concentration range of 2.5-1000 ng mL-1. The limits of detection were found to be within the range of 0.12-0.36 ng mL-1, while the corresponding repeatability ranged from 3.7 to 9.3% (n = 3). Finally, the optimized method was applied for the quantification of propranolol, diltiazem and, lidocaine in urine and, plasma samples with relative recoveries ranged between 94.1 and 105.4%, indicating the reliability of the method.

Sohani, Ali published the artcileDetermination of Hildebrand solubility parameter of pure 1-alkanols up to high pressures, COA of Formula: C8H18O, the main research area is alkanol Hildebrand solubility parameter determination monte carlo simulation.

An extended approach to determine Hildebrand solubility parameter (HISP) of pure 1-alkanols by precise calculation of the isothermal compressibility coefficient and heat capacities is proposed. The approach is introduced during its implementation for four pure polar 1-alkanols, namely 1-heptanol, 1-octanol, 1-nonanol, and 1-decanol. Having described the approach, the prediction ability of that is compared with the previous methods for calculation of the properties. Comparisons show that for all the three mentioned properties, the proposed approach provides significantly better predictions. The mean absolute error for prediction of the isothermal compressibility coefficient, isobaric heat capacity, and HISP by the proposed approach are 1.77, 1.32, and 0.17% (for 1-heptanol), 1.54, 1.11, and 0.18% (for 1-octanol), 2.90, 0.97, and 0.28% (for 1-nonanol), and 1.39, 1.61, and 0.39% (for 1-decanol), resp. In addition to checking the accuracy of the proposed approach, to investigate the impacts of temperature and pressure as two key parameters on HISP of 1-alkanols, sensitivity analyses are conducted. The results of sensitivity analyses show that same as the non-polar substances, in the case of polar compounds, increase in pressure leads to an increase in HISP. Furthermore, when temperature does not change, HISP approaches a constant value at high pressures. Moreover, the relationship between temperature and HISP is linear.

Zhang, Huan published the artcileExperimental investigation of heat and mass transfer in a LiBr-H2O solution falling film absorber on horizontal tubes: Comprehensive effects of tube types and surfactants, Recommanded Product: n-Octanol, the main research area is surfactant lithium bromide water solution falling film absorber tube.

This paper studied the effects of various surface geometries and surfactants on the LiBr-H2O solution falling film absorption, and the heat and mass transfer during the absorption process. Three different tubes (plain tube, floral tube and floral finned tube) were tested for the LiBr-H2O solution with two different surfactants (2-Ethyl-1-hexanol and 1-Octanol). The results indicate that the heat and mass transfer coefficients of each tube gradually decrease with solution falling down the tube bundle. It is also showed that the effect of surfactant on heat and mass transfer is obviously greater than that of tube surface geometry. Furthermore, with 2-Ethyl-1-hexanol as the surfactant, the heat and mass transfer can be improved by 400% and 350%, resp. The results of comparative study show that the heat and mass transfer performance of floral tubes with 2-Ethyl-1-hexanol is more stable and reliable than others.

Zsabka, Peter published the artcileSelective extraction of trivalent actinides using CyMe4BTPhen in the ionic liquid Aliquat-336 nitrate, Name: n-Octanol, the main research area is trivalent actinide ionic liquid aliquat336 nitrate phase transfer catalyst.

The extraction of Am(III), Cm(III) and Eu(III) by 2,9-bis(5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-1,2,4-benzotriazin-3-yl)-1,10-phenanthroline (CyMe4BTPhen) from nitric acid solution was studied using the ionic liquid Aliquat-336 nitrate ([A336][NO3]) as diluent. Results show a high selectivity of the solvent for Am(III) and Cm(III) over Eu(III), but rather slow extraction kinetics. The kinetics of CyMe4BTPhen were largely improved by the addition of 0.005 mol L-1N,N,N’,N’-tetra-n-octyl-diglycolamide (TODGA) as a phase transfer reagent and by the use of 1-octanol as co-diluent. The addition of the phase transfer catalyst and co-diluent did not compromise the selectivity towards the actinide/lanthanide separation and thus this four-component system can be successfully applied to sep. Am(III) and Cm(III) from the lanthanides.
