Bacterial oxidation of 2-tridecanone to 1-Undecanol
J Bacteriol 1967 Feb;93(2):649-55.PMID:6020567DOI:10.1128/jb.93.2.649-655.1967.
A study of the microbial utilization of long-chain methyl ketones was under-taken. In general, enrichment culture experiments revealed that soil microorganisms capable of utilizing these compounds as growth substrates are ubiquitous. Gram-negative, rod-shaped bacteria were the prominent organisms exhibiting this capability. In particular, a strain of Pseudomonas isolated from soil degraded 2-tridecanone into several products that were recovered from cell-free culture fluid. These products were identified by gas-liquid chromatography as 2-tridecanol, 1-Undecanol, 1-decanol, and undecanoic acid. A large amount of the substrate was converted to 1-Undecanol. This compound was characterized further by classical methods of organic analysis. Unequivocal identification of 1-Undecanol has established that some unique mechanism that involves subterminal oxidation must exist to degrade 2-tridecanone. No such mechanism has been reported for the biological degradation of long-chain, aliphatic, methyl ketones. A pathway for utilization of 2-tridecanone was proposed that is consistent with, but not confirmed by, the data presented.
Lyotropic mixture made of potassium laurate/1-Undecanol/K2SO4/water presenting high birefringences and large biaxial nematic phase domain: a laser conoscopy study
Eur Phys J E Soft Matter 2012 Jun;35(6):50.PMID:22718499DOI:10.1140/epje/i2012-12050-9.
The lyotropic liquid crystalline quaternary mixture made of potassium laurate (KL), potassium sulphate, 1-Undecanol and water was investigated by experimental optical methods (optical microscopy and laser conoscopy). In a particular temperature and relative concentrations range, the three nematic phases (two uniaxial and one biaxial) were identified. The biaxial domain in the temperature/KL concentration surface is larger when compared to other lyotropic mixtures. Moreover, this new mixture gives nematic phases with higher birefringence than similar systems. The behavior of the symmetric tensor order parameter invariants σ (3) and σ (2) calculated from the measured optical birefringences supports that the uniaxial-to-biaxial transitions are of second order, described by a mean-field theory.
A highly hydrated α-cyclodextrin/1-Undecanol inclusion complex: crystal structure and hydrogen-bond network from high-resolution neutron diffraction at 20 K
Acta Crystallogr B Struct Sci Cryst Eng Mater 2013 Apr;69(Pt 2):214-27.PMID:23719708DOI:10.1107/S2052519213001772.
The monoclinic C2 crystal structure of an α-cyclodextrin/1-Undecanol host-guest inclusion complex was solved using single-crystal neutron diffraction. Large high-quality crystals were specially produced by optimizing temperature-controlled growth conditions. The hydrate crystallizes in a channel-type structure formed by head-to-head dimer units of α-cyclodextrin molecules stacked like coins in a roll. The alkyl chain of the guest lipid is entirely embedded inside the tubular cavity delimited by the α-cyclodextrin dimer and adopts an all-trans planar zigzag conformation, while the alcohol polar head group is outside close to the α-cyclodextrin primary hydroxyl groups. The cyclodextrin dimer forms columns, which adopt a quasi-square arrangement much less compact than the quasi-hexagonal close packing already observed in the less hydrated α-cyclodextrin channel-type structures usually found with similar linear guests. The lack of compactness of this crystal form is related to the high number of interstitial water molecules. The replacement of 1-Undecanol by 1-decanol does not modify the overall crystal structure of the hydrate as shown by additional X-ray diffraction investigations comparing the two host-guest assemblies. This is the first study that analyses the entire hydrogen-bonding network involved in the formation of a cyclodextrin dimer surrounded by its shell of water molecules.
On-chip electromembrane extraction of acidic drugs
Electrophoresis 2019 Sep;40(18-19):2514-2521.PMID:30916800DOI:10.1002/elps.201900024.
In the present work, a new supported liquid membrane (SLM) has been developed for on-chip electromembrane extraction of acidic drugs combined with HPLC or CE, providing significantly higher stability than those reported up to date. The target analytes are five widely used non-steroidal anti-inflammatory drugs (NSAIDs): ibuprofen (IBU), diclofenac (DIC), naproxen (NAX), ketoprofen (KTP) and salicylic acid (SAL). Two different microchip devices were used, both consisted basically of two poly(methyl methacrylate) (PMMA) plates with individual channels for acceptor and sample solutions, respectively, and a 25 µm thick porous polypropylene membrane impregnated with the organic solvent in between. The SLM consisting of a mixture of 1-Undecanol and 2-nitrophenyl octyl ether (NPOE) in a ratio 1:3 was found to be the most suitable liquid membrane for the extraction of these acidic drugs under dynamic conditions. It showed a long-term stability of at least 8 hours, a low system current around 20 µA, and recoveries over 94% for the target analytes. NPOE was included in the SLM to significantly decrease the extraction current compared to pure 1-Undecanol, while the extraction properties was almost unaffected. Moreover, it has been successfully applied to the determination of the target analytes in human urine samples, providing high extraction efficiency.
2-Nitroso-1-naphthol as a selective reagent for preconcentration of cobalt by vortex assisted combined with solidification of organic droplet and its determination by flame atomic absorption spectrometry
Environ Monit Assess 2013 Nov;185(11):9067-75.PMID:23649476DOI:10.1007/s10661-013-3236-x.
Highly rapid and selective vortex-assisted liquid-liquid microextraction based on solidification of organic drop has been used for determination of cobalt ion. 2-Nitroso-1-naphthol (2N1N) was used as a selective complexing agent to form stable cobalt-2N1N complex which can be extracted with 1-Undecanol at a short time by the assistance of vortex agitator system followed by its determination using flame atomic absorption spectrometry. In vortex assisted, vigorous vortex stream as well as the vibrant effect of vortex system cause very fine droplets of extraction solvent to be produced and extraction occurred at a short time. Some parameters influencing the extraction process such as pH of samples, concentration of 2-nitroso-1-naphthol, extraction solvent volume, extraction time, ionic strength and surfactant addition, as well as interferences were evaluated in detail and optimum conditions were selected. At the optimum conditions, the calibration curve was linear in the range of 15 to 400 μg L(-1) of cobalt ions. The relative standard deviation based on ten replicate analysis of sample solution containing 50 μg L(-1) of cobalt was 3.4%. The detection limit (calculated as the concentration equivalent to three times of the standard deviation of the blank divided by the slope of the calibration curve after preconcentration) was 5.4 μg L(-1). The accuracy of the proposed method was successfully evaluated by the analysis of certified reference materials. This selective and highly rapid method was used for determination of cobalt ions in different water samples.
