Methyl cis-6,cis-9,cis-12-octadecatrienoate-15,15,16,16-d4 and the corresponding cis,cis,trans isomer were obtained by coupling hexyl-d4-triphenylphosphonium bromide and methyl 12-oxo-cis-6,cis-9-dodecadienoate by the Wittig reaction. The deuterated phosphonium salt was prepared from 3-hexynol b...
The experimental study of the oxidation of a blend containing n-decane and a large unsaturated ester, methyl oleate, was performed in a jet-stirred reactor over a wide range of temperature covering both low and high temperature regions (550–1100 K), at a residence time of 1.5 s, at quasi atmosp...
The existing information supports the use of this material as described in this safety assessment. Methyl 2-nonenoate was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental...
sThe complexes of di-μ-chlorobis(1,5-cyclooctadiene) of rhodium(I); [Rh(μ-Cl)(COD)]2 and iridium(I); [Ir(μ-Cl)(COD)]2 have shown prominent activities in a number of catalytic reactions. In the solid packing form these two complexes were shown to adopt D2h and C2v symmetries for iridium and rh...
Reaction of [Ru(COD)Cl2]x (COD = 1,5-cyclooctadiene) with pyridine-2,6-dicarboxylic acid (dipicH2) in the presence of Et3N afforded an anionic complex [Et3NH][(dipic)(COD)RuCl] (1) with a κ3-dipic coordination mode. Treatment of 1 with AgNO3 in MeOH/H2O afforded a neutral complex [(dipic)(COD)R...
Through the study of the critical solution temperature of ionic liquids [CH3(OCH2CH2)nN+Et3][CH3SO3−] (ILPEG, n = 12, 16, 22), ILPEG-stabilized Rh nanoparticle catalysts have been found to function as thermoregulated phase-separable catalysts and have been shown to be efficient and recyclable fo...
The structure of the stable Pd(0) precatalyst [(1,5-cyclooctadiene)(L·Pd)2] (L = AdBrettPhos) for the Pd-catalyzed fluorination of aryl triflates has been further studied by solid state NMR and X-ray cystrallography of the analogous N-phenylmaleimide complex. The reactivity of this complex with...
The adsorption and reaction of 1,5-cyclooctadiene with the Ge(1 0 0) surface has been investigated. The subsequent surface reactions are followed by photoelectron spectroscopy and temperature programmed desorption. The bonding configuration is determined with photoelectron spectroscopy and compa...
Palladium (Pd) was incorporated into TUD-1 mesoporous siliceous material by using one-pot synthesis procedure. The catalytic activity of the prepared samples was evaluated in the selective hydrogenation of 1,5-cyclooctadiene (COD) at 80 °C in a solvent-free condition. Pd-TUD-1 showed > 95% conv...
Here, different loading of palladium (Pd), ranged from 0.5 to 5 wt%, was incorporated into the three dimensional siliceous mesoporous material; TUD-1. The synthesis procedure was carried out without the use of solvents, surfactants, and/or copolymers. Only triethanolamine and water with the prec...
In this study, the interactions between volatile organic compounds and the ionic liquid (IL) 1-ethyl-3-methylimidazolium 2-(2-methoxyethoxy) ethylsulfate [EMIM]+[MDEGSO4]− were investigated using gas + liquid chromatography measurements. The activity coefficients at infinite dilution γ13∞ were...
An accurate and precise procedure was developed for the detection and quantification of (2-methoxyethoxy)acetic acid (MEAA), a metabolite and biomarker for human exposure to 2-(2-methoxyethoxy)ethanol. The compound 2-(2-methoxyethoxy)ethanol has a wide array of industrial applications including ...
The application of ammonia acetate buffered liquid chromatography (LC) eluents is known to concomitantly lead to ion suppression when electrospray ionization mass spectrometry (ESI–MS) detection is used. In negative ESI mode, post column infusion of 2-(2-methoxyethoxy)ethanol (2-MEE) was shown ...
The objective of this study was to understand the adsorption ability of a surfactant and a non-surfactant chemical additive used in hydraulic fracturing onto shale and GAC. Experiments were performed at varying temperatures and sodium chloride concentrations to establish these impacts on the ads...
The removal of 2-butoxyethanol from gaseous emissions was studied using two biotrickling filters (BTF1 and BTF2) packed with polyurethane foam. Two different inoculum sources were used: a pure culture of Pseudomonas sp. BOE200 (BTF1) and activated sludge from a municipal wastewater treatment pla...
