Parallel microwave-assisted synthesis of ionic liquids and screening for denitrogenation of straight-run diesel feed by liquid-liquid extraction

Fifty-six ionic liquids were efficiently synthesized in parallel format under one-pot, solvent-free microwaveassisted synthesis. These compounds were evaluated as extracting agents of nitrogen-containing compounds from a real Diesel feed before being submitted to the hydrodesulfurization process to obtain ultralow sulfur Diesel. Our results showed that halogenated ionic liquids are an excellent alternative due to these ionic liquids are relatively inexpensive, presenting a high selectivity for the extraction of nitrogen-containing compounds and can be regenerated and recycled.

Configurational assignment of vic-amino alcohols from their circular dichroism spectra with dirhodium tetracetate as an auxiliary chromophore

The circular dichroism spectra of a variety of vic-amino alcohols in the presence of dirhodium tetraacetate as an auxiliary chromophore were measured in ethanol as the solvent. The method was tested with several model compounds, representing both acyclic and cyclic amino alcohols, including biologically important adrenergic drugs as well as amino sugars. The study demonstrated that the sign of the Cotton effects is determined by the preferred helicity of the O-C-C-N unit in the chiral complex formed in situ. The combined analysis of the CD, UV-vis, 1H and 13C NMR indicated predisposition to form chiral complexes by initial coordination of the amino alcohol at the axial coordination site followed by migration to the equatorial position. Finally, after migration of the ligand to an equatorial position(s) a bridging or a chelating complex is formed. Hence, vic-amino alcohols in ethanol act as bidentate ligands in the end.

Enantioselective Synthesis of N-Benzylic Heterocycles: A Nickel and Photoredox Dual Catalysis Approach

Reported herein is a dual nickel- and photoredox-catalyzed modular approach for the preparation of enantioenriched N-benzylic heterocycles. alpha-Heterocyclic carboxylic acids, easily obtainable from common commercial material, are reported as suitable substrates for a decarboxylative strategy in conjunction with a chiral pyridine-oxazoline (PyOx) ligand, providing quick access to enantioenriched drug-like products. The presence of a directing group on the heterocyclic moiety is shown to be beneficial, affording improved stereoselectivity in a number of cases.

Chemical profiling of liposoluble liquid smokes obtained from Eucalyptus wood tar: confirmation of absence of polycyclic aromatic hydrocarbons

Liposoluble liquid smoke (LS) preparations are versatile food additives used worldwide. The objective of the present work was to characterise the chemical composition of four types of industrial liposoluble LS currently used as the basis for the production of commercial smoke flavourings. The LS was obtained by vacuum fractional distillation from a raw pyrolysis oil (raw LS) obtained primarily from eucalyptus wood tar. The raw LS and the four LS flavourings obtained therefrom were analysed by gas chromatography/mass spectrometry (GC/MS) to characterise the main groups of components. Additional analyses were carried out to evaluate the occurrence of PAHs (polycyclic aromatic hydrocarbons) in the samples, as the producer claimed that these samples are free of PAHs. The main chemical components characterised in the LS were organic acids, aldehydes, esters, furans, pyrans and phenols, with phenolic compounds being the major chemical group. For the four LS tested samples, no PAHs could be detected with the method employed, which could indicate that the industrial processing was able to effectively remove this harmful class of compounds, or at least decrease its concentrations to levels below the limits of detection of the method of analysis.

Denitrogenation of middle distillates using adsorbent materials towards ULSD production: A review

A review of the state of art in the denitrogenation process of middle distillates using adsorbent materials is discussed. More stringent environmental laws enforce refiners to produce cleaner fuels from heavy feeds. Sulfur compounds reduce fuel quality and release pollutants to the atmosphere by which its elimination is mandatory. Typical hydrodesulfurization (HDS) catalytic processes in refineries are limited to meet the required specifications for Ultra Low Sulfur Diesel (ULSD) and new processes and materials need to be developed. Removal of nitrogen compounds (N-compounds) from real feedstocks improves sulfur elimination because irreversible adsorption of N-compounds on acidic sites in HDS catalysts may be avoided. Research and development during the last decade is reviewed in this work, including results obtained with different types of N-compounds, adsorptive systems and adsorbents commercially available.
