Results from MEA Degradation and Reclaiming Processes at the CO2 Technology Centre Mongstad

In 2015, the CO2 Technology Center Mongstad (TCM DA), operated a test campaign using aqueous monoethanolamine (MEA) solvent at 30 wt%. The main objective was to demonstrate and document the performance of the TCM DA Amine Plant located in Mongstad, Norway. As part of the test campaign, thermal reclaiming was performed in order to eliminate accumulated degradation products and improve the solvent performance. This paper presents results and discussions concerning formation and monitoring of amine degradation products along with experiences related to the thermal reclaiming process and its operational procedure. Evaluations of the efficiency of thermal reclaiming and the solvent improvement after reclaiming are also presented. Published by Elsevier Ltd.

Bacteria isolated from kidney recipients with urinary tract infections: Epidemiology and susceptibility of the strains

Purpose: The incidence, type, and frequency of antimicrobial resistance of bacteria isolated from kidney recipients with bacterial urinary tract infections (UTIs) was evaluated. Methods: From 2007 to 2015, 1307 consecutive kidney recipients were studied retrospectively for patient demographics, clinical characteristics and urine culture data. Results: A total of 86 (6.6%) patients experienced 102 culture-proved bacterial UTI episodes. Three (3.5%) septic shocks occurred in these 86 patients and 1(1.2%) patients developed UTI-related mortality. The most frequently isolated species were Gramnegative bacteria (68.6%) with E.coli (42.2%) being the most prevalent bacterium. The Gram-negative bacteria were highly resistant to 1st- and 2nd-generation cephalosporin, monocyclic beta lactam and relatively sensitive to meropenem, amikacin and cefoperazone/ sulbactam, with the resistance rates of 85.7%, 85.7%, 81.4%, 21.4%, 21.4% and 28.6%, respectively. More than half (71.4%, 50/70) of Gram-negative bacteria were caused by extended-spectrum beta-lactamase (ESBL) producing strains. All Gram-positive bacteria were susceptible to teicoplanin and linezolid whereas 12.5% of them were resistant to vancomycin. Conclusions: The Gram-negative bacteria were relatively susceptible to meropenem, amikacin and cefoperazone/sulbactam and most of Gram-positive bacteria were susceptible to glycopeptides and oxazolidone. The majority of Gram-negative bacteria were ESBL+ strains and vancomycin-resistant enterococci accounted for 13.6% of all enterococci.

Decarboxylative sp 3 C-N coupling via dual copper and photoredox catalysis

Over the past three decades, considerable progress has been made in the development of methods to construct sp 2 carbon-nitrogen (C-N) bonds using palladium, copper or nickel catalysis 1,2 . However, the incorporation of alkyl substrates to form sp 3 C-N bonds remains one of the major challenges in the field of cross-coupling chemistry. Here we demonstrate that the synergistic combination of copper catalysis and photoredox catalysis can provide a general platform from which to address this challenge. This cross-coupling system uses naturally abundant alkyl carboxylic acids and commercially available nitrogen nucleophiles as coupling partners. It is applicable to a wide variety of primary, secondary and tertiary alkyl carboxylic acids (through iodonium activation), as well as a vast array of nitrogen nucleophiles: nitrogen heterocycles, amides, sulfonamides and anilines can undergo C-N coupling to provide N-alkyl products in good to excellent efficiency, at room temperature and on short timescales (five minutes to one hour). We demonstrate that this C-N coupling protocol proceeds with high regioselectivity using substrates that contain several amine groups, and can also be applied to complex drug molecules, enabling the rapid construction of molecular complexity and the late-stage functionalization of bioactive pharmaceuticals.

N-Acylation of Oxazolidinones via Aerobic Oxidative NHC Catalysis

The first N-acylation of synthetically useful oxazolidinones with aldehydes using aerobic oxidative NHC catalysis is reported. The reaction offers a broad scope of functionalized oxazolidinones in good to excellent yields. Careful choice of electron transfer mediators proved pivotal to achieve efficient aerobic N-acylation, which has previously proven difficult using NHC catalysis. The methodology allows a mild entry to acylated oxazolidinones, avoiding the use of hazardous and reactive prefunctionalized substrates.

Norbornyl dipeptide analogues: Mimics of both a transition state and a torsionally distorted ground state

The 1-amino-2-hydroxybicyclo[2.2.1]heptane-7 acid derivatives 1-3 have been synthesized, the pivotal step being the use of an acyl nitrene-insertion reaction to introduce nitrogen functionality into the corresponding hydroxy ester. The analogues each mimic a distorted peptide ground state as well as the transition state for peptide bond hydrolysis. To enhance the immune response and to provide further sequence specificity, the analogues 1-3 have been coupled to at least one D-amino acid residue to yield the derivatives 21, 26, and 27, respectively. Antibodies elicited against these derivatives may catalyze the hydrolysis of the corresponding peptides both by straining the substrate ground state and by stabilizing the transition state.

Cycloaddition of styrene oxide and CO2 mediated by pyrolysis of urea

This paper reports the effectiveness of carrying out the cycloaddition reaction of styrene oxide (SO) and CO2 without the use of any catalysts. A naturally abundant and cheap material, urea, was utilized in promoting the reaction by controlling the reaction conditions. The influence of reaction temperature, carbon dioxide (CO2) pressure, amount of urea, and the reaction time on the selectivity of styrene carbonate (SC) was investigated.

KCC-1 Supported Ruthenium-Salen-Bridged Ionic Networks as a Reusable Catalyst for the Cycloaddition of Propargylic Amines and CO2

Abstract: This study investigates the potential application of an efficient, easily recoverable and reusable KCC-1 nanoparticle-supported Salen/Ru(II) catalyst in the synthesis of 2-oxazolidinones from CO2, and propargylic amines. The KCC-1/Salen/Ru(II) NPs were thoroughly characterized by using TEM, SEM, TGA, FT-IR, ICP-MS, and BET. This observation was exploited in the direct and selective chemical fixation of CO2, affording high degrees of CO2 capture and conversion. The recycled catalyst has been analyzed by ICP-MS showing only minor changes in the morphology after the reaction, thus confirming the robustness of the catalyst.
