Carbon dioxide induced degradation of diethanolamine during absorption and desorption processes

Alkanolamines are widely used in the purification of the sour gas sweetening process. During the sour gas absorption process, CO2 significantly degrades the amine solvent and creates enormous problems for plant operation. In this work, CO2 induced degradation of aqueous diethanolamine (DEA) solution was conducted in a 1.25 L jacketed glass reactor that functioned as an absorber and stripper at atmospheric conditions. Pure CO2 was bubbled through the reactor until the solution became saturated. In this study, the concentrations of DEA used were in the range of concentrations between 2 mol¡¤L? 1 and 4 mol¡¤L? 1. In the degradation experiment, six generic cycles were conducted for each run. Each cycle was configured with the absorption and desorption of carbon dioxide at 55 C and 100 C, respectively. Samples were collected after a predetermined experimental time and analyzed by ion chromatography (IC) to identify unknown ionic degradation products (DGPs). In the IC analysis, three different columns were used for anion, cation and ion exclusion systems, which are Metrosep A Supp 5 150/4.0, Metrosep C Supp 4 150/4.0 and Metrosep Organic Acids, respectively. The major identified DGPs of D01DEA2M, D02DEA3M, and D03DEA4M are nitrite, acetate and ammonium. Phosphate product was found in the degraded amine samples which might be due to the contamination of water or chromatographic system.

pH-sensitive assembly of light-harvesting dendrimer zinc porphyrin bearing peripheral groups of primary amine with poly(ethylene glycol)-b-poly(aspartic acid) in aqueous solution

The light-harvesting dendrimer zinc porphyrin [NH2CH2CH2NHCO]32DPZn, a potential photosensitizer in photodynamic therapy, was synthesized and successfully assembled with poly(ethylene glycol)-b-poly(aspartic acid) to form micelles in PBS buffer (10 mM) following the concept of polyion complex micelle. The coupling reaction between the [CO2H]32DPZn and N-trifluoroacetylethylene-l,2-diamine using the DCC/HOBt method afforded the protected dendrimer [CF3CONHCH2CH2NHCO]32DPZn, which was then mildly hydrolyzed to remove all the trifluoroacetyl protecting groups. Light-scattering measurements showed that the [NH2CH2CH2NHCO]32DPZn has the ability to assemble with poly(ethylene glycol)-b-poly(aspartic acid) to form a spherical micelle with a diameter of about 55 nm, having a narrow size polydispersity in PBS. The micelles were stable both in size and composition up to a 0.90 M (NaCl) salt concentration. The high salt stability is associated with a hydrogen-bonding network formed in the micellar core among the amide groups of the dendrimers and those of poly(aspartic acid) moieties, which could be destroyed by urea, a typical hydrogen-bonding cleaver. Furthermore, the pH range for the stable micelles in physiological saline (0.15 M NaCl) is from 6.2 to 7.4, suggesting the potential of the pH-triggered release of the entrapped dendrimers in the acidic pH environment (pH ? 5.0) of the intracellular endosomal compartment.

Calcitonin gene-related peptide (CGRP) receptor antagonists: Novel aspartates and succinates

Novel aspartate and succinate CGRP full antagonists were identified through core modification of a potent lead CGRP antagonist, BMS-694153. While aspartates were much less active and had a flat SAR, some of the succinates were very potent CGRP full antagonists and matched the potency of BMS-694153. The most potency resides in the S enantiomer as demonstrated through an asymmetric synthesis.

NOx reduction using amine reclaimer wastes (ARW) generated in post combustion CO2 capture

Amine reclaimer wastes (ARW) generated in CO2 capture processes demand suitable disposal means. Such wastes contain remaining amine, NH3 and other degradation compounds. This study investigated the potential of using ARW as a NOx reducing agent, under laboratory conditions in a flow reactor. A simulated flue gas containing about 500ppm of NO and 5% O2 was injected with liquid ARW under different stoichiometric ratios (TN/NO – total N to nitric oxide ratio) and temperatures. The ARW was obtained from a distillation monoethanolamine reclaimer in an industrial CO2 capture facility with a coal fired boiler. The results indicate that ARW has a significant NOx reduction potential when injected with TN/NO ratios in excess of 1. The optimum temperature is close to 950C, where 40% reduction in NOx is recorded with a TN/NO ratio of 1.6. Increasing TN/NO to 8.5 resulted in a 96% reduction. At low TN/NO ratios (<1.6), the NOx reduction potential of ARW is comparable to that of monoethanolamine, but lower than that of NH3. Nevertheless, the fact that ARW is a waste product, together with its demonstrated NOx reduction capability and its calorific value contribution, makes it attractive as an additive to combustion processes, including cement industry kilns.

Ionic liquids/ZnO nanoparticles as recyclable catalyst for polycarbonate depolymerization

A useful protocol for waste bis-phenol A-polycarbonates (BPA-PC) chemical recycling is proposed based on a bifunctional acid/basic catalyst composed by nanostructured zinc oxide and tetrabutylammonium chloride (ZnO-NPs/NBu4Cl) in quality of Lewis acid and base, respectively. Retro-polymerization reaction proved to be of general application for several nucleophiles, including water, alcohols, amines, polyols, aminols and polyamines, leading to the complete recovery of BPA monomer and enabling the PC polymer to function as a green carbonylating agent (green phosgene alternative) for preparing carbonates, urethanes and ureas. A complete depolymerization can be obtained in seven hours at 100 C and ZnO nanocatalyst can be recycled several times without sensible loss of activity. Remarkably, when polycarbonate is reacted with glycerol, it is possible to realize in a single process the conversion of two industrial wastes (BPA-PC and glycerol) into two valuable chemicals like BPA monomer and glycerol carbonate (the latter being a useful industrial solvent and fuel additive).
