Thermal degradation of novel piperazine-based amine blends for CO2 capture

36 novel piperazine (PZ)-based amine blends were investigated for their thermal stability for CO2 capture. These amines include 7 imidazoles, 8 cyclic and long-chain diamines, 12 tertiary amines, 4 hindered amines, 3 hindered and tertiary amino acids, and 2 ether amines that were selected based on known amine structure-property relationships and their potential for industrial application. 18 thermally stable PZ-based amine blends were identified based on their degradation rates in CO2 loaded solutions at 150 and 175 C. Degradation mechanisms were studied to understand the relationships between the structure and thermal stability of the blended amines of the blends.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Recommanded Product: Oxazolidin-2-one, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 497-25-6, in my other articles.

Toward polymers with oxazolidin-2-one building blocks through tetra-n-butyl-ammonium halides (Cl, Br, I) catalyzed coupling of epoxides with isocyanates

The selectivity of the reaction of 4,4-methylene diphenyl diisocyanate MDI with o-cresyl glycidyl ether OCGE yielding oxazolidin-2-one and isocyanurates, and applying tetra-n-butyl ammonium halide as catalysts is higher in the order chloride, bromide, iodide. The dominant reaction pathways were inferred from the reactivity of the system with various ratios of MDI to OCGE, and using IR spectroscopy to monitor the progress. The reaction proceeds in several steps with initial nucleophilic attack of the halide on the epoxide yielding an alkoxide intermediate. The alkoxide reacts with isocyanate to yield a carbamato intermediate that may either ring close to form oxazolidinone or catalytically form isocyanurates by addition of more isocyanate and backbiting. The formation of isocyanurate is the reaction with the lowest activation barrier. Isocyanurate acts also as an isocyanate precursor as it is ring opened by the alkoxide intermediates in a slower consecutive process. Oxazolidinone modified epoxy prepolymers could be prepared from bisphenol A diglycidyl ether and MDI.

Stereoselective Synthesis of Highly Substituted Tetrahydropyrans through an Evans Aldol-Prins Strategy

A direct and general method for the synthesis of naturally occurring 2,3,4,5,6-pentasubstituted tetrahydropyrans has been developed, employing beta,gamma-unsaturated N-acyl oxazolidin-2-ones as key starting materials. The combination of the Evans aldol addition and the Prins cyclization allowed the diastereoselective and efficient generation of the desired oxacycles in two fashions: a one-pot Evans aldol-Prins protocol, in which five new sigma bonds and five contiguous stereocenters were straightforwardly generated, and a two-step version, which additionally permitted the isolation of beta,gamma-unsaturated alcohol precursors bearing an N-acyl oxazolidin-2-one in the alpha position. From these alcohols were also obtained halogenated pentasubstituted tetrahydropyrans as well as 2,3,4,5-tetrasubstituted tetrahydrofurans, shedding light on the mechanism of the process. Computational studies were consistent with the experimental findings, and this innovative Evans aldol-Prins strategy was performed for the preparation of a battery of more than 30 densely substituted tetrahydropyrans, unprecedentedly fused to a 1,3-oxazinane-2,4-dione ring, both in a racemic fashion and in an enantiomeric fashion. These novel molecules were successfully submitted to several transformations to permit simple access to a variety of differently functionalized tetrahydropyrans. Most of these unique molecules were evaluated for their antimicrobial activity against Gram-positive and Gram-negative bacteria and the yeast Candida albicans, and some structure-activity relationships were established.

Recent developments in glycosyl urea synthesis

The area of sugar urea derivatives has received considerable attention in recent years because of the unique structural properties and activities that these compounds display. The urea-linkage at the anomeric center is a robust alternative to the naturally occurring O- and N-glycosidic linkages of oligosaccharides and glycoconjugates, and the natural products that have been identified to contain these structures show remarkable biological activity. While methods for installing the beta-urea-linkage at the anomeric center have been around for decades, the first synthesis of alpha-urea glycosides has been much more recent. In either case, the selective synthesis of glycosyl ureas can be quite challenging, and a mixture of alpha- and -isomers will often result. This paper will provide a comprehensive review of the synthetic approaches to alpha- and -urea glycosides and examine the structure and activity of the natural products and their analogues that have been identified to contain them.

Synthesis of new beta- and gamma-aminopyrrolidinephosphonates via 1,3-dipolar cycloaddition of substituted vinylphosphonates

Synthesis of alpha- and beta-(aminomethyl)vinylphosphonates was achieved from vinyl bromide via a cross-coupling reaction with triethyl phosphite and by cross-metathesis of allyl bromide and vinylphosphonate, respectively. The 1,3-dipolar cycloaddition of these vinylphosphonates with a dipole in the presence of trifluoroacetic acid afforded selectively the beta-aminopyrrolidinephosphonates. Syntheses of cis- and trans-gamma-aminopyrrolidinephosphonates are also described.

Vinyl ester resin modified with acrylated epoxidised soybean (AESO) and linseed (AELO) oils: Effect of additional urethane crosslinking

Bisphenol A-based vinyl ester resin (VE) was modified with acrylated epoxidised soybean and linseed oils (AESO and AELO, respectively) in 10 wt.%. The double bond/epoxy ratio in these functionalised vegetable oils was practically the same, i.e. 30/70%, allowing us to deduce effects caused by the different unsaturations in the parent oils. The crosslink density of the resins was enhanced by adding polyisocyanate. The glass transition temperature (Tg) of the hybrids was determined by differential scanning calorimetry (DSC) and dynamic mechanical thermal analysis (DMTA). Resistance to thermal degradation was assessed by thermogravimetric analysis (TGA). The fracture toughness and energy (Kc and Gc, respectively) were determined on compact tension specimens at room temperature. Incorporation of AESO and AELO reduced the Tg of VE along with slight reductions in the Kc and Gc data. The Tg reduction was less for AELO than AESO which was attributed to the higher functionality of AELO compared to AESO. Urethane crosslinking of VE (VEUH) prominently enhanced the Tg. Modification of VEUH with AES(L)O enhanced the Tg due to additional crosslinks. Urethane hybridisation was associated with a strong decrease in both Kc and Gc compared to those of the parent VE. Kc and Gc of VEUH did not change practically as a function of blending with AES(L)O. Incorporation of AES(L)O reduced the resistance to thermal degradation of both VE and VEUH.
