Synthetic Route of 497-25-6, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 497-25-6, Name is Oxazolidin-2-one, molecular formula is C3H5NO2. In a Article，once mentioned of 497-25-6

A study was conducted to evaluate the mechanical properties of low density fiberboard produced with combinations of two fibers soybean straw (Glycine max), and wheat straw (Triticum aestivum) and two resins methylene diphenyl diisocyanate (MDI) and epoxidized sucrose soyate (ESS) resin as binders. ESS is a high performance, soybean oil based epoxy that has shown promise as a highly biobased adhesive. Six formulations of panels were produced using various combinations of straw and resin binder. Mechanical testing of sample boards was conducted using ASTM standard D1037-12. Test results showed that type of resin did not influence soy straw or wheat straw board’s stiffness and strength properties but had a major impact on water resistance, screw withdrawal strength and internal bond strength. The study demonstrated the potential of ESS as a novel binder for fiberboard system if a suitable crosslinker and catalyst is utilized. It also showed that increasing ESS content over 50% in a MDI blend lowered the performance characteristics of boards. However, analytical testing of the resin systems showed limited reactivity between ESS soyate and MDI, indicating other compatible resin chemistries should be explored for achieving superior board properties. Overall, a resin blend with 25?50% ESS in MDI appears favorable for low density fiberboards. ESS can be a promising bio-based resin as it has the potential to meet California Air and Resources Board (CARB) standards while providing acceptable properties as an adhesive.

A highly efficient copper(i)-catalyzed asymmetric 1,3-dipolar cycloaddition of azomethine ylides with benzo[b]thiophene 1,1-dioxides as the dipolarophiles was developed, providing elegant access to novel chiral tricyclic pyrrolidine-fused benzo[b]thiophene 1,1-dioxide derivatives in good to excellent yields (up to 99%) with excellent diastereo- and enantioselectivities (up to >25:1 dr, up to 99% ee). Furthermore, the cycloadducts could be conveniently converted to synthetically important tricyclic pyrrolidine-fused benzo[b]thiophene and tetracyclic oxazolidin-2-one derivatives via simple transformations.

Application of 695-53-4, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 695-53-4, 5,5-Dimethyloxazolidine-2,4-dione, introducing its new discovery.

Pregnant rats treated with dimethadione (DMO), the N-demethylated metabolite of the anticonvulsant trimethadione, produce offspring having a 74% incidence of congenital heart defects (CHD); however, the incidence of CHD has high inter-litter variability (40-100%) that presents a challenge when studying the initiating events prior to the presentation of an abnormal phenotype. We hypothesized that the variability in CHD incidence was the result of differences in maternal systemic concentrations or embryonic tissue concentrations of DMO. To test this hypothesis, dams were administered 300. mg/kg DMO every 12. h from the evening of gestational day (GD) 8 until the morning of GD 11 (six total doses). Maternal serum levels of DMO were assessed on GD 11, 12, 13, 14, 15, 18 and 21. Embryonic tissue concentrations of DMO were assessed on GD 11, 12, 13 and 14. In a separate cohort of GD 12 embryos, DMO concentrations and parameters of growth and development were assessed to determine if tissue levels of DMO were correlated with these endpoints. Embryos were exposed directly to different concentrations of DMO with whole embryo culture (WEC) and their growth and development assessed. Key findings were that neither maternal systemic concentrations nor tissue concentrations of DMO identified embryos that were sensitive or resistant to DMO in vivo. Direct exposure of embryos to DMO via WEC also failed to show correlations between embryonic concentrations of DMO with developmental outcomes in vitro. We conclude that neither maternal serum nor embryonic tissue concentrations of DMO predict embryonic outcome.

Quantitative online NMR spectroscopy was used for studying the species distribution in solutions of carbon dioxide in aqueous monoethanolamine (MEA) and diethanolamine (DEA). The mass fraction of the amine in the unloaded solution was 0.2 and 0.3 g/g, respectively, the carbon dioxide loading was up to 1.1 mo lC O2 / mo lamine, temperatures were between 293 and 353 K. A special apparatus was designed that allows preparing the mixtures gravimetrically and applying pressures up to 25 bar to keep the carbon dioxide in solution. It was coupled to a 400 MHz NMR spectrometer by heated capillaries. By using both 1H and 13C NMR spectroscopy quantitative information on the concentrations of the following species were obtained: amine, carbamate, bicarbonate, and carbon dioxide. Due to the fast proton transfer between molecular and protonated amine, only the sum of their concentrations can be determined. Furthermore, a byproduct, 2-oxazolidone, was observed and quantified. The experimental data were used for developing a thermodynamic model of the studied electrolyte solutions based on the extended Pitzer GE-model. In the model development, also vapor-liquid equilibrium data from the literature were included. The model gives reliable results both for the species distribution and the vapor-liquid equilibrium of the studied mixtures.

A new method for the preparation of Xxx-Gly (E)-alkene dipeptide isosteres (EADIs), using LDA deprotonation followed by 1 N HCl quench, was explored. The method, named kinetic deconjugation, enabled the synthesis of Tyr-Gly, Gly-Gly, Ser-Gly, Pro-Gly, and Phe-Gly EADIs, as well as one Tyr-Gly trisubstituted alkene dipeptide isostere (TADI). Overall, this method, based on commercially available materials, leads to high yields, requires few synthetic steps and works on the gram scale in the synthesis of a wide variety of EADIs.
