One‐step catalytic synthesis of methyl acrylate from acetate and trioxane, with 90.7% yield 91.8% selectivity, was realized at 10–25°5. NMR analysis confirmed the ester enolization generation [i‐Pr 2 EtN‐H] + [TfO] − in presence i‐Pr EtN Bu BOTf, which affected by solvent base. The depolymerization trioxane into formaldehyde catalyzed BOTf. in‐situ mechanism efficiency determined analyzed. Mechanism‐based kinetic thermodynamic studies were conducted for better understanding this route. Also...
Direct synthesis of methyl acrylate from acetate and trioxane in liquid phase at mild condition.
Methylacrolein (MAL) is traditionally synthesized from propanal and formaldehyde via the Mannich reaction instead of aldol in homogeneous catalytic systems due to undesired self-condensation propanal. Herein, direct synthesis MAL trioxane was realized on an acid–base bifunctional Cs-P/γ-Al2O3 catalyst, which exhibited good stability could be prepared a large scale with 54.5% yield 100% selectivity. The influence P elements structure properties even selectivity MAL, compared Cs/γ-Al2O3,...
An ionic liquid catalyzed probase method for unsaturated ester synthesis under mild conditions was reported.
A series of Ni/γ-Al2O3 and Ni–Mo/γ-Al2O3 catalysts were prepared evaluated for the hydrogenation methyl acrylate to propionate in a fixed-bed reactor. Physicochemical characterizations these carried out with Brunauer–Emmett–Teller analysis, X-ray diffraction, UV–vis diffuse reflectance spectroscopy, Raman hydrogen temperature programed reduction, photoelectron transmission electron microscopy. It was noticed that Mo loaded onto catalyst could not only promote dispersion Ni particles but also...
Abstract An innovative technology for the production of methyl acrylate via vapor‐phase cross‐aldol condensation is described. Catalytic process intensification was realized through enhanced catalytic activity with oxygen by catalyst design and adjustment active sites. Crystal phases different V valences in vanadium phosphate catalysts were controllably synthesized presence oxygen. Donating electron withdrawing sites arose when moved from one crystalline phase to another, just α ‐H removal...

The are completed DSP (digital signal processor), so it can solve problems can't match subdivision system properly by logical judgement. Because utilizing high-speed optoelectronic convertor flash sample technique, process with wide frequency range. example demonstrated paper count divide signals from DC...
Abstract The treatment or upgrading of waste trifluoromethane (CHF 3 , R23), which has a significant greenhouse effect, is great importance in industry. Herein, series SO 4 2− /ZrO 2 ‐SiO catalysts with different Brønsted and Lewis acid site densities ratios were prepared for pyrolysis R23 to tetrafluoroethylene (C F TFE) hexafluoropropylene 6 HFP). effects impregnation concentration (NH ) on specific surface area, crystal phase, respectively demonstrated. sites observed have cooperative...
Abstract Polyoxymethylene dimethyl ethers (OMEs) emerging as green additives for soot emission suppression receive significant attention due to their similar physical properties diesel. Herein, the transformative pathways of dimethoxymethane (DMM) and trioxane reactions OMEs production catalyzed by [Omim]Cl/ZnCl 2 having different ZnCl content were demonstrated in combination with clarification active species, kinetic thermodynamic properties, chemical nature decomposition subsequential...
