2,5-Furandicarboxylic acid (FDCA) serves as a monomer in various polyesters and is often obtained through the oxidation of 5-hydroxymethylfurfural. The solubility data FDCA are great value for reaction process analysis separation technology. experimental eight pure solvents (water, methanol, acetonitrile, acetic acid, ethyl acetate, methyl isobutyl ketone (MIBK), 1-butanol, isobutanol) two binary solvent systems (water + acetonitrile water acid) temperature range 313.15–363.15 K was...
Efficient transformation of glucose to 5-hydroxymethylfurfural (5-HMF) through the synergistic interaction Lewis acid, Brønsted and basic sites in MIL-53(Al).
Whether time-modulated pulsed-electron imaging in ultrafast electron microscopy (UEM) can mitigate the radiation damage that occurs to samples, is still controversial. The effectiveness of such mitigation effect and relevant potential application cryo-EM remain be explored. Herein, we built an (cryo-UEM) device based on laser system. Using equipment saturated aliphatic hydrocarbon compounds (C44H90), fading curves diffraction intensity corresponding critical doses (Ne) samples were carefully...
Strong electron-photon interactions occurring in a dielectric laser accelerator provide the potential for development of compact electron accelerator. Theoretically, metallic materials exhibiting notable surface plasmon-field enhancements can possibly generate high acceleration capability. Here, we present design material-based on-chip laser-driven accelerators that show remarkable capability, as demonstrated ultrafast microscopy investigations. Under phase-matching conditions, efficient and...
5‐hydroxymethylfurfural (5‐HMF) has been considered as an important biomass‐based platform chemical for its wide applications. Currently, the production of 5‐HMF from catalytic dehydration glucose is preferred, in which Brønsted and Lewis acids catalysts play role. Here, it was found that MIL‐53(Al) modified with tin active, selective, reusable catalyst transformation to dimethyl sulfoxide (DMSO) solvent. Around 42.3% yield 93% conversion achieved, when prepared metal‐organic frameworks...
Abstract A detailed radical chain elementary reaction mechanism for the liquid‐phase catalytic oxidation of meta‐xylene to meta‐phthalic acid catalyzed by cobalt acetate and manganese promoted hydrogen bromide was proposed. Using several reasonable assumptions a simple fractional‐like kinetic model derived from assumed mechanism. Several batch experiments were carried out study kinetics. The included three values initial concentration four temperature. developed parameters determined in...
Liquid–liquid equilibrium (LLE) data was very important for the process design and optimization of 5-hydroxymethylfurfural (5-HMF) production. To provide this fundamental data, experimental liquid–liquid ternary systems, {water + 5-HMF 1-butanol}, isobutanol}, methyl isobutyl ketone}, were measured at 313.15, 323.15, 333.15 K. Partition coefficients used to assess extraction capacity organic solvents in biphasic systems. 1-Butanol isobutanol desirable extractants with good performance...

Understanding the photoinduced ultrafast structural transitions and electronic dynamics in single-walled carbon nanotubes (SWCNTs) is important for development of SWCNT-based optoelectronic devices. In this study, we conducted femtosecond-resolved electron diffraction energy-loss spectroscopy (EELS) measurements on SWCNTs using transmission microscopy.
