The chemical shift difference, Δσ, between the methylene and hydroxyl protons in the high resolution 1 H nuclear magnetic resonance spectrum of ethylene glycol is shown to be pressure dependent. The equilibrium Δσ values for ethylene glycol are reported as a function of temperature and pressure between ambient conditions, 323 K and 2 kbar, respecti...
The ability to manipulate droplets on a substrate using electric signals1-known as digital microfluidics-is used in optical2,3, biomedical4,5, thermal6 and electronic7 applications and has led to commercially available liquid lenses8 and diagnostics kits9,10. Such electrical actuation is mainly achieved by electrowetting, with droplets attracted to...

Context: This review discusses the range of clinical presentations seen with poisonings by the major toxic alcohols--methanol, ethylene glycol, and isopropyl alcohol. It outlines a straightforward diagnostic strategy and discusses in detail the current treatment recommendations. Evidence acquisition: The authors conducted a literature search of pri...
Highly branched Pt-Ni nanoalloys with varied chemical compositions were prepared by one-pot solvothermal synthesis. The morphology, structure, composition and catalytic properties of Pt-Ni nanoalloys were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), electrochemical cyclic voltammetry and chronoamperometry. The d...

The hydrogenation of ethylene carbonate to co-produce commodity methanol and ethylene glycol has attracted growing interests due to the potential chemical utilization of CO2 in large scale. In this work, we report a novel and facile protocol for the preparation of mesoporous [email protected] catalysts and successfully applied the as-synthesized catalysts in...
The efficient synthesis of methanol and ethylene glycol via the chemoselective hydrogenation of ethylene carbonate (EC) is important for the sustainable utilization of CO2 to produce commodity chemicals and fuels. In this work, a series of P-cyclodextrin-modified Cu/SiO2 catalysts were prepared by ammonia evaporation method for the selective hydrog...

An eight-step mechanism of esterification reaction between adipic acid (AA) and ethylene glycol (EG) catalyzed by tetrabutyl titanate [Ti(OBu)4] was studied in detail. The kinetic data for the esterification reaction between AA and EG catalyzed by tetrabutyl titanate [Ti(OBu)4] were measured in the temperature range of 403 K-433 K. A second-order k...

In this study, blend fibers composed of poly(vinyl alcohol) and poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) were prepared via wet-spinning technology. Ethylene glycol (EG) vapor annealing was employed to improve the electrical conductivity and tensile properties of blend fibers. The effects of EG vapor annealing on structur...
A series of Cu/SiO2-AE catalysts with different copper loadings were prepared by ammonia evaporation method with silica sol as the silica source. The systematic catalyst characterization revealed that different proportions of Cu degrees and Cu+ species co-existed in the Cu/SiO2-AE catalysts, which derived from the reduction of CuO and copper phyllo...
