The NMR spectrum of ethylene oxide has been analyzed for carbon-13 satellites in the liquid crystal, Merck ZLI 1167. Structures derived from vibrationally corrected direct couplings indicate good agreement with gas-phase results. Application of vibrational corrections to previous couplings gives structural...
A triclinic unit cell (a = 1.17 nm, b = 1.20 nm, c = 1.06 nm, α = 78°, β = 64°, γ = 115°), containing eight ethylene oxide (EO) monomers and four hydroquinone molecules, has been determined from the analysis of the X-ray diffraction fiber patterns of stretched and sp...
poly(ethylene oxide); p-nitrophenol; molecular complexes; crystal structure Abstract A crystalline complex of poly(ethylene oxide) (PEO) and p-nitrophenol (PNP) was studied by differential scanning calorimetry, X-ray diffraction, and FTIR spectroscopy, The phase diagram of this system is characterize...
Glycol, any of a class of organic compounds belonging to the alcohol family; in the molecule of a glycol, two hydroxyl groups are attached to different carbon atoms. The term is often applied to the simplest member of the class, ethylene glycol. Learn mo
Ethylene is the starting material for the preparation of a number of two-carbon compounds including ethanol (industrial alcohol), ethylene oxide (converted to ethylene glycol for antifreeze and polyester fibres and films), acetaldehyde (converted to acetic acid), and vinyl chloride (converted to pol...
Ethylene Glycol (C2H6O2) - Ethylene glycol is the first member of the series of alkane diols and is also known as glycol. Ethylene glycol is a colorless liquid with the chemical formula C2H6O2. The molar mass of ethylene glycol is 62.07 g/mol.

WAXD, PLM, IR and TBA have been used to investigate the morphology, crystallinity, Tg and intermolecular interaction of PEO/PBHE blends as a function of composition and temperature. Up to a content of about 50 wt% of PEO the blend films are completely fi
A composite of poly(ethylene oxide) (PEO) and lignin (Lg) was prepared and characterized for its utility as an ultraviolet (UV) absorbing material. Due to the extensive UV absorption and excellent oxidation‐resistance of Lg, the formation of hydrogen bonds between the Lg particles and the ...
