This chapter discusses the reproductive and developmental toxicology of Ethylene Glycol (EG), which is a major industrial chemical, a compound poured into automobile radiators and sprayed onto airplane wings to

Polyethylene glycols (PEGs), polypropylene glycols (PPGs), and polytetramethylene glycol come under the class of polyethers and are used in pharmaceuticals, cosmetics, lubricants, inks, and surfactants. Flavobacterium sp. and Pseudomonas sp. together associate and mineralize PEG completely under aerobic ...
The ample supply outweighed China’s robust import demand. Buying interest in China was strong for April and May arrival cargoes, on the back of healthy downstream margins for certain downstream markets such as SM, EO and monoethylene glycol (MEG). Ethylene buyers in China were ...
Over the past decades, there have been numerous reports on the dispersion stabilization of gold nanoparticles (AuNPs), the most representative metal nanoparticles, using poly(ethylene glycol) (PEG) as a stabilizer, namely PEGylation11. PEG is a neutral water-soluble polymer with a flexible backbon...
The process comprises the steps of: stripping substantially a conventional polyethylene glycol alkyl ethers of ethylene glycol alkyl ether (R1O(CH2CH2O)H unit) and diethylene glycol alkyl ether (R1O(CH2CH2O)2H unit); reacting the stripped product with a compound having the formula (III) in the...
·5H2O), ascorbic acid (AA), sodium hydroxide (NaOH), potassium hydroxide (KOH), sodium chloride (NaCl), ethanol (>99.7%), isopropanol (>99.7%), diethanolamine (DEA > 99%), ethylene glycol (EG > 99%) were purchased from Macklin. Polyvinylpyrrolidone (PVP, K29-K32) and ...
Several studies propose the use of poly(ethylene glycol) (PEG) and non-ionic surfactants (such as Tween 80, Tween 20, and Triton X-100) as a way to increase cellulosic ethanol titers. The benefits attributed to the PEG and non-ionic surfactants go beyond the increase of the concentration ...
Ethylene glycol (EG, ethane-1,2-diol) is a major industrial chemical perhaps best known as the constituent in antifreeze for automobile radiators and the de-icer sprayed onto airplane wings to help keep them from freezing in the winter. Its largest use is in the production of polyester fibers...
Succinic acid (≥ 99.5%), ethylene glycol (anhydrous, 99.8%), titanium(IV) isopropoxide (Ti(iΟPr)4) (TIS) used for the synthesis of poly(ethylene succinate) (PESu) were purchased from Sigma-Aldrich (Saint Louis, MO, USA). All other reagents and solvents were of analytical grade. Jon...
