mixture. The ratio of the rate constants for the steps 2 to 1 of the reaction I is unfavorable for monoglycol formation. The distribution factor b ) k 1 /k 0 for a noncatalyzed reaction of ethylene oxide with water according to different data ...
Photocatalytic propertiesIn this research, CuFe2O4/Cu2O/Cu nanocomposites were synthesized by the solvothermal method. The consequences of ethylene glycol (ET) as a solvent on phase formation, morphology, and magnetic properties were studied. The powders showed high photocatalytic activity using ...

excited. The excitation energy is then transferred to the nearest C-H bond, resulting in the cleavage of this bond and the release of hydrogen, leading to polymer radical formation. The polymer radical can react with molecular oxygen, to produce polymer alkoxy (PO°) and hydroxyl (OH°) ...
Here, a different strategy for the preparation of ethylene glycol (EG) via initial oxidative coupling and subsequent reduction is presented. Separating coupling and reduction steps allows for a completely selective formation of EG (99%) from CO. This two-step catalytic procedure makes use of a ...
·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 ...
