Figure 2. Wallace Carothers attempted to form polymers from the reaction of ethylene glycol (a diol) and apidic acid (an aliphatic diacid). Figure 3. Glyptal polyester formation. Berzelius in 1847. They did not realize what they had discovered, however, and so moved on to other work. ...
The kinetics of the esterification reaction of hydroxymethyl(phenyl)phosphinic acid (HMPPA) with Ethylene Glycol (EG) was studied. The reaction was carried out using benzene as a water carrying agent, and the reactant concentration was determined by titration of NaOH solution. The reaction mechanism...
The selectivity of reactions of ethylene glycol with primary amines in the presence of RuCl 2 (PPh 3 ) 3 at 120掳C is highly dependent on the steric natur... JA Marsella - 《Journal of Organometallic Chemistry》 被引量: 24发表: 1991年 Process for producing 1, 3-dialkyl-2-imidazolidinone...

CoO nanosheets were synthesized based on the previously reported method30. In a typical procedure, 100 mg of Co(acac)3was added into a mixed solution, containing 20 ml of ethylene glycol and 4 ml of distilled water, followed by vigorous stirring for 30 min. Then the mixture was ...
(see the inset of Fig.4). The relatively stronger binding energy of glycerol compared to the reported binding energy of ethylene glycol on Mo2C (0001) surface (−1.07 eV calculated with PBE functional)15is due to binding of an additional oxygen atom to a Mo site and from the ...
Synthesis of precursors to ethylene glycol from formaldehyde and methyl formate catalyzed by heteropoly acids The production of ethylene glycol from methanol and its derivatives, such as formaldehyde, is potentially attractive, since the carbon needed for such a pr...
