The data obtained from NMR and IR spectroscopy investigations in diethyl ether show that this complex is the dominant species.
Although further research is necessary, the use of ethyl acetate proves to be very promising and presents a valid alternative to the use of diethyl ether and, in many cases, also to carbon dioxide and chilling.
The number of acidic and strong basic sites could be correlated with the extent of ethylene and diethyl ether by-product formation.
Diethyl ether seems to be the better of the two.
- The diethyl ether complexes are more reactive than those with dioxane or THF.
The latter is particularly effective in the case of ethyl acetate and ether.
Therefore, the proposed micro ethyl acetate method can be used for routine analysis.

Are there any expanded polystyrene films with ethyl acetate made by casting?4 answersFilms of expanded polystyrene with ethyl acetate have been fabricated by casting drops of solutions onto a glass substrate. The interaction between the solution and the casting substrate influences film formation, surface morphology, and hydrophilicity. The competition between solution drop spreading and solvent evaporation controls polymer crystallization and film properties, with ethyl lactate providing better wetting properties and slower evaporation rates compared to ethyl acetate, resulting in thinner films. Additionally, the mass transport of ethyl acetate in syndiotactic polystyrene has been studied, showing anomalous transport behavior with two stages of sorption curves and different diffusion patterns in press-cooled and water-quenched specimens. These findings contribute to understanding the fabrication and properties of expanded polystyrene films with ethyl acetate through casting processes.
Concentration of ethyl acetate affecting sulfur analysis in white wine ?5 answersThe concentration of ethyl acetate in white wine can impact the analysis of sulfur compounds. Research has shown that ethyl acetate, when present in high levels exceeding the human perception threshold, can lead to a spoiled aroma in wine. Additionally, studies have highlighted that the addition of compounds like caffeic acid and glutathione can help protect aromatic volatiles in white wine with reduced sulfur dioxide levels. Understanding the interactions between different compounds in wine is crucial for accurate analysis. While ethyl acetate itself adds desirable characteristics to wine, its levels need to be managed below perception thresholds to avoid negative sensory impacts and ensure accurate sulfur analysis in white wine.
Can ethyl acetate affect the calculation of ethanol yield?3 answersEthyl acetate can affect the calculation of ethanol yield. The thermodynamic analysis conducted by Andrade et al. showed that ethanol can be converted to ethyl acetate or acetaldehyde, with the two substances competing with each other for conversion. In the study by Inui et al., it was found that the selectivity to ethyl acetate increases with increasing reaction pressure, while ethanol conversion decreases. Jiu's research on vapor-liquid equilibrium data for ethyl acetate-ethanol-ionic liquid systems revealed that the presence of ionic liquids can alter the vapor-liquid equilibrium curves and increase the volatility of ethyl acetate relative to ethanol. Mevawala et al. investigated the thermodynamics of the ethanol-ethyl acetate cycle for hydrogen storage and found that the reaction can be shifted between hydrogenation and dehydrogenation, indicating that the yield of ethanol can be influenced by the reaction conditions. Finally, Luo et al. observed that the presence of acetic acid in the feed can decrease the conversion of ethyl acetate to ethanol, suggesting that the presence of impurities can affect the yield.

What is the optimal percentage of ethanol solvent for maximum flavonoid extraction efficiency?
4 answers
The optimal percentage of ethanol solvent for maximum flavonoid extraction efficiency varies depending on the plant material being studied. For example, in the extraction of flavonoids from C. maxima albedo, the optimal ethanol concentration was found to be 50% (v/v). On the other hand, in the extraction of flavonoids from elderberry, the optimal ethanol concentration was determined to be 40.9%. Additionally, in the extraction of flavonoids from Merremia mammosa root, a fixed-bed column using 70 wt% ethanol as a solvent was employed. Furthermore, for the extraction of total flavonoids from Dioscorea Nipponica leaf, an ethanol concentration of 70.5% was identified as optimal. Therefore, the optimal percentage of ethanol solvent for maximum flavonoid extraction efficiency can range from 40.9% to 70.5%, depending on the plant source.
