WebApr 1, 2002 · However, there is a lack of knowledge of ester formation by wine LAB during MLF. Tentative evidence is available that ethyl esters, such as ethyl acetate, ethyl lactate, ethyl hexanoate and ethyl octanoate, are formed during MLF (Dittrich 1987; de Revel et al. 1999; Delaquis et al. 2000). This suggests that wine LAB possess the ability to ... WebMar 28, 2024 · alkyl lactate ester acrylates is reported for the first time. Kinetic experiments were conducted to demonstrate that Cu(0) wire-catalyzed single electron transfer-living radical polymerization (SET-LRP) in alcohols at 25 °C provides a green methodology for the LRP of this forgotten class of biobased monomers. The acrylic derivative of ethyl ...
