2144-40-3, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 2144-40-3, molcular formula is C6H12O3, introducing its new discovery.
NOVEL METHOD FOR PREPARING HIGHLY TRANSPARENT AND HIGHLY HEAT-RESISTANT POLYCARBONATE ESTER
The present invention relates to a method for preparing a bio-based polycarbonate ester, the method comprising the steps of: (1) preparing a compound represented by chemical formula 3 by converting a compound represented by chemical formula 2 into an intermediate reactant having an easily detachable functional group, followed by a nucleophilic reaction with phenol; and (2) preparing a compound including a repeat unit represented by chemical formula 1 by a polycarbonate melt condensation polymerization of the compound represented by chemical formula 3, prepared in step (1), a compound represented by chemical formula 4, and 1,4:3,6-dianhydrohexitol. The bio-based polycarbonate ester according to the present invention can regulate merits and demerits of physical properties obtained from each repeat unit, and can be favorably used for various uses due to high degrees of transparency and heat resistance thereof.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, 2144-40-3, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 2144-40-3
