Metal nanoparticles assisted amine catalyzed transesterification under ambient conditions was written by Rathore, Puran Singh;Advani, Jacky;Rathore, Sonika;Thakore, Sonal. And the article was included in Journal of Molecular Catalysis A: Chemical in 2013.Name: malonic acid dibutyl ester This article mentions the following:
Ethylenediamine provides excellent activity under ambient conditions when assisted by metal nanoparticles for the transesterification of higher to lower esters and vice versa. This is the first report on room temperature conversion of di-Et malonate to di-Me malonate using this novel catalytic system. The nanoparticles were successfully recycled up to 24 cycles (although with an increase in reaction time) with no compromise in the yield. Various primary alcs. were used for transesterification. The scope was extended to aliphatic, heterocyclic and aromatic esters with various functional groups. In the experiment, the researchers used many compounds, for example, malonic acid dibutyl ester (cas: 1190-39-2Name: malonic acid dibutyl ester).
malonic acid dibutyl ester (cas: 1190-39-2) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Name: malonic acid dibutyl ester
