Esterification of dicarboxylic acids to diesters over Mn+-montmorillonite clay catalysts was written by Reddy, C. Ravindra;Iyengar, Pushpa;Nagendrappa, Gopalpur;Prakash, B. S. Jai. And the article was included in Catalysis Letters in 2005.Product Details of 1190-39-2 This article mentions the following:
Esterification of dicarboxylic acids with various alcs. and phenols in presence of metal exchanged montmorillonite clay catalyst (Mn+-mont; Mn+ = Al3+, Fe3+, Cr3+, Zn2+, Mn2+, and Ni2+) was studied. Among the catalysts used, Al3+-mont was found to be the most effective, as it gave good to excellent yields of esters under mild reaction conditions. The heterogeneous catalyst presented here can be regenerated and reused. All these features indicate the high potential of the reaction as “green chem.” process. In the experiment, the researchers used many compounds, for example, malonic acid dibutyl ester (cas: 1190-39-2Product Details of 1190-39-2).
malonic acid dibutyl ester (cas: 1190-39-2) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Product Details of 1190-39-2
