A Bronsted acidic, ionic liquid containing, heteropolyanion functionalized polysiloxane network I [R = OEt/H] was formed by self-condensation of dodecatungstophosphoric acid and a zwitterionic organosilane precursor II containing both imidazolinium and sulfonate groups. The resulting hybrid material POS-HPA-IL I was investigated as a catalyst for the selective esterification of dicarboxylic acids such as benzene-1,4-dicarboxylic acid, citric acid, citraconic acid, etc.. In the part of experimental materials, we found many familiar compounds, such as 3-(Methoxycarbonyl)benzoic acid(cas: 1877-71-0Recommanded Product: 1877-71-0)
3-(Methoxycarbonyl)benzoic acid(cas: 1877-71-0) belongs to esters. They are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils. They 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.Recommanded Product: 1877-71-0
