Effect of polymer matrices of gels bearing a sulfo group on their catalytic properties for acetalization of glycerol to solketal and esterification of oleic acid to ethyl oleate was written by Tokuyama, Hideaki;Ohno, Hiroki;Fujita, Tara. And the article was included in Reactive & Functional Polymers in 2021.Product Details of 100-79-8 This article mentions the following:
A novel type of copolymer gel bearing the sulfo group was developed as a heterogeneous acid catalyst for the solvent free acetalization of glycerol with acetone to form a desirable solketal, as well as the solvent free esterification of oleic acid with ethanol to form Et oleate as a biodiesel fuel. The copolymer gels were synthesized by the copolymerization of a primary monomer (ethoxy diethyleneglycol acrylate (EDGA), N-isopropylacrylamide (NIPA), etc.) with 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS). The copolymer gels, such as EDGA-co-AMPS gel and NIPA-co-AMPS gel, successfully catalyzed both reactions with a higher reaction rate than those of AMPS gel and the conventional sulfonic ion exchange resin (Amberlyst). According to Le Chatelier’s principle, if a gel catalyst absorbs reactants well, and expels or poorly absorbs products, the apparent rate of the reaction occurring within the gel is enhanced. This hypothesis was examined by analyzing the solution absorptions of these gels and their reaction rates, including Eley-Rideal kinetic anal. In the experiment, the researchers used many compounds, for example, (2,2-Dimethyl-1,3-dioxolan-4-yl)methanol (cas: 100-79-8Product Details of 100-79-8).
(2,2-Dimethyl-1,3-dioxolan-4-yl)methanol (cas: 100-79-8) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. Although benzodioxole is not particularly important, many related compounds containing the methylenedioxyphenyl group are bioactive, and thus are found in pesticides and pharmaceuticals.Product Details of 100-79-8
