And the article was included in Journal of Saudi Chemical Society in 2011.Application In Synthesis of Ethyl 2-(2-methyl-1,3-dioxolan-2-yl)acetate The following contents are mentioned in the article:
Fructone [synthetic aroma, apple ketal 2,4-dimethyl-2-ethylacetoacetate-1,3-dioxolane, 2-methyl-1,3-dioxolane-2-acetic acid Et ester] was prepared from Et acetoacetate (EAA) with 1,2-propanediol (PPO) catalyzed by aluminum sulfate in the presence of an ionic liquid A combination of aluminum sulfate and [bmim]BF4 exhibited good catalytic activity and high selectivity towards fructone. A synergistic effect of aluminum sulfate and [bmim]BF4 on the acetalization (ketalization) was observed After the reaction was complete, the products could be separated from the reaction mixture extraction with di-Me ether and the catalyst and ionic liquid could be directly recycled several times without a significant decrease in the activity and selectivity towards fructone. This study involved multiple reactions and reactants, such as Ethyl 2-(2-methyl-1,3-dioxolan-2-yl)acetate (cas: 6413-10-1Application In Synthesis of Ethyl 2-(2-methyl-1,3-dioxolan-2-yl)acetate).
Ethyl 2-(2-methyl-1,3-dioxolan-2-yl)acetate (cas: 6413-10-1) 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.Application In Synthesis of Ethyl 2-(2-methyl-1,3-dioxolan-2-yl)acetate
