Synthesis of ketals of ethyl acetoacetate catalyzed by activated carbon supported SnCl4·5H2O under microwave irradiation was written by Zhang, Min;Yuan, Lin;Yuan, Xianyou. And the article was included in Guangzhou Huaxue in 2007.COA of Formula: C8H14O4 The following contents are mentioned in the article:
Two ketals were synthesized from Et acetoacetate with ethylene glycol and 1,2-propanediol using activated carbon supported SnCl4·5H2O (SnCl4·5H2O/C) as catalysts without solvent under microwave irradiation Under the optimum reaction conditions (SnCl4·5H2O/C (loaded amount 20%) 0.1 g), Et acetoacetate 5 mL, ethylene glycol 6 mL, microwave power 600 W, microwave irradiation time 2.5 mm, the yield of ketal was 81.6%. The products were characterized by IR. This study involved multiple reactions and reactants, such as Ethyl 2-(2-methyl-1,3-dioxolan-2-yl)acetate (cas: 6413-10-1COA of Formula: C8H14O4).
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. 1,3-Benzodioxole can be synthesized from catechol with disubstituted halomethanes.COA of Formula: C8H14O4
