2-Methyl-2-ethoxycarbonylmethyl-1,3-dioxolane was synthesized by the reaction of Et acetylacetate with glycol with I2/PAn as the catalyst, and the effect of I2/PAn on the catalytic activity of ketal reaction as well as the effect of molar ratio of materials, catalyst usage and reaction time on product yield were studied. According to the results, I2/PAn is a good catalyst for synthesizing 2-methyl-2-ethoxycarbonylmethyl-1,3-dioxolane. The optimum reaction conditions were identified, i.e. n(Et acetylacetate):n(glycol) = 1:1.6, percentage of catalyst amount in total mass of reaction materials: 0.6%, water carrying agent: cyclohexane, and reaction time: 45 min. The yield of 2-methyl-2-ethoxycarbonylmethyl-1,3-dioxolane can reach 86.2% at above conditions. This study involved multiple reactions and reactants, such as Ethyl 2-(2-methyl-1,3-dioxolan-2-yl)acetate (cas: 6413-10-1Safety 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. 1,3-Benzodioxole can be synthesized from catechol with disubstituted halomethanes.Safety of Ethyl 2-(2-methyl-1,3-dioxolan-2-yl)acetate
