2-Ethyl-2-methyl-1,3-dioxolane (cas: 126-39-6) 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.Formula: C6H12O2

Preparation and catalytic activity of SO42-/TiO2-WO3 was written by Yang, Shui-Jin;Bai, Ai-Min;Yu, Xie-Qing;Sun, Ju-Tang. And the article was included in Youji Huaxue in 2004.Formula: C6H12O2 This article mentions the following:

A novel solid superacid catalyst, SO42-/TiO2-WO3, was prepared Its catalytic activity for twelve important ketals and acetals was measured with esterification of butyric acid with Bu alc. as probing reaction. The preparation conditions of SO42-/TiO2-WO3 have also been investigated, i.e., the mass ratio of the H2WO4 used in the compound is 12.5%, the calcining temperature is 580°, the calcining time is 3 h, and the soaked consistency of H2SO4 is 1.0 mol/L-1. Exptl. results showed that S042-/TiO2-WO3 is an excellent catalyst for the synthesis of twelve important ketals and acetals. The optimum reaction conditions are that the molar ratio of aldehyde/ketone to glycol is 1:1.5, the mass ratio of the catalyst used in the reactants is 0.5%, and the reaction time is 1.0 h. Under these conditions, the yield of 2-methyl-2-ethoxycarbonylmethyl-1,3-dioxolane is 78.7%, 2,4-dimethyl-2-ethoxycarbonylmethyl-1,3-dioxolane 83.0%, cyclohexanone ethylene ketal 85.9%, cyclohexanone 1,2-propanediol ketal 84.6%, butanone ethylene ketal 70.7%, butanone 1,2-propanediol ketal 88.3%, 2-propyl-1,3-dioxolane 80.6%, 4-methyl-2-propyl-1,3-dioxolane 79.6%, 2-isopropyl-1,3-dioxolane 64.2%, 4-methyl-2-isopropyl-1,3-dioxolane 83.3%, 2-phenyl-1,3-dioxolane 75.3%, 4-methyl-2-phenyl-1,3-dioxolane 95.1%, resp. In the experiment, the researchers used many compounds, for example, 2-Ethyl-2-methyl-1,3-dioxolane (cas: 126-39-6Formula: C6H12O2).
