Preparation of SO₄^2-/TiO₂-MoO₃ solid superacid and its catalytic activity in acetalation and ketalation was written by Yang, Shuijin;Liang, Yongguang;Yu, Xieqing;Sun, Jutang. And the article was included in Chinese Journal of Chemical Engineering in 2005.Recommanded Product: 126-39-6 This article mentions the following:

The SO₄^2-/TiO₂-MoO₃ solid superacid was prepared and its catalytic activity under different synthetic conditions was examined with esterification of n-butanoic acid and Bu alc. as probing reaction. Optimum conditions for catalyst preparation were determined, i.e., the mass ratio of MoO₃ is 25%, the calcination temperature 450°, and the soaked consistency of H₂SO₄ is 0.5 mol·L^-1. The superacid catalyst was evaluated in the preparation of six ketals and acetals. Under molar ratio of aldehyde/ketone to glycol 1:1.5, mass ratio of catalyst to reactants of 0.5%, and reaction time of 1.0 h, the yield of ketals and acetals was up to 63.2%. The catalyst can be easily recovered and reused. In the experiment, the researchers used many compounds, for example, 2-Ethyl-2-methyl-1,3-dioxolane (cas: 126-39-6Recommanded Product: 126-39-6).

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.Recommanded Product: 126-39-6

A new environmentally friendly catalyst, polyaniline-copper dichloride (PAn-CuCl₂) was prepared Benzaldehyde acetal was synthesized from benzaldehyde and 1,2-propanediol . in the presence of this copper chloride-doped polyaniline catalyst. Factors influencing the product yield were discussed and the optimum conditions were found. Exptl. result showed that polyaniline doped with copper chloride is an excellent catalyst. With n(benzaldehyde)/n(1,2-propanediol) = 1/1.5, w(polyaniline-doped with copper chloride) = 0.98%, cyclohexane 14 mL and reaction time 2.0 h, yield of benzaldehyde 1,2-propylene acetal was 91%.
