Catalytic synthesis of benzaldehyde 1, 2-propylene acetalization by the catalyst of polyaniline doped with copper chloride was written by He, Miao;Zhou, Haixia;Liu, Chunsheng;Luo, Genxiang. And the article was included in Huaxue Yanjiu Yu Yingyong in 2006.Recommanded Product: 126-39-6 This article mentions the following:
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%. 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
