Synthesis of cyclohexanone ethylene ketal catalyzed by Keggin-type Ni/Cu/2,2′-H2 biim-tungstosilicates was written by Zhu, Zai-ming;Wang, Yu;Yu, Zhan-jun;Wang, Qiu-xue;Du, Jing;Su, Fang. And the article was included in Yingyong Huagong in 2015.Name: 1,4-Dioxaspiro[4.5]decane This article mentions the following:
A series of Keggin-type Ni/Cu/H2biim-tungstosilicates (H2 biim = 2,2′-biimidazole) were synthesized with the parent tungstosilicic acid as a reactant and H2 biim, Ni2+/Cu2+ and their complexes as raw materials by a direct precipitation method. They were characterized by single crystal XRD, IR and elemental anal. The acid-catalyzed synthesis of cyclohexanone ethylene ketal by the reaction of cyclohexanone with ethylene glycol was selected as a model reaction. The catalytic activities of these tungstosilicates were investigated. The results show that the introduction of large cation reduced the POM’s solubility, and the catalysts can be recycled and reused, so that their utilization can be improved. Moreover, the catalytic activities of these heterogeneous catalysts were almost unchanged after three cycles. In the experiment, the researchers used many compounds, for example, 1,4-Dioxaspiro[4.5]decane (cas: 177-10-6Name: 1,4-Dioxaspiro[4.5]decane).
1,4-Dioxaspiro[4.5]decane (cas: 177-10-6) 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. Dioxole functionalized metal-organic frameworks have also been recently reported.Name: 1,4-Dioxaspiro[4.5]decane
