Metal-containing TUD-1 mesoporous silicates as versatile solid acid catalysts for the conversion of bio-based compounds into valuable chemicals was written by Li, Li;Cani, Damiano;Pescarmona, Paolo P.. And the article was included in Inorganica Chimica Acta in 2015.Category: dioxole This article mentions the following:

Three-dimensional mesoporous silicates of the TUD-1 family were synthesized with different metals (Zr, Hf and Sn) incorporated in the framework of the material. The mesoporosity of the prepared TUD-1s was confirmed by x-ray diffraction (x-ray diffraction), nitrogen physisorption and TEM. The incorporation of the metals in the silicate structure was investigated by FT-IR and UV-Vis spectroscopy. All three TUD-1 materials present a combination of Lewis and mild Bronsted acid sites, as determined by TPD-FT-IR of pyridine adsorption. The metal-containing TUD-1 materials were tested as solid acid catalysts for the conversion of three bio-based compounds into valuable chem. products. In the conversion of dihydroxyacetone into Et lactate, complete selectivity towards the desired lactate product was achieved with Zr-, Hf- and Sn-TUD-1. The three heterogeneous catalysts displayed similar activity, with Hf-TUD-1 reaching the highest conversion and metal-based turnover number Sn-TUD-1 also displayed high activity and selectivity in two acetalization reactions, i.e. the synthesis of solketal from acetone and glycerol and the reaction of vanillin with propylene glycol. The catalytic performance of these TUD-1 materials is ascribed to the high accessibility of their active sites and to the suitable combination of acid sites. The catalysts were successfully reused in consecutive runs and did not suffer from leaching. In the experiment, the researchers used many compounds, for example, 2-Methoxy-4-(4-methyl-1,3-dioxolan-2-yl)phenol (cas: 68527-74-2Category: dioxole).

2-Methoxy-4-(4-methyl-1,3-dioxolan-2-yl)phenol (cas: 68527-74-2) 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.Category: dioxole

MOR zeolite supported Bronsted acidic ionic liquid: an efficient and recyclable heterogeneous catalyst for ketalization was written by Li, Zhang-Min;Zhou, Yan;Tao, Duan-Jian;Huang, Wei;Chen, Xiang-Shu;Yang, Zhen. And the article was included in RSC Advances in 2014.Product Details of 177-10-6 This article mentions the following:

In order to widen the application of ionic liquids as efficient and renewable heterogeneous catalysts, supported ionic liquids (SILs) have received considerable attention. A novel heterogeneous catalyst MOR zeolite supported Bronsted acidic ionic liquid (BAIL@MOR) was therefore prepared, characterized and applied in the ketalization reaction. The influences of reaction temperature, time, and catalyst loading have also been investigated in detail. Combined characterization results of XRD, FT-IR, SEM, TG-DTG and N₂ adsorption-desorption suggested that the BAIL [CPES-BSIM][HSO₄] was successfully immobilized on the surface of MOR zeolite by covalent bonds. Moreover, the catalytic performance tests demonstrated that the catalyst BAIL@MOR exhibited excellent catalytic activities in the ketalization of cyclohexanone with glycol, 1,2-propylene glycol and 1,3-butylene glycol under mild reaction conditions, as comparable with the homogeneous catalysis of the precursors [BSmim][HSO₄] and H₂SO₄. In addition, the catalyst BAIL@MOR was also found to be reusable five times without a significant loss of its catalytic activity. Thus, the heterogeneous catalyst BAIL@MOR can act as a promising candidate for the ketalization reaction.
