Zeolitic imidazolate framework (ZIF‐8, Zn(2‐meIm)2) and composites based on ZIF‐8 and alumina nanofibers (NafenTM), i.e. ZIF‐8/Nafen, were demonstrated to be efficient heterogeneous catalysts for the reaction of methanol with propylene oxide to produce propylene glycol methyl ether (PGME), which is a member of the family of glycol ether solvents used for a wide variety of consumer products and industrial applications. Both the reaction rate and the selectivity toward PGME were found to decrease with increasing crystal size of the ZIF‐8 material, which was related to the change in the number of basic sites and their accessibility. The investigation of ZIF‐8/Nafen composites revealed the dependence of their catalytic performance on the amount of the ZIF‐8 component. In particular, the activity was affected by the crystal size of the ZIF‐8 material and the nature of acid‐base sites in its framework.

“…The yields of 1-MP were 95−96% and 96−97% in the presence of IL/bentonite and IL/SBA-5, respectively. 13 The use of mesoporous silica MCM-41 as a support for ILs was proposed. 14 Thus, application of cetyltrimethylammonium hydroxide ([CTA]OH) encapsulated in MCM-41 has led to a yield of 92% with 92−93.5% selectivity toward 1-MP at 110 °C.…”

“…Several recent studies have shown that the reaction temperature could be reduced by the application of nitrogen containing compounds. Liang et al showed that the reaction temperature can be decreased to 110–120 °C in the presence of the immobilized ionic liquid (IL) 1,1,3,3-tetramethylguanidium lactate on bentonite and SBA-15 (IL/support). The yields of 1-MP were 95–96% and 96–97% in the presence of IL/bentonite and IL/SBA-5, respectively .…”

Herein, we demonstrated that zinc zeolitic imidazolate frameworks (ZIFs) based on 2-methylimidazole (ZIF-8) and 2-ethylimidazole (MAF-5 or ZIF-14) linkers could be used as effective heterogeneous catalysts for catalytic synthesis of 1-methoxy-2-propanol (1-MP) that is widely used in industry due to its negligible toxicity as an ecofriendly solvent and as an intermediate for the synthesis of different chemicals. Application of these materials decreased the reaction temperature to 110 °C. 1-MP was found to be the major product, with 92.1–93.8% selectivity. The activity of MAF-5 was higher than that of ZIF-8. This difference can be explained by the high basicity of MAF-5. MAF-5 and ZIF-8 materials showed good reusability for 5 cycles in catalysis, which indicates their high potential for catalytic applications. Compared with reported catalysts, the studied ZIFs, especially MAF-5, showed not only the highest conversion of PO but also the highest selectivity for 1-MP under similar reaction conditions

Ionic liquids (ILs) have attracted much attention due to their unique properties and wide application potential in a variety of fields. The unusual properties of ILs provide numerous opportunities to design and prepare arious advanced materials, including highly efficient catalysts. In recent years, synthesis of different kinds of catalytic materials and their applications in chemical reactions have been studied extensively and have become a very interesting area. Herein, we present a review on the synthesis of catalytic materials using ILs as the media and/or functional components; the important and widely investigated topics are discussed, including mainly metal nanocatalysts/IL, functional IL/support, metals or metal oxides/IL/support, polymeric ILs (PILs) catalysts, and the performances of catalytic systems are highlighted. An outlook for this interesting area is also given at the end of the article.
