In 2019,Polymers (Basel, Switzerland) included an article by Kujawa, Joanna; Rynkowska, Edyta; Fatyeyeva, Kateryna; Knozowska, Katarzyna; Wolan, Andrzej; Dzieszkowski, Krzysztof; Li, Guoqiang; Kujawski, Wojciech. Reference of 1-Methyl-1H-imidazole. The article was titled 《Preparation and characterization of cellulose acetate propionate films functionalized with reactive ionic liquids》. The information in the text is summarized as follows:
The 1-(1,3-diethoxy-1,3-dioxopropan-2-ylo)-3-methylimidazolium bromide (RIL1_Br), 1-(2-etoxy-2 -oxoethyl)-3-methylimidazolium bromide (RIL2_Br), 1-(2-etoxy-2-oxoethyl)-3 -methylimidazolium tetrafluoroborate (RIL3_BF4) ionic liquids were synthesized. Subsequently, the dense cellulose acetate propionate (CAP)-based materials containing from 9 to 28.6 weight% of these reactive ionic liquids were elaborated. Reactive ionic liquids (RILs) were immobilized in CAP as a result of the transesterification reaction. The yield of this reaction was over 90% with respect to the used RIL. The physicochem. properties of resultant films were studied using NMR (NMR), SEM, energy dispersive X-ray (EDX), at. force microscopy (AFM), and thermogravimetric anal. (TGA). The RIL incorporation influenced the morphol. of films by increasing their surface roughness with the rise of RIL content. The thermal stability of CAP-based membranes was dependent on the nature of the ionic liquid Nevertheless, it was proven that CAP films containing RILs were stable up to 120-150°C. Transport properties were characterized by water permeation tests. It was found that the type and the amount of the ionic liquid in the CAP matrix substantially influenced the transport properties of the prepared hybrid materials. In the experiment, the researchers used 1-Methyl-1H-imidazole(cas: 616-47-7Reference of 1-Methyl-1H-imidazole)
1-Methyl-1H-imidazole(cas: 616-47-7) is actively involved in removing acid during the production of diethoxyphenylphosphine. It is used as an intermediate in organic synthesis.Reference of 1-Methyl-1H-imidazole
