The article was titled 《Synthesis, vibrational and thermal properties of new functionalized 1-(2-hydroxyethyl)-3-methylimidazolium dihydrogenophosphate ionic liquid》, and you may find the article in Journal of Molecular Structure.COA of Formula: C4H6N2 The information in the text is summarized as follows:
Very recently, the hydroxyl-functionalized ionic liquids have gained immense interest and were developed for a number of interesting applications. In this work and for the first time new hydroxyl-functionalized namely; 1-(hydroxyethyl)-3-methylimidazolium dihydrogenophosphate ionic liquid [EtOHMIM+][H2PO4-] was synthesized. The synthesis is based on an alkylation reaction of 1-methylimidazole followed by anion exchange. The obtained IL is characterized by 1H-NMR, 13C-NMR spectroscopy. Their exptl. vibrational spectroscopy have been investigated using IR and Raman spectroscopy, based on the IR (IR) and Raman spectroscopies results, complete vibrational assignments have been performed. Besides, thermal properties of this hydroxyl-functionalized IL were investigated by using following techniques, (i) thermogravimetric anal. (TGA) and derivative thermogravimetry (DTG) in the temperature range from 20 to 600°, (ii) differential scanning calorimetry (DSC) from-100° to 200°. The thermogravimetry anal. was coupled with mass spectrometry in order to assess the influence of anion on the measured property. In addition to this study using 1-Methyl-1H-imidazole, there are many other studies that have used 1-Methyl-1H-imidazole(cas: 616-47-7COA of Formula: C4H6N2) was used in this study.
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.COA of Formula: C4H6N2
