1,3-Dimethylimidazolium nitrate [DMIM][NO3] stands out as a novel solvent within the imidazole-based class of ionic liquids (ILs). 1,3-Dimethylimidazolium is a five-membered ring aromatic cation composed of two nitrogen atoms and three carbon atoms, with methyl groups substituted at positions 1 and 3 of the nitrogen atoms, respectively. The nitrate anion is a poly-ion species characterized by one nitrogen atom and three oxygen atoms. This combination of cationic and anionic components resolves facilitating several applications in chemical synthesis, catalysis, and materials science.
Thermodynamic properties of this compound are not available due to its ionic nature that exhibits fast and often uncontrollable chemical decomposition, determining its thermodynamic parameters represents a complex endeavor. Crystallographic studies have provided insights into its crystal structures. Critical thermodynamic characteristics were determined including its melting (Tm) and decomposition temperatures (Td).[1] Some experimental studies were carried out to better understand the thermal stability of close-class compounds.[2],[3] Differential scanning calorimetry and thermogravimetric analysis were performed to understand thermal decomposition kinetics.[4] Computational methods contributed to a deeper understanding of its behavior under various thermodynamic conditions.[5] Its unique chemical structure and properties make this compound a promising candidate for various applications from green chemistry to advanced materials processing.
