For the purpose of calculate and compare the variation in thermal storage d., data for the thermal stability, heat capacity, and d. properties of equimolar binary mixtures of 1-octyl-3-methylimidazolium and 1-octyl-2,3-dimethylimidazolium based ionic liquids have been measured. Preliminary anal. of fifteen mixtures obtained from six ionic liquid provide evidence that certain mixtures increase its heat capacity and hence its thermal storage d., offering a viable alternative to materials currently used in solar energy storage. In the part of experimental materials, we found many familiar compounds, such as 1-Methyl-1H-imidazole(cas: 616-47-7Formula: C4H6N2)
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.Formula: C4H6N2
