説明

Ionic liquids (ILs) act as solvent and catalyst of ammonia borane (AB). In this study, basic properties of AB-imidazolium-based IL solutions and their dehydrogenation properties have been studied. Solubility of AB in ILs showed 32〜35 wt% and 30 wt% AB-IL have densities of 〜0.9 g/cm3, viscosities of 150〜200 cP, and glass transition appeared <-50 ℃. AB-ILs desorbed <0.08 eq.H_2 in 2 weeks at RT and 〜2 eq. H_2 below 130 ℃ with limited impurity emissions. No reaction between AB and ILs occurs upon dehydrogenation, though their products were solid solution.
