So far Fe-based ionic liquids have been extensively concerned in both fundamental studies and application fields. In the point of raw material differences for the preparation of Fe-based ionic liquids

the preparation process and phenomena of Fe-based ionic liquids in aqueous phase and air were studied systemically with different raw material mole ratios. A green technology of the recycling reuse of aqueous residual solution for the re-preparation of Fe-based ionic liquids with zero discharge was established. The possible transfer conditions of the Fe-based ionic liquids from different preparation raw materials with use of anhydrous ferric chloride and hexahydrated ferric chloride was explored

which can give some references for understanding and promoting the researches and applications of Fe-based ionic lqiuds.
