General description

1-Ethyl-3-methylimidazolium acetate, an aprotic imidazolium room-temperature ionic liquid, is a cellulosic solvent. The pretreatment of sugarcane bagasse with [Emim][Ac] leads to the formation of glucose via enzymatic saccharification.

1-Ethyl-3-methylimidazolium acetate is a catalyst that can be used to perform the acid-free cellulose acetylation process.

Application

1-Ethyl-3-methylimidazolium acetate has been used in the preparation of ionic liquid ferrofluid (ILF).
