Abstract

Ionic Liquids (ILs) are considered "green" solvents. They are used for a number of purposes in the field of science, among them more recently, the pre-treatment of lignocellulosic biomass. The description as an ecological solvent is due to the low vapor pressures and combustibility, besides being easily recovered and reused, they have received a lot of attention in recent years for representing an alternative to conventional solvents. Thus, the application of several ILs to obtain cellulose nanocrystals has been proposed due to the ability to remove amorphous regions such as hemicellulose and lignin, in order to maintain the crystalline regions of the chain. Nanocellulose, in turn, has attracted growing scientific and technological interest due to the great potential for use in areas such as biomedicine, cosmetics and materials industry, for example. Therefore, this article aims to review ionic liquids capable of producing cellulose at the nanoscale. The research was conducted by searching for publications carried out between the years 2015 and 2020 that highlight the most promising ILs for obtaining nanocellulose. The most studied LIs for this application are those derived from imidazolium, however, other types have shown to be effective in this process.

Keywords: nanocellulose, Ionic Liquids, biomass.
