In this work, we demonstrate a simple and atom-economic method for preparation of a novel hydrophobic ionic liquid (IL) from hydrophilic ILs and its characterization data are disclosed. The simple preparation route also provides opportunities for removal/recovery of the IL during cellulose dissolution.
