In an '''organosolv hydrolysis''' organic solvents are added to the process, usually performed at high temperatures (100-250 °C). This can be combined with a catalyst such as HCl or H<sub>2</sub>SO<sub>4</sub>.<ref name=":2" /> For example, in '''acid-acetone''' pre-treatment biowaste is treated with an acid such as phophoric acid and then mixed with pre-cooled acetone.<ref name=":0" /> | In an '''organosolv hydrolysis''' organic solvents are added to the process, usually performed at high temperatures (100-250 °C).

Ionic liquids are '''solvents''' that can be used for biomass pretreatment, fractionation, and dissolution. During IL pretreatment, a cellulose-rich fraction can be generated through the degradation and removal of a large portion of lignin and hemicellulose <ref>{{Cite web|Author=Moyer, P., Kim, K., Abdoulmoumine, N. et al.|year=2018|title=Structural changes in lignocellulosic biomass during activation with ionic liquids comprising 3-methylimidazolium cations and carboxylate anions|e-pub date=27/09/2018|date accessed=06/12/2021|url=https://biotechnologyforbiofuels.biomedcentral.com/articles/10.1186/s13068-018-1263-0}}</ref> | Ionic liquids are '''solvents''' that can be used for biomass pretreatment, fractionation, and dissolution.
