===== Organosolv =====
===== Organosolv (lignin hydrolysis) =====
Organosolv pretreatment is the process to extract lignin from lignocellulosic feedstocks with organic solvents or their aqueous solutions.
 
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">{{Cite journal|title=A comprehensive review on pre-treatment strategy for lignocellulosic food industry waste: Challenges and opportunities|year=2016-01-01|journal=Bioresource Technology|volume=199|page=92–102|doi=10.1016/j.biortech.2015.07.106|author=Amit K.
