Good source for IL treatment of lignocellulosic biomass -->'''Ionic liquids''' are organic salts that are liquid at room temperature. Because they are salts, they show no volatility. Moreover, they show a high thermal stability. Together this allows for them to be used as green solvents as alternatives to volatile organic compounds. These properties can be used in the pre-treatment of lignocellulosic material by dissolving the material and separating the lignin.</onlyinclude><ref name=":0">{{Cite journal|title=Ionic liquid-mediated selective extraction of lignin from wood leading to enhanced enzymatic cellulose hydrolysis|year=2009-04-01|author=Sang Hyun Lee, Thomas V.

It seems mostly the biomass is dissolved to then allow for more efficient hydrolysis (enzymatic and others) into lignin, cellulose and other byproducts. --> | ||

The final product of the process depends on the exact combination of technologies. Generally, a large part of the lignin can be extracted from lignocellulosic material. The resulting lignin can be one of the products, the other begin the remaining lignocellulosic material, where the cellulose is more easily available for further processing. | The final product of the process depends on the exact combination of technologies.
