Abstract
The present invention provides for novel protic ionic liquids (PIL) or phosphate-based ionic liquid (PBIL) useful for lignocellulosic processing described herein. The novel protic ionic liquids are capable of pretreatment of lignocellulosic biomass over a wide range of pH.
Claims15
A solution or slurry comprising:
- (a) a lignocellulosic biomass, (b) a protic ionic liquid (PIL), a phosphate-based ionic liquid (PBIL), or a mixture thereof, and (c) optionally a cellulase.
A method to produce a biofuel from a biomass, the method comprising:
- (a) introducing (i) a protic ionic liquid (PIL) comprising the following structure:
- [α′][β′], wherein α′ is a protic substituted primary, secondary, tertiary, or quaternary alkylamine, or a mixture thereof, and β′ is any suitable anion, (ii) a phosphate-based ionic liquid (PBIL), or (iii) a mixture thereof, to a lignocellulosic biomass to produce a solution or slurry.
