Abstract
Methods and compositions are provided for synthesizing ionic liquids from lignin. Methods and compositions are also provided for treating lignin with ionic liquids.
Claims13
An ionic liquid comprising at least one compound of the following formula:
- wherein each of the R groups of the nitrogen is independently selected from the group consisting of H, CH3, and CH2CH3;
- at least two of the R groups of the nitrogen are independently selected from the group consisting of CH3, and CH2CH3;
- R′, R″, and R′″ are independently selected from the group consisting of H, OH, and OCH3;
- R4 is selected from the group consisting of H, OH, and CH2OH;
- and
- X comprises an acid anion.
3 more elements
An ionic liquid prepared by
- contacting a starting material comprising lignin with a depolymerization agent to depolymerize the lignin and form a mixture of aldehyde containing compounds;
- contacting the mixture of aldehyde containing compounds with an amine under conditions suitable to convert the mixture of aldehyde containing compounds to a mixture of amine containing compounds;
- and
- contacting the mixture of amine containing compounds with a mineral acid under conditions suitable to form an ammonium salt, thereby preparing an ionic liquid.
