Abstract

A method for synthesizing a hydrophobic deep eutectic solvent (DES) using one or more lignin-derived compounds is provided.

Claims (25)

1. A method for synthesizing a hydrophobic deep eutectic solvent, comprising:

mixing a first compound with a second compound to create a mixture;

heating the mixture; and

stirring the mixture until a homogenous liquid is obtained;

wherein the first compound and the second compound are not the same compound;

wherein the first compound is menthol, thymol, decanoic acid, or 2,6-dimethoxyphenol; and

wherein the second compound is 2,6-dimethoxyphenol, phenol, 1-pheylethanol, guaiacol, vanillin, or 4-hydroxybenzyl alcohol.

2. The method according to claim 1 , wherein the first compound and the second compound are each phenolic.

3. The method according to claim 1 , wherein heating the mixture comprises increasing the temperature of the mixture to a value within a range of about 60° C. to about 100° C.

4. The method according to claim 1 , wherein the first compound is menthol and the second compound is 2,6-dimethoxyphenol.

5. The method according to claim 1 , wherein the first compound is menthol and the second compound is phenol.

6. The method according to claim 1 , wherein the first compound is menthol, and the second compound is 1-phenylethanol.

7. The method according to claim 1 , wherein the first compound is menthol and the second compound is guaiacol.

8. The method according to claim 1 , wherein the first compound is thymol and the second compound is vanillin.

9. The method according to claim 1 , wherein the first compound is thymol and the second compound is 2,6-dimethoxyphenol.

10. The method according to claim 1 , wherein the first compound is thymol and the second compound is phenol.

11. The method according to claim 1 , wherein the first compound is thymol and the second compound is guaiacol.

12. The method according to claim 1 , wherein the first compound is decanoic acid and the second compound is 2,6-dimethoxyphenol.

13. The method according to claim 1 , wherein the first compound is decanoic acid and the second compound is phenol.

14. The method according to claim 1 , wherein the first compound is decanoic acid and the second compound is guaiacol.

15. The method according to claim 1 , wherein the first compound is decanoic acid and the second compound is 1-phenylethanol.

16. The method according to claim 1 , wherein the first compound is 2,6-dimethoxyphenol and the second compound is 4-hydroxybenzyl alcohol.

17. The method according to claim 1 , wherein the first compound is 2,6-dimethoxyphenol and the second compound is vanillin.

18. The method according to claim 1 , wherein the first compound is 2,6-dimethoxyphenol and the second compound is phenol.

19. The method of claim 1 , wherein the first compound and the second compound are mixed in a molar ratio of 1:1, 1:2, 2:1, 3:1, 4:1, or 5:1.
