Abstract

Provided are sugar-based compounds, method so making such compounds, gels comprising such compounds, methods of making gels, methods of using such compounds for containing spill of a hydrocarbon, and methods for reclaiming solvent from gels comprising such compounds.

First claim

We claim:

1. A compound having the Formula:

wherein R 1 and R 2 are C 1 to C 6 alkyl.

2. A compound having the Formula:

wherein R 1 is C 1 to C 6 alkyl and R 2 is hydrogen.

3. The compound as claimed in claim 1 , wherein R 1 and R 2 are C 1 alkyl.

4. The compound as claimed in claim 1 , wherein R 1 and R 2 are C 2 alkyl.

5. A method of preparing the compound as claimed in claim 1 , the method comprises the steps of:
mixing a non-polar solvent and a polar solvent to obtain a first solution, the non-polar solvent being selected from a group consisting of cyclohexane, hexane and heptane, and the polar solvent being selected from a group consisting of methanol, ethanol, propanol and isopropanol;
contacting sorbitol and a reagent to obtain a second solution, the reagent being the reagent selected from a group consisting of p-TsOH and dodecyl benzene sulfonic acid;
adding the second solution to the first solution to obtain a solution and reacting the solution with a second reactant to obtain the compound, the second reactant being selected from a group consisting of benzaldehyde, acetophenone, and phenyl ethyl ketone.

6. A gel comprising a compound as claimed in claim 1 and a solvent.

7. The gel as claimed in claim 6 , wherein the solvent is selected from water, an organic solvent, or mixtures thereof.

8. A method for producing a gel comprising contacting he compound as claimed in claim 1 with a solvent.

9. The method as claimed in claim 8 wherein the solvent is selected from water, an organic solvent, or mixtures thereof.

10. The method of claim 8 , wherein the solvent is a hydrocarbon.

11. The method of claim 8 , wherein the solvent comprises a mixture of a hydrocarbon and water.

12. A method of containing the spill of a hydrocarbon, the method comprising contacting the hydrocarbon with the compound as claimed in claim 1 to obtain a gel.

13. A method of reclaiming solvent and a compound as claimed in claim 1 from a gel made of the compound and the solvent.
