Abstract

The present invention relates to compounds derivable from the esterification of a fatty alcohol and furoic acid according to Formula (I). The present invention also relates to the use of said compounds as surfactants, compositions comprising said compounds, and the manufacture of said compounds.

Claims (24)

1. A compound of Formula (Ia):

wherein X is a cation; and

R 2 is an acyclic C 8 to C 18 aliphatic group.

2. The compound according to claim 1 , wherein X is an alkali metal cation.

3. The compound according to claim 1 , wherein X is a sodium cation or a potassium cation.

4. The compound according to claim 1 , wherein X is a sodium cation.

5. The compound according to claim 1 , wherein R 2 is a straight-chain C 8 to C 18 aliphatic group.

6. The compound according to claim 5 , wherein R 2 is a straight-chain C 8 to C 18 alkyl group.

7. The compound according to claim 6 , wherein R 2 is a straight-chain C 8 , C 12 or C 16 alkyl group.

8. The compound according to claim 5 , wherein R 2 is an unsaturated straight-chain C 8 to C 18 aliphatic group.

9. The compound according to claim 1 , having a structure of:

10. A surfactant, comprising a compound according to claim 1 .

11. A composition comprising a compound of claim 1 , wherein the composition is a detergent composition, a personal care composition, an oil recovery composition, a pharmaceutical composition, a drug delivery composition, an agricultural composition a coating composition, or a paint composition.

12. A composition comprising a mixture of two or more compounds of claim 1 .

13. The composition according to claim 12 , comprising a compound of claim 1 wherein R 2 is an acyclic C 8 aliphatic and a compound of claim 1 wherein R 2 is an acyclic C 12 or C 16 aliphatic.

14. A process for manufacturing a compound of Formula (Ia):

comprising the steps of:

a) contacting a compound of Formula (II):

with a sulfonation agent; and

b) adding a base to form the compound of Formula (Ia),

wherein X and R 2 are as defined in claim 1 .

15. A composition comprising a compound of claim 1 and sodium dodecyl sulfate.

16. The compound according to claim 1 , wherein R 2 is a branched C 8 to C 18 alkyl group.

17. The compound according to claim 2 , wherein the alkali metal cation is a sodium cation, a potassium cation, a lithium cation, a calcium cation, a magnesium cation, or an ammonium cation.
