Abstract

The invention concerns new quaternary ammonium compounds with surfactant properties and improved biodegradability.

First claim

The invention claimed is:

1 . An ionic compound of general formula I

wherein
A is a tetravalent linker A-5

Q 1 to Q 4 , which may be identical or different from each other, are selected from the group consisting of R and X,
wherein R, which may be the same or different at each occurrence, is a C 5 -C 27 aliphatic group, m, m′, m″ and m′″ are 0, k″″ is 0 and X, which may be the same or different at each occurrence, is represented by formula II

wherein Z 1 , Z 2 and Z 3 , which may be the same or different, are O, S or NH,
Y is a divalent C 1 -C 6 aliphatic radical,
R′, R″ and R′″, which may be the same or different, are hydrogen or a C 1 to C 4 alkyl group,
n and n′ are 0 or 1 with the sum of n+n′ being 1 or 2,
wherein two of substituents Q 1 to Q 4 are X with each carbon atom of linker A carrying one group X and one group R wherein X and R might be the same or different at each occurrence.

2 . The compound in accordance with claim 1 wherein n+n′ is 1.

3 . The compound in accordance with claim 1 wherein n+n′ is 2.

4 . The compound in accordance with claim 1 , wherein n′ is 1 and Y is a C 2 -C 6 aliphatic group.

5 . The compound in accordance with claim 1 wherein in groups X, n is 1, n′ is 0, and Y is CH 2 .

6 . An electroneutral compound of general formula (III)

wherein
A is a tetravalent linker A-5,

Q 1 to Q 4 are identical or different from each other and are selected from the group consisting of R and X,
wherein R, which may be the same or different at each occurrence, is a C 5 -C 27 aliphatic group, m, m′, m″ and m′″ are 0, k″″ is 0, and X, which may be the same or different at each occurrence, is represented by formula II

wherein Z 1 , Z 2 and Z 3 , which may be the same or different, are O, S or NH,
Y is a divalent C 1 -C 6 aliphatic radical,
R′, R″ and R′″, which may be the same or different, are hydrogen or a C 1 to C 4 alkyl group,
n and n′ are 0 or 1 with the sum of n+n′ being 1 or 2,
wherein two of substituents Q 1 to Q 4 are X with each carbon atom of linker A carrying one group X and one group R wherein X and R might be the same or different at each occurrence,
W is an anion or an anionic group bearing w negative charges and r is the number of substituents Q 1 to Q 4 which are represented by a group X.
