Abstract

The invention relates to the compounds of formula (I),in which R1 and R2 represent a linear, branched or cyclic, saturated or unsaturated hydrocarbon group, comprising 1 to 6 carbon atoms, wherein the sum of the carbon atoms of the groups R1 and R2 is from 2 to 7; A represents a chain of one or a plurality of units of ethylene oxide, propylene oxide, butylene oxide and mixtures thereof; and n is an integer between 1 and 100 inclusive. The invention also relates to mineral or organic salts thereof; the use of the compounds of formula (I) and/or of one of the salts thereof as a surfactant, a wetting agent, a detergent, an emulsifying agent, a dispersant, a corrosion inhibitor, and the like; and to compositions comprising at least one compound of formula (I) and/or of one of the salts thereof.

First claim

The invention claimed is:

1. A compound of formula (I) below:

wherein:
R 1 and R 2 , together with the carbon atom that bears R 1 and R 2 forms a 2-octyl radical;
A represents a sequence of one or more units chosen from ethylene oxide, propylene oxide and butylene oxide units, and mixtures thereof; and
n is an integer between, limits inclusive, 1 and 100.

2. The compound as claimed in claim 1 , in the form of a salt with an alkali metal cation, and alkaline-earth metal cation, a metal cation or with an organic compound.

3. The compound as claimed in claim 1 , wherein n is between, limits inclusive, 1 and 75.

4. The compound as claimed in claim 1 , wherein n is between, limits inclusive, 1 and 50.

5. The compound as claimed in claim 1 , wherein n ranges from 3 to 15.

6. A salt of the compound as claimed in claim 1 , corresponding to formula (II) below:

wherein:
M x+ represents a cationic group bearing at least one cation chosen from an ammonium cation, a metal cation, a nitrogen cation, a boron cation and a phosphorus cation, and
x is an integer ranging from 1 to 7.
