Abstract
The invention relates to compounds of formula (I), in which R1, R2, A and n are as defined. 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.

A method of utilizing a compound of formula (I) as a surfactant, low-foaming surfactant, wetting agent, foaming agent, hydrotrope, detergent, solvent, reactive solvent, coalescer, compatibilizer, emulsifying agent, dispersant, chemical intermediary, corrosion inhibitor, demulcent, plasticizer, sequestrant, mineral deposition inhibitor, ionic liquid, stabilizer, lubricant, bitumen additive, deinking additive, oil gellant, ore flotation collector, processing aid in the manufacture of plastics, antistatic agent, fertilizer coating additive, for plant protection, for treating textiles and for enhanced oil recovery, for the production of electrodes and electrolytes for batteries,
- wherein:
- R1 and R2, which may be identical or different, represent, independently of each other, a linear, branched or cyclic, saturated or unsaturated hydrocarbon-based group, comprising from 1 to 6 carbon atoms, where the sum of the carbon atoms of the groups R1 and R2 ranges from 2 to 7, R1 and R2 possibly forming, together with the carbon atom that bears them, a 6-, 7- or 8-membered ring;
- 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.
A composition comprising at least one compound of formula (I) and/or a salt thereof, alone or as a mixture, with one or more aqueous, organic or aqueous-organic solvents, and optionally one or more additives and fillers,
- wherein:
- R1 and R2, which may be identical or different, represent, independently of each other, a linear, branched or cyclic, saturated or unsaturated hydrocarbon-based group, comprising from 1 to 6 carbon atoms, where the sum of the carbon atoms of the groups R1 and R2 ranges from 2 to 7, R1 and R2 possibly forming, together with the carbon atom that bears them, a 6-, 7- or 8-membered ring;
- 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.
