Provided is a compound which may be obtained by esterification condensation of components as described herein. The compound may be used as a collector for ore enrichment (flotation), as a corrosion inhibitor, as a viscosity enhancer, emulsifier or stabilizer that is useful for the oil and gas industry, as a clay modifier, as an adhesion promoter, as an antiagglomerant additive, as an additive in haircare products, as a fabric softener, as an antistatic agent in polymers, as a bitumen emulsion additive, as a detergency cationic agent, as a fertilizer additive, as an antiagglomerant for hydrates, as a lubrication or adhesion-promoting additive, for example.

Polyesteramines and polyesterquats

The present invention relates to the use for ore beneficiation, of at least one derivative of alkoxylated (polyester)amine. The present invention also relates to the flotation pulp and the tailings comprising said product useful for ore beneficiation.

Use of alkoxylated amines as collector agents for ore beneficiation

Provided is a method of beneficiating an ore including contacting an ore with a compound represented by formula (1): where the structural variables are defined herein.

The present invention relates to a method for preparing 1-(2-aminoethyl)imidazolidin-2-one or the thiocarbonyl thereof, and also to the product that can be obtained according to this method, and which has a purity of at least 98%, and to the uses thereof.

Method for preparing and using aminoethyl imidazolidinone and the thiocarbonyl thereof

Method for preparing aminoethyl imidazolidinone or the thiocarbonyl thereof

This invention relates to latex dispersions that are based on (co)polymers with one or more n-alkyl(meth)acrylate monomers with n a varying from 6 to 40, and optionally one or more monomers that are not very water-soluble of the (meth)acrylic and/or vinyl type, optionally one or more polar monomers that are selected from among the (meth)acrylamides and their derivatives and optionally one or more monomers that are selected from among the ethylenically unsaturated monocarboxylic and/or dicarboxylic acids or anhydrides. These dispersions are obtained by radical-type emulsion polymerization in the presence of water. They can be used as is for the inhibition of the deposition of paraffins that are contained in the crude petroleum hydrocarbons or else diluted in one or more solvents.
