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

Provided is an aqueous acidic emulsifying composition comprising a specific amine and a polymerized fatty acid, a process for preparing the composition, a process for preparing bituminous emulsion and to the use of the composition for spreading bitumen.

Emulsifying composition for spreading bitumen

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 composition including at least one bitumen and at least one additive as defined herein. The composition provides emulsions of all types of bitumens, which can be used in the production of cold-poured mixes, having an improved internal strength and a rapid increase in cohesion.

Composition comprising one or more particular additives

The present invention relates to a compound of formula (I): 

Ether amine compounds and use thereof as flotation collector

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 bitumen additive mixtures, their use and application for the fabrication of asphalt mixtures used in pavement and waterproofing, and more specifically for construction, repair and maintenance of sidewalks, roads, highways, parking lots or airport runaways and service roads and any other rolling surfaces.

Additive mix for asphalt mixture preparation

The invention concerns a semi-continuous method for preparing an emulsion of droplets of a phase A in a phase B, including the following steps: (i) mixing an amount of phase A and an amount of phase B using a multi-shaft mixing system comprising at least one scraping agitator, so as to obtain a dispersion of phase A in phase B with a volume concentration of phase A higher than 74%; (ii) diluting the dispersion obtained in step (i) by adding an additional amount of phase B, and mixing using said multi-shaft mixing system, so as to obtain an emulsion of droplets of a phase A in a phase B.

Method for preparing a calibrated emulsion

The present invention relates to bitumen emulsions that can be used in roadmaking applications for the production of cold mixes, emulsion-stabilized gravel and road pavements obtained at ambient temperature, the cohesion of which at young age is substantially improved over the cold mixes, emulsion-stabilized gravel and road pavements of the prior art. These bituminous emulsions are characterized by a median diameter of 0.6 &#x3bc;m or less, and preferably 0.5 &#x3bc;m or less.

Bituminous emulsions, their method of preparation and their use for the production of materials and road pavements

The invention relates to a process for preparing 1,1,1-trifluoro-2,2-dichloroethane (F123). This process consists in placing 1,1,1-trifluoro-2-chloroethane (F133) in contact with chlorine in the presence of hydrogen fluoride and a fluorination catalyst. F133may be obtained by fluorination of trichloroethylene, and the F123 may be subsequently fluorinated to F125.

Process for the preparation of 1,1,1-trifluoro-2,2-dichloroethane

Mixed fluorination catalyst comprising one or more nickel and chromium oxides, halides and/or oxyhalides deposited on a support composed of aluminium fluoride or of a mixture of aluminium fluoride and alumina, characterized in that the weight of nickel/weight of chromium ratio is between 0.08 and 0.25, preferably between 0.1 and 0.2.

Mixed fluorination catalyst

The present invention relates to a catalyst based on titanosilicalites having a content by weight of alkali metal or metals of between 0.05 and 2%. The subject of the invention is more particularly a process for producing N,N-disubstituted hydroxylamine from hydrogen peroxide and the corresponding disubstituted amine.
