摘要： The present invention is related with the obtaining process and use of branched germinal zwitterionic liquids based on either bis-N,N-dialkyl-N-polyether-betaine or bis-N, N-dialkenyl-N-polyether-betaine or bis-N, N-dicycloalkyl-N-polyether-betaine or bis-N,N-diaryl-N-polyether-betaine, to be applied as modifiers of the wettability of rocks such as limestone, dolomite, sandstone, quartz or heterogeneous lithologies, under the presence of brines having high content of divalent ions such as calcium, magnesium, barium or strontium, under high temperature and high pressure within enhanced oil recovery processes in order to increase the oil production.The branched germinal zwitterionic liquids of the present invention have moreover the property to act as viscosity reducers of heavy oils having high content of polar fractions, both for extraction and production, and transport and storage operations, so allowing increase the production level of this oil type. An additional advantage shown by the zwitterionic liquids, derived from their molecular structure, is that they can be handed in such a manner that can be dissolved by water, hydrocarbon or other polar and non-polar solvents.

摘要： The present invention is related to a process for obtaining organic ammonium salts (OAS) and their derivatives, supramolecular surfactants (SS), which simultaneously present the properties of traceability and detergents dispersant of organic scales. Organic ammonium salts (OAS) and their derivatives supramolecular surfactants (SS) have applications as differentiators, markers, or tracers in fuels derived from hydrocarbons; and also to disperse organic scales or inhibit the gums precipitation both in injectors and intake valves of automotive vehicle engines. Organic ammonium salts (OAS) are obtained through an acid-base reaction between a molecule from the azo family and an amine. Once the OAS is obtained, it reacts with an organic compound (OC) so that through non-covalent interactions, a self-assembly process occurs that gives rise to the SS. Said process is based on green chemistry, that is, in the absence of solvents. These OAS and SS are quantified through the analytical techniques of ultraviolet-visible (UV-VIS) and high-performance liquid chromatography (HPLC) through a calibration curve. Additionally, its performance as a gum-dispersing agent in a single-cylinder engine is evaluated.

摘要： The present disclosure is related to obtaining and using sulfobetaine and hydroxysultaine-based geminal zwitterionic liquids as wettability modifiers for rocks such as limestone, dolomite, sandstone, quartz or heterogeneous lithologies, under the presence of brines having high content of divalent ions as calcium, magnesium, barium and strontium, at high temperature and high pressure conditions for enhanced oil recovery processes to increase the oil production. The geminal zwitterionic liquids of the present disclosure have also the property of acting as corrosion inhibitors of ferrous metals used in pipelines and equipment for crude oil extraction, production, transport and storage operations. A further advantage shown by zwitterionic liquids derived from their molecular structure is they can be dissolved in distilled water, brine, hydrocarbon solvents, aromatics and alcohols.

摘要： The present invention relates to supramolecular surfactants (SS) with detergent-dispersant of heavy organic compounds (deposits and/or organic scales) and corrosion inhibition properties, and methods for preparing these surfactants. The invention also relates to the corresponding uses and applications of these surfactants to prevent and control the formation of deposits in internal combustion machines, as well as to prevent and protect pipelines, tanks, motors and complements of ferrous materials against corrosion where there is contact with liquid hydrocarbons such as gasoline, turbosine, and diesel, where gasoline may contain oxygenated compounds such as ethers and/or alcohols. The supramolecular surfactants are obtained from the self-assembly process between oxazolidines derived from polyalkyl/polyalkenyl N-hydroxyalkyl succinimides with alkyl/alkenyl-amine-propanoic acids and alkyl/alkenyl-amine-di-propanoic acids. The concentration of supramolecular surfactants in liquid fuels is quantified through a process based on determining the interfacial tension in a fuel/water/supramolecular surfactant system.
