A method produces porous materials by expansion of polymer gels. The porous materials can be a micro- or nano-porous polymer materials.

Production of porous materials by the expansion of polymer gels

The invention relates to an aqueous washing liquor in a device for cleaning soiled textile substrates, containing a plurality of water-insoluble solid particles and a liquid phase which contains a microemulsion, and to a textile washing method using said type of washing liquor.

Washing liquor comprising a Winsor II microemulsion and insoluble particles, and washing method

A method for producing porous materials is disclosed. The porous materials can be produced by expansion of polymer gels.

A polyurethane foam, polyisocyanurate foam or polyurea foam is obtainable from the reaction of a mixture comprising A) a compound reactive towards isocyanate ('NCO-reactive compound'); B) a blowing agent selected from the group comprising linear, branched or cyclic C1 to C6 hydrocarbons, linear,branched or cyclic C1 to C6 fluorocarbons, N, O, argon and/or CO, where the blowing agent B) is present in the supercritical or near-critical state; C) a polyisocyanate; D) an amphiphilic isocyanate; and E) optionally a surfactant and F) optionally other auxiliaries and additives. The invention further relates to the production of this polyurethane foam, where the blowing agent is emulsified in the isocyanate component containing amphiphilic isocyanate.

Polyurethane foam and process for producing same

The invention relates to a process for generating a porous material having homogeneous, gas-containing inclusions in the micrometer and sub-micrometer range, and also to the material produced by such process.

Generation of nanodisperse inclusions in a high-viscosity matrix

The present invention relates to a process for producing a foamed material, wherein a composition in the form of emulsion with a matrix-forming component, a surfactant component and a near-critical or supercritical blowing agent component is submitted to a lowering of pressure. The blowing agent component further comprises a hydrophobic co-component, which is soluble in supercritical COat a pressure of &#x2267;150 bar, is insoluble in subcritical COat a pressure of &#x2266;40 bar and is insoluble in the matrix-forming component and furthermore is present in a proportion from &#x2267;3 wt % to &#x2266;35 wt % of the blowing agent component. It further relates to a composition in the form of emulsion to be used herein and a foamed material obtainable by the process according to the invention.

Process for producing a foamed material,composition in the form of emulsion used therein and foamed material obtainable therefrom

The present invention relates to a process for producing a polyurethane foam, where the blowing agent used is present in the supercritical or near-critical state. A reaction mixture is introduced into a closed mould, where the closed mould has been set up in such a way that its interior volume and/or the pressure prevailing in its interior can be altered after the introduction of the mixture by external influence. Through the selection of the surfactant it is possible to obtain microemulsions of the blowing agent in the polyol phase. The invention further relates to a nanocellular polyurethane foam obtainable by the process of the invention.

Process for producing a polyurethane foam and polyurethane foam obtainable therefrom

A process for operating an internal combustion engine or a nozzle includes producing a fuel mixture in-situ. The fuel mixture consists of a polar component A, a nonpolar fuel component B, an amphiphilic component C, and an auxiliary component D. The fuel mixture is produced in a high-pressure region of an injection system of an internal combustion engine or of a nozzle within 10 seconds of an injection operation. The fuel mixture is injected into the internal combustion engine or the nozzle. A pressure is in a range of from 100 to 4,000 bar.

Method for the in situ production of fuel/water mixtures in combustion engines

The invention relates to bicontinuous microemulsions and to the use thereof as a fuel, combustion or heating fluid. Said fuels permit an increased efficiency of internal combustion systems and heating installations of any type and, simultaneously, a minimized emission of pollutants, associated with combustion, to be obtained.

Microemulsions and use thereof as a fuel

The present invention describes organic electronic devices in which at least one organic layer of low refractive index is introduced. The light output of the electronic devices is thereby improved.
