Abstract: In a water-continuous system and a polymerization method, the water-continuous system comprises a polymerizable aromatic compound as an oil, water and a non-ionic surfactant, wherein the polymerizable aromatic compound is a component from the group consisting of: thiophene, furan and alkyl, alkoxy or alkylenedioxy derivatives of thiophene and furan. The non-ionic surfactant is an alkyl polyethoxylate and/or an alkyl polyglucoside.

Abstract: In a method for in situ cleanup of soil contaminated with a pollutant, a micro-emulsion containing an oil component with triglycerides, or essential oils or fatty acid esters or mixtures thereof, and a surfactant component of one or more branched or multi-chain anionic surfactants is used for pollutant extraction. The extraction of pollutant from the contaminated soil is carried out at a temperature range of 0° C. and 200 ° C. The oil component of the micro-emulsion contains one or more triglycerides or fatty acid esters in amounts ≧5% by weight and less than 50% by weight, one or more dialkyl sulfosuccinic acid compounds as an anionic surfactant, and one or more branched, multi-chain or multi-chain branched non-ionic surfactants. The anionic and non-ionic surfactants are present in the micro-emulsion in an amount of ≦30% by weight.

Abstract: In a process for the extraction of organic compounds contained in an aqueous solution of non-ionic surfactants which contain the organic compounds to be extracted, the aqueous solution is intensely mixed with a liquid which is not miscible with water whereby the organic compounds transfer to the liquid which is not miscible with water, and the blend of the aqueous solution and the liquid which is not miscible with water is then separated, the mixing and the separation process being performed in a centrifugal extractor.

Abstract: A process for decontaminating a solid material contaminated with an organic pollutant wherein the solid material contains grains with a particle size of up to 60 microns, which includes the steps of:(a) extracting the organic pollutant from the solid material containing grains with the particle size up to 60 microns by using a microemulsion which includes a thermodynamically stable, macroscopically homogeneous and optically transparent mixture of water, an apolar hydrophobic solvent, and a surfactant to form a cleaned solid material and a pollutant-containing microemulsion;(b) separating the cleaned solid material from the pollutant-containing microemulsion; and(c) splitting the pollutant-containing microemulsion into a surfactant-rich phase and a pollutant-containing phase.
