    摘要： The present invention relates to a reaction mixture in emulsion form, suitable for conversion into polyurethanes, comprising a first phase and a second phase in the emulsion and further comprising the following components: A) polyols; B) blowing agent; C) surfactants; and D) isocyanates, wherein the isocyanate-reactive compounds A) are present in the first phase of the emulsion and the blowing agent B) is present in the second phase. The blowing agent B) is present in the near-critical or supercritical state and the isocyanate D) is present in the second phase in a proportion of ≧10% by weight of the total amount of isocyanate D) in the composition. The invention further relates to a method of producing polyurethane foams by providing such a reaction mixture, wherein a polymerization takes place at the freshly formed interface between the polyol phase and the blowing agent phase, to the use of such a reaction mixture for producing polyurethane foams and also to the polyurethane foams obtained.

    摘要： A process for isolating rhamnolipids is provided. The process includes providing an aqueous medium containing at least one rhamnolipid and having a pH of less than 6. Next, the aqueous medium is brought into contact with at least one organic solvent to provide a multiphase system and then the aqueous phase is separated off. The pH is then increased to a value of 6 or more to provide a multiphase organic system. Next, a rhamnolipid-enriched organic phase is separated off. An optional step of further purifying the rhamnolipid may be performed.
