  • Publication number: 20110124745
    Abstract: Reversibly switchable negatively charged surfactants are provided. The anionic surfactant is formed in aqueous solution by providing an absence of CO2 and is converted to a non-surfactant neutral state through exposure to CO2. The anionic switchable surfactants are useful to stabilize emulsions. In the neutral state they are useful to separate immiscible liquids. The surfactants find uses in polymerization, the oil industry, remediation of oil-contaminated soil and recapture of oil contaminant, and formation of solid particles such as plastics and nanoparticles.

  • Patent number: 6586609
    Abstract: Process for the esterification of organic acids with alcohols in a reactor of the chromatographic type in which the heterogeneous solid phase is capable of acting both as an esterification catalyst and as a means exhibiting preferential adsorption towards one of the reaction products (typically water). The process to which the present invention relates is particularly improved compared with conventional technology owing to the use, as the means for regenerating the catalyst, of a desorbent to which has been added a second compound, generally the anhydride of the acid used in the esterification reaction, which, by chemical reaction, completes the removal of the adsorbed water.

  • Patent number: 6509507
    Abstract: A process for preparing polymerizable biaryl derivatives comprises reacting an aromatic comprising a 6-membered ring which bears ester or benzylic OH groups in the 1,4 position with a second aromatic in a palladium-catalyzed cross-coupling reaction to give a biaryl and converting the ester or benzylic OH groups into polymerizable groups in one or more steps. The biaryls obtained are suitable for preparing polymers which are used as electroluminescence materials.
