    Abstract: Organosilicon compounds bearing silicon-bonded organyloxy groups are prepared by mixing and reacting silanol-functional organosilicon compounds with organosilicon compounds containing at least two organyloxy groups in a mixer with an energy input of at least 0.2 kW/Kg of mixture. At this level of energy input, reaction to form the organyloxy-functional product is rapid, and can be achieved without supplying external heat, and also without catalysts, if desired.

The hydrophobic moiety is sufficiently hydrophobic for the compositions to exhibit reversed phase characteristics and typically incorporates at least 5 carbon atoms in sequence. Based on having both hydrophilic and hydrophobic functionalities, the new stationary phases exhibit unique chromatographic properties. For example, these media can be used in either hydrophilic (HILIC) mode, in which the mobile phase includes a high percentage of an organic solvent, or in reversed phase mode, in which the mobile phase contains a higher percentage of an aqueous solvent.

  • Patent number: 6489498
    Abstract: Silanes of the general formula are prepared, wherein R1, R2 and R3 in the molecule are the same or different and represent aliphatic or aromatic hydrocarbon groups, R4 is a divalent hydrocarbon group with 4 to 12 carbon atoms and a lateral hydroxyl group, wherein the hydrocarbon group can be interrupted by an ether oxygen, R5 is a hydrophilic, ionic group. A method for synthesizing these compounds is described. The silanes greatly lower the surface tension of aqueous solutions, the surface tension being reduced to values of about 23 mN/m. The silanes are biologically degradable and have pronounced surfactant properties.
