  • Patent number: 6090965
    Abstract: Dissolved silanes, silicones and silicates from solvents used in the slurry phase Direct Synthesis of alkoxysilanes are removed by adding a carboxylic acid such as formic acid to generate filterable precipitates and reusable solvent. The solvents are thereby remediated and made suitable for reuse in Direct Synthesis processes. Foaming is reduced with the remediated solvent and silicon conversion rates are higher. The precipitates are easily filtered and retain negligible quantities of solvent.

  • Patent number: 5877268
    Abstract: The invention discloses a new class of silicone surfactants and their use for the preparation of flexible urethane foam. The surfactants incorporate high molecular weight polyethers prepared with narrower molecular weight distributions than conventional polyethers. These polyethers are prepared using a double metal cyanide (DMC) catalyst. These surfactants are better foam stabilizers than the analogous surfactants prepared from conventional polyethers.

  • Patent number: 5869727
    Abstract: Disclosed is an improved process for the manufacture of silicone containing copolymers via a hydrosilation reaction, in which the catalyzed reaction of organohydrosiloxane and olefinic polyether is carried out at between 20.degree.-120.degree. C., preferably 70.degree.-120.degree. C., under a vacuum between 750-1 mmHg. The reaction under these conditions results in a copolymer of a higher quality as compared to copolymers made by the traditional method without the benefit of a vacuum. If desired, the reaction can be taken to its clear point in a volatile compatibilizing solvent (for example toluene, xylene, or isopropyl alcohol), this solvent can then be removed from the reaction system, and another less volatile solvent, such as dipropylene glycol or polypropylene glycol, may then be added.
