  • Method of making a halosiloxane
    Patent number: 11584767
    Abstract: A method of producing a halosiloxane, the method comprising: combining water, a halosilane, and a first solvent, where the first solvent has a water solubility of >1.5 grams in 100 ml of solvent, to form a reaction mixture having a temperature above the melting point temperature of the solvent, partially hydrolyzing and condensing the halosilane to form a reaction product mixture comprising the halosiloxane, the solvent, a hydrogen halide and unreacted halosilane, and, optionally, adding a second solvent with a boiling point?the boiling point of the halosiloxane to the reaction mixture or the reaction product mixture.
    Type: Grant
    Filed: May 24, 2018
    Date of Patent: February 21, 2023

  • Polymerized polymeric fluid storage and purification method and system
    Patent number: 7955416
    Abstract: A method of storing and dispensing a fluid includes providing a vessel configured for selective dispensing of the fluid therefrom. A polymerized polymeric material is provided within the vessel. The fluid is contacted with the polymerized polymeric material for take-up of the fluid by the polymerized polymeric material. The fluid is released from the polymerized polymeric material and dispensed from the vessel.

  • Fluid Storage and Purification Method and System
    Publication number: 20080296305
    Abstract: A method and device for storing and dispensing a fluid includes providing a vessel configured for selective dispensing of the fluid therefrom. Provided within a vessel is a nancomposite material comprising an imidazolium surfactant and an integral solvent that is essential to the formation of the nancomposite material. The fluid is contacted with the nanocomposite material for take-up of the fluid by the polymerized nanocomposite material. The fluid is released from the nanocomposite material and dispensed from the vessel.
