  • Patent number: 10925302
    Abstract: The viscosity of aqueous dispersions of normally solid organic peroxides may be advantageously lowered through the use of surfactants which are polyglyceryl esters of C6-C12 fatty acids. The reduction in viscosity facilitates milling the peroxides to reduce particle size and also provides dispersions of small particle size peroxides which may be readily poured or pumped. The aqueous dispersions are useful as components of pharmaceutical, personal care, and cleaning products and the like and are effective decolorizing agents for food products, industrial products and the like.
    Type: Grant
    Filed: November 29, 2017
    Date of Patent: February 23, 2021

  • Patent number: 9937473
    Abstract: Provided are dispersions which comprise more than about up to 55 percent by weight or more of an organic peroxide which is normally solid in an anhydrous liquid phase such as dibutyl maleate or dioctyl adipate, with about 5% by weight or more fumed silica to provide a thixotropic, storage stable organic peroxide paste. Addition of about 5 weight % or more of fumed silica was found to result in the formation of a shear thinning anhydrous dispersion of organic peroxide which was storage stable.

  • Publication number: 20110086959
    Abstract: Provided are dispersions which comprise more than about (40) percent by weight of an organic peroxide which is normally solid, an effective dispersing amount of a pharmaceutically acceptable dispersing agent and water. The water and about (40) percent or more peroxide forms a paste. Addition of the dispersing agent/surfactant to a non-flowing organic paste resulted in the formation of a shear thinning aqueous dispersion. The aqueous dispersions can also contain optional components such as thickening agents and anionic emulsifiers.

  • Patent number: 4846584
    Abstract: A fast reacting, automated calorimeter includes a reaction vessel containing a chemically reacting mass, a fluid circulation system containing heat transfer fluid, a portion of the system passing the fluid through the reaction vessel for exchanging heat between the fluid and the reacting mass, a flow rate controller at least generally responsive to variations in temperature of the reacting mass to vary the flow rate of the fluid circulated through the reaction vessel portion of the circulation system, a flow rate signal generator generating a signal related to the varying flow rate of the fluid passing through the reaction vessel portion of the fluid circulation, and a circuit, preferably including a computer, responsive at least to the flow rate signal and generating a heat flow signal generally related to instantaneous rate of heat exchange between the reacting mass and the fluid.
