  • Patent number: 10815421
    Abstract: The present invention discloses liquid quaternary ammonium salts that can be used to treat and coat the surfaces of the proppant sand or inorganic particles that are used in down-hole oil well fracturing operations as well as the containment structure and that these treated surfaces will cause water and oils to flow faster through the porous structure. These liquid quaternary ammonium salts can be chosen from a list that includes but is not limited to cocobis(2-hydroxyethyl)ethylammonium ethyl sulfate, benzylcocobis(hydroxyethyl)ammonium 2-ethylhexylsulfate, dibenzylcocobishydroxyethyl ammonium phenolsulfonate, didecyldimethyl-ammonium dodecylbenzenesulfonate and tallow-bis(2-hydroxyethyl)ethylammonium ethyl sulfate.

  • Publication number: 20060000025
    Abstract: The invention provides a method for preparing insecticidally treated textile having improved properties. A novel combination of an insecticide and certain polymeric binder(s) or dye fixatives is used to coat and/or impregnate fabric via a combination of application methods used in the textile industry. The insecticide-binder or insecticide-dye fixative combination and the method by which it is applied to the textile yield a coated fabric and, ultimately, finished goods with improved wash durability of the insecticide over several launderings and prolonged insecticidal efficacy.

  • Publication number: 20050235877
    Abstract: The present invention provides a dispersant for aqueous and non-aqueous systems which can disperse insoluble fine powders in non-aqueous liquids in a short period of time and give long-term dispersion stability to the resulting dispersions without allowing the formation of hard cake or precipitates. The dispersant is a compound of the formula wherein SO is styrene oxide; R is a C8-C22 saturated or unsaturated group; x=0-100; y=1-3; z=0-100 and s=0-100. The dispersant of the invention is also particularly effective for dispersing additives into polymers such as polyesters, polyamides, polycarbonates, polyethylene and polypropylene.
