  • Patent number: 8268269
    Abstract: As population density increases, the transportation of hazardous chemicals, including acids and disinfectants, lead to an increased incidence of spills while the consequences of spills become more serious. While solutions of halide acids, hypohalites and halites are safer disinfectants for transportation, handling, storage and use than traditional gaseous chlorine, the manufacturing cost of these disinfectants has here-to-fore limited their use. Economical processes are presented for the manufacture of O2, halogen oxides, halide acids, hypohalites, and halates; as well as polynucleate metal compounds, metal hydroxides and calcium sulfate hydrate (gypsum). The instant invention presents methods and processes that incorporate the use of sulfur. This is while environmental regulators, such as the US EPA, require an increased removal of sulfur from hydrocarbon fuels, thereby creating an abundance of sulfur, such that the refining industry is in need of a way to dispose of said abundance of sulfur.

    Abstract: Disclosed is a clean method for preparing layered double hydroxides (LDHs), in which hydroxides of different metals are used as starting materials for production of LDHs by atom-economical reactions. The atom efficiency of the reaction is 100% in each case because all the atoms of the reactants are converted into the target product since only M2+(OH)2, M3+(OH)3, and CO2 or HnAn? are used, without any NaOH or other materials. Since there is no by-product, filtration or washing process is unnecessary. The consequent reduction in water consumption is also beneficial to the environment.

  • Publication number: 20100092441
    Abstract: Inorganic anions nitrate and nitrite influence metabolic rate and glucose homeostasis. Infusion of nitrite iv caused an acute drop in resting energy expenditure (oxygen consumption) and nitrate, when given perorally, caused a drop in oxygen consumption during exercise and a depression of the increase in blood glucose observed after an oral glucose tolerance test. The doses of nitrate and nitrite did not cause any detectable change in methemoglobin levels of blood. Also, nitrate and nitrite did not alter lactate levels in blood. This discovery provides useful treatments to regulate the energy expenditure and glucose homeostasis of a mammal by administration of inorganic nitrite and/or nitrate.

    Abstract: A gas generant composition used in pressure activated restraint system devices such as micro-gas generator applications such as seat belt pretensioners is provided. The gas generant composition includes a potassium perchlorate gas generant additive in addition to a non-azide nitrogen-containing gas generating fuel, a metal ammine nitrate oxidizer, and a metal oxide burn rate enhancing and slag formation additive. The gas generant composition desirably has improved ignitability as compared to a similar composition without the potassium perchlorate gas generant additive. The gas generant composition also desirably produces or results in effluents having either or both reduced carbon monoxide and NOx contents as compared to the effluent produced or resulting from a similar composition but without the inclusion of the potassium perchlorate gas generant additive.

  • Patent number: 7105136
    Abstract: In a method for preparing copper salts from at least one cupriferous and one additional reactant, the reactants are used to prepare micro-emulsions while employing at least one block polymer, the intermediate products obtained this way are mixed and reacted together so as to form a micro-emulsion. The preparation of the starting micro-emulsion as well as the subsequent joint reaction preferably occur either with ultrasound or in a high-pressure homogenizer. The copper salts obtained this way exhibit a particle size of less than 50 nm, preferably 5 to 20 nm and can be adjusted to specific applications through the appropriate doping of foreign ions.
