Abstract: New highly-effective non-halogen, low VOC, low fogging, and cost-effective oligomeric polyphosphonate flame retardants for flexible polyurethane foams as well as for other flame retardant applications are described. In addition, methods for the preparation and uses of such new highly effective flame retardants are described.
Abstract: Quite unexpectedly, by suitably modifying the crystal structure of hydrogarnets of the general formula MII3MrI-III2(OH)12 (where MII denotes divalent metal ions, especially alkaline earth metal ions, of Group IIA of the periodic table and MIII denotes trivalent metal ions of Group IIIA of the periodic table, especially aluminum) with suitable amounts of incorporated silicate and/or phosphate, flame retardants having both a higher flame retardant efficiency than such traditional mineral flame retardants as ATH and MDH, and a higher thermal stability than ATH can be produced. It has also been found that synthetic hydrogarnets of the general formula MII3MrIII2(OH)12(where MII and MIII are as defined above) having cubic crystal and these synthetic hydrogarnets also show high flame retardant efficiency.

Abstract: Methods of processing four-legged slaughter animals for consumption as meat and/or meat product(s) are described. The methods comprise I) contacting exterior surfaces of the live animal at least once with a microbiocidal solution formed from mixing together at least (i) water and (ii) at least one N,N?-bromochloro-5,5-dialkylhydantoin, such contacting occurring at least once when the animal is en route to being slaughtered but before it is killed by exsanguination; or II) contacting the carcass of the animal, after exsanguination, with a microbiocidal solution formed from mixing together at least (i) water and (ii) at least one N,N?-bromochloro-5,5-dialkylhydantoin or III) contacting at least one raw meat product and/or at least one processed meat product derived from the carcass. The contacting can be done one or more times in each of I), II), and III). Considerable advantages, which are described, are realized when using such methods.
Abstract: Mercury adsorbed from combustion gas by activated carbon can be sequestered in concrete containing air-entraining admixtures. The activated carbon may be made by providing a carbon char made from coconut shell, wood, or lignite that was activated by a method selected from the group consisting of activating with steam, activating with CO2, activating in an environment containing free oxygen, and combinations thereof to provide an activated carbon with an Acid Blue 80 Index of less than about 30 milligrams per gram of carbon. The activated carbon may be injected into a combustion gas stream containing fly ash and mercury and may then be removed with fly ash from the gas stream. The resulting composition may be used as a partial substitute for cement in air-entrained concretes.

Abstract: Novel methods for producing 1,2,4-triazol-3-one from semicarbazide hydrochloride and formic acid are provided. In methods of this invention, water is used in removal of unreacted formic acid to increase yield and purity of produced 1,2,4-triazol-3-one.
Abstract: This invention provides a process for the N-halogenation of at least one 5-hydrocarbyl hydantoin and/or at least one 5,5-dihydrocarbyl hydantoin. The process comprises concurrently feeding into a reaction zone (i) water, inorganic base, and 5,5-dimethylhydantoin, these being fed separately and/or in any combination(s), (ii) a separate feed of a brominating agent, and (iii) a separate feed of a chlorinating agent, in proportions such that during all or substantially all of the time the concurrent feeding is occurring halogenation of the 5-hydrocarbyl hydantoin and/or 5,5-dihydrocarbyl hydantoin occurs and resultant halogenated product precipitates in the liquid phase of an aqueous reaction mixture, and in which the pH of the liquid phase is continuously or substantially continuously maintained in the range of about 2.0 to about 8.0 during all or substantially all of the time the concurrent feeding is occurring.

Abstract: Granules of racemic sodium ibuprofen dihydrate formed from components specified herein have very desirable properties and can be effectively used in conventional rotary press tableting equipment without operational difficulties often encountered in actual practice. Their preparation by a wet granulation process, the wet granule compositions, formulations adapted for preparation of solid dosage forms utilizing a rotary press, solid dosage forms, and methods of preparing solid dosage forms in a rotary press are also described.
Abstract: Microbiological control is achieved by continuously and inexpensively dosing water in contact with biofilm, or that comes into contact with biofilm, using a highly effective biocide that provides very effective microbiocidal control of planktonic microorganisms and of biofilm species, even where the biofilm infestations have been in existence for long periods of time and thus have encased themselves in a substantial quantity of slimy defensive polysaccharide layers or films. In addition, the biocide used makes possible significant reduction in copper and/or iron surfaces in contact with the water as compared to N,N?-bromochloro-5,5-dimethyl hydantoin. Still other advantages are made possible by the described technology.

Abstract: This invention relates flame retardant compositions containing low molecular weight brominated anionic, chain transfer, vinyl aromatic polymers, hereinafter “ACTVAP”. The compositions can accommodate high bromine content while still exhibiting a low thermally labile bromine content. The compositions have glass transition temperatures, Tg, that are predictive of acceptable melt flows and heat distortion temperatures (HDT) in HIPS and ABS based formulations substrates. The compositions, are suitable flame retardant candidates for use in thermoplastic formulations, e.g. polystyrene and ABS formulations.
