| 20080237555 | Scorch prevention in flexible polyurethane foams - Compositions are provided for alleviating or preventing discoloration, known as “scorching”, in flame-retarded flexible polyurethane foams. The anti-scorch compositions contain combinations of antioxidant agents, epoxy compounds, organic phosphites—alone or in combination with metal salts of carboxylic acids. The compositions are useful, for example, for polyurethane foams retarded with aliphatic or aromatic phosphorus-based flame retardants, or with halogen-containing flame retardants. | 10-02-2008 |
| 20080281024 | Flame Retardant Bromobenzyl Systems - Polybrominated bisaryl compounds containing bromomethyl or bromomethylene groups are provided, as well as flameproof polymeric formulations comprising the compounds. The novel compounds exhibit a good thermal stability, and are particularly suitable for flame-retarding polystyrene thermoplastic foams. A process for making the polybrominated bisaryl compounds is also provided. | 11-13-2008 |
| 20100113630 | Flame retardant Composition - A liquid flame retardant composition having one or more flame retarding agents, which are the epoxides obtainable by reacting tetrabromobisphenol A with epichlorohydrin and their end-capped derivatives represented by Formula (1), is provided. The liquid composition is especially useful in the preparation of rigid polyurethane foams. | 05-06-2010 |
| 20100152501 | Process of preparing bromopicrin - Process of preparing high purity bromopicrin, and high purity bromopicrin produced therefrom. Providing a mixture of nitromethane and bromine, and preferably water, and absent of organic solvent. Adding an aqueous solution of an alkaline substance to the mixture, thereby providing a reaction mixture containing bromopicrin, the adding performed such that no excess of the alkaline substance occurs in the reaction mixture during the adding. Collecting the organic phase (containing the bromopicrin) from the reaction mixture. No need for subjecting the organic phase of the reaction mixture to distillation or extraction, for obtaining near quantitative yield of bromopicrin having purity of at least equal to or greater than 96 weight percent. Process parameters controlling selectivity of reaction forming bromopicrin are molar ratio of bromine and nitromethane in the mixture; reaction temperature while bromopicrin is formed; concentration of the alkaline substance in the aqueous solution; and reaction time. | 06-17-2010 |
| 20100204528 | CONTINUOUS PROCESS OF PREPARING BROMOPICRIN - A continuous process of preparing bromopicrin is disclosed. The process is effected by transferring a continuous flow of a first mixture and a continuous flow of a second mixture into a first reactor, the first mixture containing nitromethane and bromine and the second mixture containing an aqueous solution of an alkaline substance, to thereby obtain a reaction mixture which comprises bromopicrin in said first reactor; and collecting the bromopicrin from the reaction mixture. Highly pure bromopicrin obtained by this process is also disclosed. | 08-12-2010 |
| 20100291230 | Novel Pesticide Compositions - Novel pesticide compositions and formulations, containing a phosphorous-containing compound and a nitrogen-releasing compound, are disclosed. These novel compositions exhibit a synergistic pesticidal activity and are particularly useful in treating pests such as nematodes (including root-not nematodes), fungi and bacteria. Methods utilizing these compositions for controlling pests, articles-of-manufacture containing same and processes of preparing same are further disclosed. | 11-18-2010 |
| 20100313792 | Additives For Altering The Hardening Rate Of Chemically Bonded Silico-Phosphate Cements And Method Therefor - A method is provided for advantageously altering the rate of hardening of a magnesium silico-phosphate cement (MSPC). Addition of on the order of 1% of an [MF | 12-16-2010 |
