  • Publication number: 20080237555
    Abstract: 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.

  • Patent number: 6380440
    Abstract: Process for the preparation of 3-bromoanisole comprising methoxydenitrating 3-bromonitrobenzene in the presence of a phase-transfer catalyst (PTC), and the preparation of 3-bromonirtobenzene by the bromination of nitrobenzene with bromine in oleum. The methoxydenitration reagent in an alkali metal methoxide, which is selected from sodium methoxide and potassium methoxide. The amount of methoxide used is 1-1.5 mol per mol of 3-bromonitrobenzene. The alkali methoxide can be a pre-prepared solid or it can be prepared in situ, by the reaction of the corresponding alkali hydroxide and methanol. In the case when pre-prepared solid methoxide is used, the effective amount of alkali hydroxide is between 1.2-1.7 mol per mol of 3-bromonitrobenzebe. The reaction temperatures are between about 40 to 80° C., with preference to reaction temperatures of 50 to 55° C. In the case in which methoxide is prepared in situ, the effective amount of alkali hydroxide is between 2.2-2.4 mol per mol of 3-bromonitrobenzene.
