  • Patent number: 8575285
    Abstract: Provided is a catalyst used for a living radical polymerization method, which contains a central element consisting of carbon and at least one halogen atom binding to the central element. Further, a hydrocarbon compound can be used as a catalyst precursor. A monomer having a radical-reactive unsaturated bond is subjected to a radical polymerization reaction in the presence of the catalyst, consequently a polymer having narrow molecular weight distribution can be obtained, and thus the cost of the living radical polymerization can be remarkably reduced. The present invention is significantly more environmentally friendly and economically excellent than conventional living radical polymerization methods, due to advantages such as low toxicity of the catalyst, low amount of the catalyst used, high solubility of the catalyst, mild reaction conditions, and no coloration/no odor (no need of any post-treatments for a molded article), and the like.

  • 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.
