    Abstract: A method for preparing tetrabromobenzoate ester from a tetrabromophthalic anhydride including the steps of reacting the tetrabromophthalic anhydride with a catalyst and an alcohol at a temperature that favors partial esterification over complete esterification of the tetrabromophthalic anhydride to form a tetrabromophthalate half-ester reaction mixture; and feeding the half-ester reaction mixture to at least one reactor having and maintaining a temperature that favors decarboxylation over esterification to produce a tetrabromobenzoate ester-containing product. The temperature favoring partial esterification of the tetrabromophthalic anhydride is between about 70° C. and 130° C. The temperature favoring decarboxylation over esterification is between about 190° C. and 205° C. The tetrabromobenzoate ester-containing product comprises at least about 85% tetrabromobenzoate ester. The at least one reactor may include two or more reactors connected to one another in series.

  • Patent number: 7307188
    Abstract: A method and apparatus for purifying carboxylic acids is disclosed. A mixture containing crude carboxylic acid is contacted with a selective crystallization solvent to form a slurry of a salt complex of the carboxylic acid and the selective crystallization solvent. The salt complex is recovered and optionally processed to recover the free carboxylic acid. The method and apparatus of the invention is particularly suitable for purifying aromatic dicarboxylic acids such as terephthalic acid. The present invention also reduces contamination by carboxybenaldehyde isomers in crude phthalic acids by oxidizing the carboxybenzaldehyde to the corresponding phthalic acid.

  • Patent number: 7307191
    Abstract: This present invention provides materials for use as solid or concentrated chemical precursors for the production of organic peroxy acids (peracids). Organic peroxy acids are formed using a precursor according to the invention when they are combined with hydrogen peroxide or a hydrogen peroxide precursor such as a percarbonate or a perborate in aqueous medium. Organic peroxy acids, such as peroxyacetic acid, are used currently to disinfect medical equipment such as endoscopes and related items.
