摘要： Processes for producing aromatic dicarboxylic acids are disclosed, the processes including a step of combining in a reaction medium a dialkyl aromatic, a solvent comprising water and a saturated organic acid having from 2-4 carbon atoms, and an oxygen-containing gas, at a temperature from about 125° C. to about 155° C., in the presence of a catalyst composition comprising cobalt, manganese, zirconium, and bromine, wherein the weight ratio of cobalt to manganese in the reaction mixture is from about 10 to about 400. The processes provide improved conversion, while reducing the formation of carbon oxides and other by-products.

摘要： Processes for the liquid phase oxidation of one or more of a para- or a meta-substituted dialkyl aromatic compound are disclosed, the processes including a step of combining in a reaction medium the one or more para- or meta-substituted dialkyl aromatic compound, a solvent mixture comprising water and a saturated organic acid having from 2-4 carbon atoms, and an oxygen-containing gas, at a temperature from about 130° C. to about 180° C., in the presence of a catalyst composition comprising cobalt, manganese, bismuth, and bromine. The processes produce the corresponding aromatic dicarboxylic acid product with improved conversion, while reducing the formation of carbon oxides.

摘要： Processes for producing terephthalic acid are disclosed, the processes comprising combining in a reaction medium p-xylene, a solvent comprising water and one or more saturated organic acids having from 2-4 carbon atoms, and an oxygen-containing gas, at a temperature from about 135° C. to about 165° C., in the presence of a catalyst composition comprising cobalt atoms and manganese atoms, with bromine atoms provided as a promoter. The amount of cobalt used may be from about 1,800 ppm to about 6,000 ppm, with respect to the total weight of the liquid in the reaction medium, and the weight ratio of cobalt to manganese may be from about 40 to about 400. The processes according to the invention produce terephthalic acid as a precipitated reaction product, with typically no more than about 10 ppm 2,6-dicarboxyfluorenone produced, with respect to the weight of the terephthalic acid produced, or no more than about 20 ppm 2,6-dicarboxyfluorenone, with respect to the total weight of the reaction medium, per batch or upon one pass through a reactor. The terephthalic acid so produced may be further purified by one or more additional oxidation reactions, without the need for expensive hydrogenation purification processes.

摘要： Resol beads are disclosed, having a relatively narrow size distribution, prepared in high yield by reaction of a phenol with an aldehyde, with a base as catalyst, in the presence of previously-formed resol beads, a colloidal stabilizer, and optionally a surfactant. The resol beads may be thermally treated to prevent sticking and clumping and have a variety of uses, such as in the formation of activated carbon beads.
