摘要： Disclosed is a process to produce a purified carboxylic acid slurry. The process comprises removing impurities from a crystallized product in a solid liquid displacement zone to form the purified carboxylic acid slurry. The process produces purified carboxylic acid slurry having good color and low impurity levels without the use of purification steps like hydrogenation or an impurity removal process.

摘要： Disclosed is a process for the preparation of a dimethyl cyclohexanedicarboxylate by the hydrogenation of the corresponding dimethyl benzenedicarboxylate ester in the presence of a class of supported catalysts comprising palladium and a second Group VIII metal selected from nickel, platinum, ruthenium or a mixture thereof deposited on an alumina support which have a unique combination of characteristics. The use of the catalysts permits the process to be carried out at significantly lower process pressures.

摘要： Disclosed is an improved process for the continuous production ofaromatic carboxylic acids such as terephthalic acid by the liquid-phase oxidation of an alkyl aromatic compound using an oxygen-containing gas. Operation of the process is improved by providing a spray of recycled reaction medium at or near the top of a columnar oxidation vessel to minimize entrainment of liquid and/or solid components of the reactor in the process off-gas.

摘要： Disclosed is a process for the preparation of 1,4-cyclohexanedimethanol from terephthalic acid. Terephthalic acid is esterified with (4-methylcyclohexyl)methanol and the terephthalate ester hydrogenated to 1,4-cyclohexanedimethanol in a 2-stage process. The (4-methylcyclohexyl)methanol that is formed during the hydrogenation step is recycled to the esterification reaction. After removal of the (4- methylcyclohexyl)methanol from the crude hydrogenation product, the 1,4- cyclohexanedimethanol product can be recovered and purified by a phase separation and distillation.

摘要： Disclosed is a process to produce a purified carboxylic acid slurry. The process comprises removing impurities from a crystallized product in a solid liquid displacement zone to form the purified carboxylic acid slurry. The purified carboxylic acid slurry is further cooled in a cooling zone and subsequently filtered and dried in a filtration and drying zone. The process produces purified carboxylic acid product having good color and low impurity levels without the use of purification steps like hydrogenation or filtrate purge.

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 1550C, 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 fro about 10 to about 400. The processes provide improved conversion, while reducing the formation of carbon oxides and other by-products.
