摘要： Disclosed is a process for preparing two esters by reacting an aldehyde with an alcohol in the presence of a ruthenium complex compound as a catalyst. The process is particularly useful for preparing ethyl acetate and n-butyl acetate, isobutyl acetate, or 2-ethylhexyl acetate in high yield by coupling acetaldehyde with n-butanol, i-butanol, or 2-ethylhexanol.

摘要： Processes for producing terephthalic acid are disclosed, the processes including a step of combining in a reaction medium para-xylene, a solvent comprising water and a saturated organic acid having from 2-4 carbon atoms, and an oxygen-containing gas, at a temperature for example from about 145°C to about 175°C, in the presence of a catalyst composition comprising cobalt, manganese, zirconium, and bromine, wherein the zirconium is present in the reaction medium in an amount, for example, from 1 ppm to 50 ppm with respect to the weight of the liquid in the reaction medium.

摘要： A process for purifying a crude furan 2,5- dicarboxylic acid composition (cFDCA) by hydrogenation of a FDCA composition dissolved in a hydrogenation solvent such as water, and hydrogenating under mild conditions, such as at a temperature within a range of 130°C to 225°C by contacting the solvated FDCA composition with hydrogen in the presence of a hydrogenation catalyst under a hydrogen partial pressure within a range of 10 psi to 900 psi. A product FDCA composition is produced having a low amount of tetrahydrofuran dicarboxylic acid, a low b*, and a low amount of 5-formyl furan-2-carboxylic acid (FFCA).
