摘要： Disclosed is a method for producing an optically active ester by highly selectively esterifying one enantiomer of a racemic carboxylic acid, while producing an optically active carboxylic acid which is the other enantiomer. An optically active ester is produced while producing an optically active carboxylic acid at the same time by reacting a racemic carboxylic acid with a specific alcohol or phenol derivative in the presence of benzoic anhydride or a derivative thereof and a catalyst such as tetramisole or benzotetramisole, thereby selectively esterifying one enantiomer of the racemic carboxylic acid.

摘要： The process for preparing polyethylene naphthalate according to the invention is intended to obtain polyethylene naphthalate having a low impurity content from naphthalenedicarboxylic acid containing impurities. This process comprises the steps of: mixing crude naphthalenedicarboxylic acid and an ethylene glycol aqueous solution, heating the resulting mixture to esterify a part of the naphthalenedicarboxylic acid and thereby give a naphthalenedicarboxylic acid ester and dissolving the naphthalenedicarboxylic acid ester in the ethylene glycol aqueous solution; then contacting impurities, which are contained in the crude naphthalenedicarboxylic acid and capable of being hydrogenated, with hydrogen in the presence of a hydrogenation catalyst to hydrogenate the impurities and dissolving the hydrogenated impurities in the ethylene glycol aqueous solution; and subsequently crystallizing the naphthalenedicarboxylic acid ester, separating the resulting crystals from the ethylene glycol aqueous solution and polycondensing the resulting naphthalenedicarboxylic acid ester. The method of purifying crude naphthalenedicarboxylic acid is intended to obtain naphthalenedicarboxylic acid and a naphthalenedicarboxylic acid ester having a low content of aldehydes from naphthalenedicarboxylic acid containing aldehydes. This method comprises the steps of: mixing crude naphthalenedicarboxylic acid and an alcohol aqueous solution, heating the resulting mixture to esterify a part of the naphthalenedicarboxylic acid and thereby give a naphthalenedicarboxylic acid ester and dissolving the naphthalenedicarboxylic acid ester in the alcohol aqueous solution; then contacting aldehydes, which are contained in the crude naphthalenedicarboxylic acid, with a sulfite to give aldehyde adducts and dissolving the aldehyde adducts in the alcohol aqueous solution; and subsequently crystallizing the naphthalenedicarboxylic acid and the naphthalenedicarboxylic acid ester and separating them from the alcohol aqueous solution.

摘要： A method is provided to improve the quality of recycle of certain residues by modifying the separation of alkanes and alkane-like materials and carbonyl-containing impurities from the recycle during the manufacture of acetic acid by the carbonylation of methanol. The improvement comprises partitioning the residues by the addition of water obtained from aqueous streams containing up to 50 wt.% acetic acid and which have been treated in a catalytic distillation unit to react the acetic acid with methanol to form recyclable methyl acetate and water and wherein the water is separated from the organics by distillation.

摘要： Methods for forming ammonium salts of C4 diacids in a fermentation process with removal of divalent metal carbonate salts are disclosed. The pH of fermentation broths for production of C4 diacids is controlled by adding alkaline oxygen containing calcium or magnesium compounds, which forms divalent metal salts of the diacids. The divalent metal salts of the diacids are substituted with ammonium by introduction of ammonium salts at elevated temperature and pressure forming soluble ammonium salts thereof. C02 or bicarbonate is simultaneously added to the fermentation media at the elevated temperature and pressure. Reducing the temperature and pressure forms insoluble divalent metal carbonate salts that are separated from the solubilized ammonium diacid salts. The recovered carbonate salts can be recycled as pH control materials in subsequent fermentations. The solubilized ammonium diacid salts may form the derivatives N-methyl-2-pyrrolidone (NMP) gamma-butyrolactone (GBL) and 1,4-butane-diol (BDO) in single pot reactions.
