Process for preparing diesters of naphthalenedicarboxylic acids |
摘要 |
A continuous process for preparing a dialkylester of a naphthalenedicarboxylic acid comprising passing a liquid phase reaction mixture comprising a low molecular weight alcohol, a naphthalenedicarboxylic acid and a dialkylester of a naphthalenedicarboxylic acid at an elevated temperature through series arranged reaction zones while introducing a naphthalenedicarboxylic acid and a low molecular weight alcohol to an upstream reaction zone, agitating at least one reaction zone, and removing a liquid product mixture comprising the dialkylester of the naphthalenedicarboxylic acid produced by the reaction of the naphthalenedicarboxylic acid with the low molecular weight alcohol from a downstream reaction zone.
