Abstract

Способ выделения 2,6-нафталиндикарбоновой кислоты из ее смеси с 1,8-нафталиндикарбоновой кислотой путем ее экстрагирования органическим растворителем при нагревании с последующим фильтрованием и промывкой, отличающийся тем, что, с целью упрощения процесса, в качестве органического растворителя используют пентанон-3 в 10 - 80-кратном количестве, при этом смесь перед экстрагированием подвергают кипячению в среде пентанона-3 и промывку осуществляют также с помощью пентанона-3.The method of separation of 2,6-naphthalene dicarboxylic acid from its mixture with 1,8-naphthalene dicarboxylic acid by extracting it with an organic solvent when heated, followed by filtration and washing, characterized in that, to simplify the process, pentanone-3 is used as an organic solvent 10 - 80-fold amount, while the mixture before extraction is subjected to boiling in the environment of pentanone-3 and washing is also carried out with the help of pentanone-3.
