| titleOfInvention | Method for producing active ingredients from polyester |
| abstract | A polyester composition containing a 6,6 '-(ethylenedioxy) di-2-naphthoic acid component and another dicarboxylic acid component as a main component and stably recovering the acid in a high yield. Provide a method. A polyester composition containing, as a main component, a 6,6 ′-(ethylenedioxy) di-2-naphthoic acid component represented by the following formula (1) and another dicarboxylic acid component is prepared by the following step ( The acid is recovered by sequentially applying to a) to (c). Step (a): A reaction step of reacting the polyester composition with an alkali metal hydroxide or the like in the presence of a solvent having a solubility parameter (SP value) of 11 or more. Step (b): A step of obtaining a metal salt of 6,6 ′-(ethylenedioxy) di-2-naphthoic acid from the reaction product in step (a). Step (c): 6,6 ′-(ethylenedioxy) di-2-naphthoic acid metal salt obtained in step (b) is reacted with an acid to give 6,6 ′-(ethylenedioxy) A step of obtaining di-2-naphthoic acid.
