Therefore, to investigate the process that oligomeric bishydroxybutyl terephthalate is used as the reaction medium for the esterification of TPA with BD the solubility data of TPA in the reaction system thus obtained is valuable, but there are only a limited solubility data exists for TPA in terephthalic acid-ethylene glycol-esterification system or articles about TPA solution in BD.

Therefore, when oligomeric bishydroxybutyl terephthalate is used as the reaction medium for the esterification of TPA with BD, it is comparatively meaningful to obtain the solubility data of TPA in the reaction system.However,both solubility data of TPA in terephthalic acid-ethylene glycol-esterification system and researches about TPA solution in BD are still scarce so far. ²»ÖªµÀÄãÖÐÎÄÊÇʲôÒâ˼£¬×¨ÒµµÄ֪ʶÎÒÒ²²»ÖªµÀ£¬ÎÒÊÇ×Ô¼ºÀí½â×Å·ÒëµÄ¡£^_^ |
