2-Hydroxyterephthalic acid - Reference Information
| Overview | Based on the research of AB type polymerization monomer by the research team of Zhejiang University of Technology, it is found that 2-hydroxy terephthalic acid has potential application prospects in the preparation of new AB monomers for ordered polymers, such as hydroxyl modified Poly (p-phenylenebenzoxazole) (PBO). And poly (p-phenylene terephthalamide) (PPTA), etc. In addition, as an important organic intermediate, 2-hydroxy terephthalic acid has certain application value in medicine and functional materials. Compared with the bulk product terephthalic acid (TPA), the preparation of HTA is mostly in the laboratory scale research at home and abroad, and there are still no industrial production and commodity reports, therefore, it is of great significance to study the synthesis of HTA and its valuable industrialization route. |
| Use | 2-hydroxyterephthalic acid (HTA) as a BB type polymerization monomer, it can be applied to the modification of high-performance fiber materials-Poly (p-phenylenebenzadiazole) (PBX), which utilizes the hydrogen bond and surface polarity of its hydroxyl groups, the axial compressive and composite bonding properties of the materials were improved. |
