Application | 2, 5-dihydroxyterephthalic acid is an organic synthesis intermediate and pharmaceutical intermediate, can be used in laboratory research and development process and chemical production process. |
Application | 2, 5-dihydroxyterephthalic acid (DHTA) is a very important monomer for the synthesis of PIPD fiber, it plays an important role in organic synthesis. The yield and purity of DHTA directly affect the polymerization process of PIPD fiber. 2, 5-dihydroxyterephthalic acid is used in organic synthesis. |
preparation | under alkaline conditions, 5-dihaloterephthalic acid is contacted with a source of copper and a ligand coordinated to copper, thereby producing 2, 5-dihydroxyterephthalic acid in high yield and purity. |
