Industrial Applications of 4,4'-Oxybisbenzoic acid
| Industry | Application | Process |
|---|---|---|
| Polymers | Synthesis of high-performance engineering plastics, such as polyaryletherketones (PAEK) | Used as a dicarboxylic acid monomer in nucleophilic substitution polycondensation with difluoroarenes or dihaloarenes to produce high-temperature-resistant, high-strength polymers |
| Pharmaceutical Intermediates | Synthesis of specific drug molecular scaffolds | Applied as an aromatic carboxylic acid structural unit in functional group transformations—such as amidation and esterification—to construct complex molecules |
| Liquid Crystal Materials | Preparation of liquid crystalline polymers (LCPs) or small-molecule liquid crystal compounds | Employed as a rigid mesogenic linking unit, incorporated into main chains or side chains via ester or amide bonds to modulate liquid crystalline phase behavior |
| Catalyst Ligands | Construction of metal–organic frameworks (MOFs) or porous coordination polymers | Utilized as a multidentate carboxylate ligand in self-assembly with transition metal ions to form crystalline materials exhibiting catalytic or adsorptive properties |
| Electronic Chemicals | Preparation of precursors for insulating films or dielectric materials | Processed into thermally stable thin films for microelectronic device packaging via solution coating or chemical vapor deposition |
