Product Details

Products Description of Terephthalaldehyde CAS#623-27-8

Terephthalaldehyde is an important fine chemical raw material downstream of paraxylene. Because it has two active aldehyde groups in its molecular structure, it can self-polymerize or copolymerize with other monomers to form polymer materials, which are mainly used to synthesize fluorescent materials. Materials, catalyst carriers and other high molecular polymer products. The traditional production method of terephthalaldehyde is through chlorination of p-xylene and subsequent hydrolysis under the action of nitric acid or metal oxides.
