Application: p-benzaldehyde is mainly used in dye, fluorescent brightener, medicine, perfume and other industries. It is an important raw material for organic synthesis and fine chemical industry. At the same time, because it has two active aldehyde groups, it can not only self polymerize, but also copolymerize with other monomers to form polymer compounds with various properties. It is an important monomer for the synthesis of polymer materials.

Properties

P-benzaldehyde is an important fine chemical raw material downstream of p-xylene. Because there are two active aldehyde groups in its molecular structure, it can self polymerize or copolymerize with other monomers to form polymer materials. It is mainly used to synthesize fluorescent materials, catalyst carriers and other polymer products. The traditional production method of p-benzaldehyde is to chlorinate p-xylene and then hydrolyze it under the action of nitric acid or metal oxide.
