Terephthalaldehyde CAS 623-27-8

Phthalaldehyde is an important fine chemical raw material downstream of p-xylene. Due to the presence of two active aldehyde groups in its molecular structure, it can self polymerize or copolymerize with other monomers to form polymer materials, mainly used for the synthesis of fluorescent materials, catalyst carriers, and other polymer products. The traditional production method for benzaldehyde is to chlorinate p-xylene and then hydrolyze it in the presence of nitric acid or metal oxides.
