Beschreibung
Terephthalaldehyde is an aromatic dialdehyde. Theoretically, the two aldehydes of terephthalaldehyde (TPA) are equivalent, so the single or double Schiff base from TPA and d-glucosamine (Glc) may be formed at the same time. It is used as an intermediate for the preparation of dyes and fluorescent whitening agents and in the synthesis of polyimines by reacting with aliphatic diamines. It is also used as a precursor for the preparation of paramagnetic microporous polymeric organic frameworks (POFs) through copolymerization with pyrrole, indole, and carbazole. As a good crosslinking agent, it could used in crosslinked chitosan hydrogel for the selective removal of anionic dyes[1].
