什么是对苯

p-Phthaldialdehyde, with CAS number 623-27-8, is an important organic intermediate of aromatic dialdehyde. Its core characteristics include high chemical reactivity and symmetrical structure, as well as the reactivity of aldehyde groups and the stability of benzene rings. Terephthalaldehyde is widely used in fine chemicals, material synthesis and other fields.

P-phenyldiformaldehyde is an important fine chemical raw material downstream of p-xylene. Because of its molecular structure has two active aldehyde groups, terephthalaldehyde can self-polymerize or copolymerize with other monomers to form polymer materials, which are mainly used to synthesize into fluorescent materials, catalyst carriers and other polymer products. 传统的生产方法的p-苯是氯化p-二甲苯，然后水解的作用下硝酸或金属的氧化物。

Synthesis of Polymer Materials (Core Applications)

As a monomer of polyimide resin: p-Phthaldialdehyde is used to synthesize high-temperature resistant and radiation-resistant polyimide films, fibers and composite materials, which are suitable for high-end fields such as aerospace, electronic appliances, and new energy (such as flexible circuit board substrates, high-temperature resistant components of spacecraft).

For epoxy resin curing agent: 4-Formylbenzaldehyde reacts with epoxy resin to form high-performance cured products, enhancing the mechanical strength, heat resistance and corrosion resistance of the material. Terephthalaldehyde is suitable for industrial anti-corrosion coatings and electronic packaging materials. 4-Formylbenzaldehyde is used to prepare conductive polymers, adsorption materials, and fluorescent materials, and is applied in scenarios such as sensors, water treatment, and optical devices.

Fine chemicals and pharmaceutical intermediates

For drug synthesis: 4-Formylbenzaldehyde, as an intermediate for antibacterial and anti-inflammatory drugs, participates in the structural modification of drug molecules and enhances the stability of drug efficacy.

It is used in the synthesis of dyes and pigments: for the synthesis of reactive dyes, fluorescent dyes and aromatic pigments, p-Phthaldialdehyde is suitable for fields such as textile printing and dyeing, ink, and plastic coloring. Terephthalaldehyde features bright colors and is resistant to sunlight and water washing.

Other industrial applications

As a crosslinking agent: p-Phthaldialdehyde is used to modify rubber, plastics and adhesives, enhancing the crosslinking density and durability of the products.
