Terephthalaldehyde Cas623-27-8 99%

는 무엇입 Terephthalaldehyde

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. 전통적인 생산 방법 p-벤즈알데히드가에 의해 염화의 p-크실렌,다음 가수분해에서 작업의 질산이나 금속 산화물.
