3,3′,4,4′-Bifeniltetracarboxilico dianidride

Descrizione:

3,3′,4,4′-Bifeniltetracarboxilico dianidride, con il numero CAS 2420-87-3, è un composto chimico noto per il suo ruolo come precursore di polimeri ad alte prestazioni. Questo dianidrido presenta due unità di bifenile collegate da quattro gruppi acidi carbossilici che sono stati convertiti in forme di anidride, risultando in una struttura rigida e piana. È caratterizzato dalla sua alta stabilità termica, eccellenti proprietà meccaniche e resistenza a solventi e sostanze chimiche, rendendolo adatto per applicazioni in materiali avanzati, in particolare nella produzione di poliammidi. Il composto presenta tipicamente un alto punto di fusione e bassa solubilità in solventi organici comuni, il che può complicare il processo ma contribuisce anche alla sua robustezza nelle applicazioni finali. Inoltre, può subire reazioni di polimerizzazione per formare resine termoindurenti, utilizzate in elettronica, aerospaziale e altre industrie ad alta tecnologia. In generale, 3,3′,4,4′-Bifeniltetracarboxilico dianidride è apprezzato per le sue uniche proprietà strutturali e versatilità nella scienza dei materiali.

4,4'-Biphthalic anhydride

CAS: 2420-87-3

4,4'-Biphthalic anhydride is a dianhydride that can be reacted with amines to form amides. It is a colorless, water-soluble solid that has been used in the production of polyimides and other polymers. 4,4'-Biphthalic anhydride reacts with hydrochloric acid to form a molecule of water vapor and the corresponding salt. This compound also reacts with hydroxyl groups to produce carbonyl groups. 4,4'-Biphthalic anhydride has a thermal expansion coefficient of 7 x 10^-5 K^-1, which is greater than that of most organic compounds. This high expansion coefficient means that it can be used in applications where low thermal expansion coefficients are needed.
