3,3′,4,4′-Benzophenonetetracarboxylic dianhydride CAS:2421-28-5

"3,3', 4,4'-Benzophenonetetracarboxylic dianhydride, yomwe imatchedwanso BPTCDA, ndi mankhwala ogwiritsidwa ntchito kwambiri omwe amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Chimodzi mwa ntchito zake zazikulu ndi sayansi ya polima. BPTCDA imagwira ntchito ngati monomer yofunika kwambiri popanga ma polima ndi ma copolymers ogwira ntchito kwambiri. Ma polima awa amasonyeza kukhazikika kwa kutentha, mphamvu zamakanika, ndi mphamvu zamagetsi. Amagwiritsidwa ntchito m'malo monga zophatikizika zapamwamba, zokutira, zomatira, ndi zida zamagetsi. Ma polima opangidwa ndi BPTCDA amadziwika kuti amakana kutentha kwambiri komanso malo ovuta, zomwe zimapangitsa kuti akhale oyenera mafakitale amlengalenga, magalimoto, ndi zamagetsi. Kuphatikiza apo, BPTCDA imagwira ntchito yofunika kwambiri mu chemistry yazinthu. Kapangidwe kake kapadera ndi reactivity yake zimapangitsa kuti ikhale gawo lofunikira popanga zinthu zogwira ntchito monga makristalo amadzimadzi, ma semiconductors achilengedwe, ndi mankhwala a photochromic. Zipangizozi zimagwiritsidwa ntchito muukadaulo wowonetsera, zida zowunikira, ndi masensa. Kuphatikiza apo, BPTCDA imagwiritsidwa ntchito kwambiri popanga zinthu zachilengedwe. Magulu ake a carboxylic acid omwe amagwira ntchito kwambiri amalola kupanga zinthu zosiyanasiyana zotumphukira ndi mankhwala ogwirira ntchito. Ofufuza amagwiritsa ntchito BPTCDA monga chomangira chopangira mamolekyu ovuta achilengedwe okhala ndi zinthu zofunika pa mankhwala, mankhwala a agrochemicals, ndi mankhwala apadera. Kuphatikiza apo, mankhwalawa amapeza ntchito yothandiza pakupanga ma catalysis. Chimango chake cholimba ndi magulu ochotsa ma elekitironi zimapangitsa kuti ikhale chothandizira chogwira ntchito m'njira zingapo, kuphatikizapo kusungunuka, kuchepetsa, ndi kupanga ma bond a carbon-carbon. Ma catalysts ochokera ku BPTCDA awonetsa kusinthika kwakukulu, kusankha, ndi kukhazikika, zomwe zimathandiza kusintha kwa mankhwala kogwira mtima komanso kokhazikika. Mwachidule, 3,3', 4,4'-Benzophenonetetracarboxylic dianhydride, kapena BPTCDA, ili ndi ntchito zofunika kwambiri mu sayansi ya polima, chemistry ya zinthu, kapangidwe ka organic, ndi catalysis. Kapangidwe kake kapadera komanso kusinthasintha kwake kumapangitsa kuti ikhale chophatikiza chofunikira popanga ma polima ogwira ntchito kwambiri, zinthu zogwirira ntchito, ndi ma molekyulu ovuta achilengedwe. Mitundu yosiyanasiyana ya ntchito imapangitsa BPTCDA kukhala gawo lofunikira pakupititsa patsogolo kupita patsogolo kwaukadaulo ndi kafukufuku wasayansi.
