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

ʻO 3,3',4,4'-Benzophenonetetracarboxylic dianhydride, i kapa ʻia hoʻi ʻo BPTCDA, he hui kemika versatile e loaʻa ana ka hoʻohana nui ʻana i nā ʻoihana like ʻole. ʻO kekahi o kāna hoʻohana nui ʻana ma ke kahua o ka ʻepekema polymer. Hana ʻo BPTCDA ma ke ʻano he monomer koʻikoʻi i ka synthesis o nā polymers hana kiʻekiʻe a me nā copolymers. Hōʻike kēia mau polymers i ke kūpaʻa wela maikaʻi loa, ka ikaika mechanical, a me nā waiwai uila. Loaʻa iā lākou ka hoʻohana ma nā wahi e like me nā composites holomua, nā uhi, nā mea hoʻopili, a me nā mea uila. Ua ʻike ʻia nā polymers i hoʻokumu ʻia e BPTCDA no ko lākou kūʻē ʻana i nā mahana kiʻekiʻe a me nā ʻano ʻino, e kūpono ai lākou no nā ʻoihana aerospace, automotive, a me nā mea uila. Eia kekahi, he kuleana koʻikoʻi ko BPTCDA i ka kemika mea. ʻO kona ʻano kū hoʻokahi a me ka reactivity e lilo ia i mea nui i ka hana ʻana i nā mea hana e like me nā kristal wai, nā semiconductors organik, a me nā hui photochromic. Loaʻa i kēia mau mea nā noi i nā ʻenehana hōʻike, nā mea optical, a me nā sensor. Eia kekahi, hoʻohana nui ʻia ʻo BPTCDA i ka synthesis organik. ʻO kāna mau hui waikawa carboxylic reactive kiʻekiʻe e ʻae i ka hoʻokumu ʻana o nā derivatives like ʻole a me nā hui hana. Hoʻohana nā mea noiʻi ʻO BPTCDA ma ke ʻano he poloka hale e hana i nā molekala organik paʻakikī me nā waiwai i makemake ʻia no nā lāʻau lapaʻau, nā agrochemicals, a me nā kemika kūikawā. Eia kekahi, loaʻa i kēia hui ka pono ma ke kahua o ka catalysis. ʻO kona ʻōnaehana paʻa a me nā hui electron-withdrawing e lilo ia i mea hoʻoulu maikaʻi i kekahi mau hopena, me ka oxidation, ka hōʻemi ʻana, a me ka hoʻokumu ʻana o ka pilina carbon-carbon. Ua hōʻike nā mea hoʻoulu i hoʻokumu ʻia e BPTCDA i ka reactivity i hoʻonui ʻia, ke koho ʻana, a me ke kūpaʻa, e hiki ai ke hoʻololi i nā kemika ʻoi aku ka maikaʻi a me ka hoʻomau. I ka hōʻuluʻulu manaʻo, ʻo 3,3',4,4'-Benzophenonetetracarboxylic dianhydride, a i ʻole BPTCDA, he mau noi koʻikoʻi i ka ʻepekema polymer, ke kemika mea, ka synthesis organik, a me ka catalysis. ʻO kona ʻano kū hoʻokahi a me ka reactivity versatile e lilo ia i hui waiwai no ka hoʻomohala ʻana i nā polymers hana kiʻekiʻe, nā mea hana, a me nā molekala organik paʻakikī. ʻO ka laulā like ʻole o nā noi e hana ai iā BPTCDA i mea koʻikoʻi i ka hoʻolaha ʻana i nā holomua ʻenehana a me ka noiʻi ʻepekema.
