1,4,5,8-Naphthalenetetracarboxylic dianhydride / NTDA cas: 81-30-1

Ibisobanuro bigufi:

1,4,5,8-naphthalene tetracarboxylic anhydride, bakunze kwita NTA, ni ibintu byera bya kristaline yera hamwe na formula ya chimique C12H4O5.Yakozwe yitonze ikoresheje inzira zuzuye kugirango irebe ubuziranenge bwayo nubuziranenge.NTA ikoreshwa cyane nkibikoresho fatizo muguhuza ibice bitandukanye kama, bigira uruhare mugutezimbere inganda nyinshi zingenzi.

Ibicuruzwa

- Ibyiza bya fiziki na chimique: NTA ifite uburemere bwa molekile ya 244.16 g / mol hamwe no gushonga kwa 352-358°C. Irerekana imbaraga zidasanzwe mumashanyarazi nka chloroform, Ethyl acetate, na benzene.Byongeye kandi, irerekana ituze ryiza mubihe bisanzwe, ryemerera kubika no gutwara nta kwangirika gukomeye.

- Gusaba: NTA isanga ikoreshwa mubikorwa bitandukanye byinganda, harimo imiti, amarangi, na plastiki.Mu rwego rwa farumasi, ikora nk'urwego rukomeye mu guhuza imiti, igira uruhare mu iterambere ry'ubuvuzi bushya.Ibikorwa byayo byinshi kandi bihuza bituma iba ikintu cyiza mugukora amabara meza cyane, atanga amabara adasanzwe.Byongeye kandi, NTA ikoreshwa nka monomer muri synthesis ya polymers yihariye na resin, byongera imikorere yabo hamwe nigihe kirekire.

- Ibitekerezo byumutekano: Iyo ukoresheje 1,4,5,8-naphthalene tetracarboxylic anhydride, birakenewe kubahiriza ingamba zisanzwe zumutekano.Uru ruganda rugomba kubikwa ahantu hakonje, humye, kure yumuriro ugurumana cyangwa inkomoko.Guhumeka neza ni ngombwa mugihe cyo gukoresha kugirango wirinde guhumeka umwuka wose ushobora kuba.Kimwe n’ibintu byose bya shimi, ni ngombwa kwambara ibikoresho byabigenewe bikingira umuntu, harimo uturindantoki hamwe n’amadarubindi, kugira ngo ugabanye imibonano itaziguye kandi umutekano wawe.

Mu gusoza, 1,4,5,8-naphthalene tetracarboxylic anhydride ni imiti yingirakamaro ikora nkibintu bitandukanye mubikorwa bitandukanye.Imiterere yihariye hamwe nibisabwa byinshi bituma iba ikintu cyingenzi muguhuza ibinyabuzima, imiti, amarangi, na plastiki.Twiyemeje kuguha NTA nziza cyane, yakozwe neza kandi yubahiriza amahame yinganda.
