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

- Nā Waiwai Kino a Kemika: Loaʻa i ka NTA ke kaumaha molekala o 244.16 g/mol a me kahi helu heheʻe o 352-358°C. Hōʻike ia i ka solubility maikaʻi loa i nā mea hoʻoheheʻe organik e like me chloroform, ethyl acetate, a me benzene.Eia kekahi, hōʻike ia i ka paʻa maikaʻi ma lalo o nā kūlana maʻamau, e ʻae ana i ka mālama ʻana a me ka lawe ʻana me ka ʻole o ka hōʻino nui ʻana.

- Nā noi: ʻike ʻo NTA i ka noi ma nā ʻano ʻoihana like ʻole, me nā lāʻau lapaʻau, nā mea ʻulaʻula, a me nā plastics.I ka ʻāpana lāʻau lapaʻau, lawelawe ia ma ke ʻano he koʻikoʻi koʻikoʻi i ka synthesis o nā lāʻau lapaʻau, e hāʻawi ana i ka hoʻomohala ʻana i nā lāʻau lapaʻau hou.ʻO kona ʻano kiʻekiʻe a me ka hoʻohālikelike ʻana e lilo ia i mea kūpono i ka hana ʻana i nā mea pena kiʻekiʻe, e hāʻawi ana i nā waiwai kala ʻokoʻa.Eia kekahi, hoʻohana ʻia ka NTA ma ke ʻano he monomer i ka synthesis o nā polymers kūikawā a me nā resins, e hoʻonui ana i kā lākou hana holoʻokoʻa a me ka lōʻihi.

- Noʻonoʻo palekana: I ka lawelawe ʻana i ka 1,4,5,8-naphthalene tetracarboxylic anhydride, pono e nānā i nā ʻano palekana maʻamau.Pono e mālama ʻia kēia mea hoʻohui i kahi maloʻo a maloʻo, ma kahi mamao o nā lapalapa ahi a i ʻole nā ​​kumu ʻā.Pono ka ea kūpono i ka wā o ka hoʻohana ʻana no ka pale ʻana i ka inhalation o nā mahu.E like me nā mea kemika, he mea koʻikoʻi ke komo ʻana i nā lako pale pilikino kūpono, me nā mīkina lima a me nā maka aniani, e hōʻemi i ka pilina pololei a hōʻoia i ka palekana pilikino.

I ka hopena, ʻo 1,4,5,8-naphthalene tetracarboxylic anhydride he mea hoʻohui kemika waiwai e lawelawe nei ma ke ʻano he mea hoʻohui i nā ʻoihana like ʻole.ʻO kāna mau waiwai kūʻokoʻa a me kāna mau noi nui e lilo ia i mea koʻikoʻi i ka synthesis o nā pūhui organik, nā lāʻau lapaʻau, nā dyes, a me nā plastics.Hoʻolaʻa mākou i ka hāʻawi ʻana iā ʻoe i ka NTA kiʻekiʻe loa, i hana ʻia me ka pololei a me ka hoʻokō ʻana i nā kūlana ʻoihana.
