Hoʻolauna

ʻO 2-nitroaniline, i ʻike ʻia ʻo O-nitroaniline, he mea hoʻohui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 2-nitroaniline.

 

ʻAno maikaʻi:

- Ke ʻano: 2-nitroaniline he aniani melemele a i ʻole ka pauka crystalline.

- Hiki ke hoʻoheheʻe ʻia: hiki ke hoʻoheheʻe ʻia ka 2-nitroaniline i ka ethanol, ether a me benzene, a hiki ke hoʻoheheʻe iki ʻia i ka wai.

 

E hoʻohana:

- Ka hana ʻana o nā kala: hiki ke hoʻohana ʻia ka 2-nitroaniline i ka synthesis o nā intermediates dye, e like me ka hoʻomākaukau ʻana o ka aniline melemele.

- Nā mea pahū: 2-nitroaniline nā waiwai pahū a hiki ke hoʻohana ʻia ma ke ʻano he mea maka no nā mea pahū a me nā pyrotechnics.

 

Hanana:

- Hiki ke hoʻomākaukau ʻia ka 2-nitroaniline e ka hopena o ka aniline me ka waikawa nitric. Hoʻohana maʻamau ʻia nā kūlana hopena ma nā mahana haʻahaʻa a hoʻohana ʻia ka sulfuric acid ma ke ʻano he catalyst.

- Ka hoohalike ana: C6H5NH2 + HNO3 -> C6H6N2O2 + H2O

 

ʻIke palekana:

- ʻO 2-Nitroaniline kahi pūhui pahū i hiki ke kumu ma muli o ka ʻike ʻana i ka ʻā a i ʻole nā ​​wela kiʻekiʻe. Pono e mālama ʻia mai nā lapalapa ahi, nā kumu wela, nā uila uila, etc.

- E hoʻohana i nā makaaniani pale a me nā mīkina lima i ka wā e hana ai e pale aku i ka hanu ʻana i ka lepo a i ʻole ke pā ʻana i ka ʻili, a pale i ka ʻai ʻana.

- I ka hui ʻana me 2-nitroaniline, holoi koke me ka wai nui a ʻimi i ka lāʻau lapaʻau no ka mālama ʻana.
