Hoʻolauna

ʻO ka 2-Fluoro-5-nitrobenzoic acid he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kekahi o kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana.

 

ʻAno maikaʻi:

- Ke ʻano: 2-Fluoro-5-nitrobenzoic acid he kala ʻole i ka crystalline melemele māmā a i ʻole ka pauka.

- Aneane hiki ʻole ke hoʻoheheʻe ʻia i loko o ka wai ma ke ana wela, hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me nā alcohols, ethers, etc.

 

E hoʻohana:

- Hiki ke hoʻohana ʻia ka 2-Fluoro-5-nitrobenzoic acid ma ke ʻano he mea maka a i ʻole waena i ka synthesis organik.

 

Hanana:

- Nui nā ʻano hoʻomākaukau no ka 2-fluoro-5-nitrobenzoic acid, a ʻo kekahi o nā ʻano maʻamau ma o ka hoʻololi ʻana o ka nitrobenzene. I ka hana kiko'ī, hiki ke hoʻokomo ʻia nā ʻātoma fluorine i loko o ka mole nitrobenzene, a laila hiki ke hoʻokō ʻia ka hopena hoʻohaʻahaʻa acid-catalyzed ma lalo o nā kūlana kūpono e loaʻa ai ka huahana hope.

 

ʻIke palekana:

- ʻO ka 2-fluoro-5-nitrobenzoic acid he mea hoʻohuihui kino weliweli, a pono e hoʻohana a mālama pono ʻia.

- Hiki ke hoʻonāukiuki a me ka pōʻino i ke kino o ke kanaka, a pono e mālama ʻia e pale i ka ʻike pololei ʻana i ka ʻili, nā maka, a me ka ʻōpū hanu ke hoʻopā ʻia.

- Pono e mālama pono i ka wā o ka hana, e like me ke komo ʻana i nā aniani pale, nā maka, a me nā mīkina lima pale.

- Pono ka lawelawe ʻana a me ka hoʻokuʻu ʻana i nā mea i nā kānāwai kūloko kūpono a ʻaʻole pono e hoʻolei ʻia a hoʻolei ʻia i loko o ke kaiapuni.
