Hoʻolauna

ʻO ka 2-Chloro-5-fluorobenzoic acid he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:

 

ʻAno maikaʻi:

- Ke ʻano: ʻAʻole waihoʻoluʻu i nā kristal melemele māmā a i ʻole nā ​​pauka crystalline.

- Hoʻoheheʻe: hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik, hiki ke hoʻoheheʻe iki i ka wai.

 

E hoʻohana:

- Hoʻohana pinepine ʻia ka 2-Chloro-5-fluorobenzoic acid ma ke ʻano he mea waena i ka synthesis organik.

- Hiki ke hoʻohana ʻia e like me ka organik synthesis reagent a me ka catalyst.

 

Hanana:

Hoʻomākaukau ʻia ka 2-Chloro-5-fluorobenzoic acid e:

Hoʻopili ʻia ka waiʻona 2-chloro-5-fluorobenzyl me ka sodium hydroxide (NaOH) a i ʻole potassium hydroxide (KOH) no ka loaʻa ʻana o ka paʻakai paʻakai paʻakai a i ʻole ka paʻakai potassium.

Hoʻopili ʻia ia e ka waika hydrochloric e hana i ka 2-chloro-5-fluorobenzoic acid.

 

ʻIke palekana:

- ʻO 2-Chloro-5-fluorobenzoic acid he mea hiki ke hoʻopau ʻia a pono e pale ʻia mai ka hoʻopili ʻana me nā mea hoʻoneʻe ikaika a i ʻole oxygen.

- E hoʻohana i nā mea pale kūpono, e like me nā mīkina lima, nā aniani, a me nā lole pale, i ka wā e lawelawe ai a lawelawe paha.

- E hōʻalo i ka hanu ʻana i kona lepo a i ʻole ka hopena a hana ma kahi wahi i hoʻoluʻu maikaʻi ʻia.

- E mālama i nā wela kiʻekiʻe, ke ahi, a me ka lā pololei, a hoʻopaʻa paʻa i ka pahu.
