Hoʻolauna

ʻO ka 4-Amino-3,5-dibromobenzotrifluoride he mea hoʻohuihui mea ola me ke ʻano kemika C7H4Br2F3N. ʻO kēia ka wehewehe ʻana o kona ʻano, hoʻohana, hana a me ka ʻike palekana:

 

ʻAno:

-Ke ʻano: kala ʻole a i ʻole melemele māmā

-Solubility: Hiki ke hoʻoheheʻe ʻia e like me ka ethanol a me ka dimethylformamide

-kahi hoʻoheheʻe: ma kahi o 115-117 ℃

-Pila paila: ma kahi o 285 ℃

 

E hoʻohana:

Loaʻa i ka 4-Amino-3,5-dibromobenzotrifluoride kekahi waiwai noi a hoʻohana pinepine ʻia i nā ʻano aʻe:

-Ma ke ʻano he waena i ka synthesis organik, hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā pūhui ʻē aʻe, e like me nā lāʻau lapaʻau, pesticides a me nā meaʻala.

-I ka noiʻi kemika, hiki ke hoʻohana ʻia ma ke ʻano he reagent no ka hopena deprotection.

 

Kaʻina hoʻomākaukau:

Hiki ke hoʻomākaukau ʻia ka 4-Amino-3,5-dibromobenzotrifluoride e nā ʻanuʻu aʻe:

Ua hoʻohana ʻia ka 1.3,5-dibromobenzoic acid i mea maka e hoʻomākaukau ai i ka ester 3,5-dibromobenzoic acid e ka hopena acidification.

Hoʻopili ʻia ka 2.3,5-dibromobenzoic acid ester me ka pūhui nitrogen i ka decarboxylate e hoʻoulu ai i ka 3,5-dibromobenzene acetyl chloride.

3. e hana i ka 3,5-dibromobenzotrifluoromethane me 3,5-dibromobenzotrifluoride e hana i ka 4-Amino-3,5-dibromobenzotrifluoride.

4. Hiki ke loaʻa ka huahana maʻemaʻe ma ka crystallization a i ʻole nā ​​​​ʻano hoʻomaʻemaʻe ʻē aʻe.

 

ʻIke palekana:

- Pono ka 4-Amino-3,5-dibromobenzotrifluoride e hana i nā hana palekana i ka wā o ka hana a me ka mālama ʻana e pale aku i ka pili ʻana me ka ʻili a me nā maka.

-a no ka pale ʻana i ka inhalation a i ʻole ingestion.

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

-Inā loaʻa kahi ulia pōpilikia a pili ʻole paha, holoi koke me ka wai a ʻimi i ka lāʻau lapaʻau.

-I ka lawelawe ʻana i ka pūhui, e ʻoluʻolu e hahai i nā kaʻina hana palekana.
