Hoʻolauna
ʻO ka 2,5-bis(trifluoromethyl) benzoic acid he mea hoʻohuihui me ke ʻano kemika C9H4F6O2. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.
ʻAno:
- 2,5-bis(trifluoromethyl)benzoic acid he kala ʻole i ka ʻeleʻele melemele ʻeleʻele a i ʻole ka pauka paʻa.
-Aneane hiki ʻole ke hoʻoheheʻe ʻia i loko o ka wai ma ka lumi wela, akā hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ether a me ka dichloromethane.
-He ʻala ʻino ikaika kona.
E hoʻohana:
- ʻO 2,5-bis(trifluoromethyl) benzoic acid he mea hoʻohana maʻamau i ka synthesis organik, hiki ke hoʻohana ʻia e synthesize i nā pūhui e like me nā lāʻau lapaʻau, nā meaʻala a me nā mea.
-Hiki ke hoʻohana ʻia ma ke ʻano he catalyst no nā hopena synthesis organik, e like me nā hopena aromatization a me nā hopena carboxylation.
-Ma waho aʻe, hoʻohana ʻia no ka hoʻomākaukau ʻana i nā mea uila a me ka hoʻololi ʻana o ka ʻili o nā mea optical.
Kaʻina hoʻomākaukau:
- Hiki ke synthesized ka 2,5-bis(trifluoromethyl) benzoic acid ma ka hana ʻana i ka 2,5-difluoromethylbenzoic acid me ka trifluoromethylating reagent (e like me trifluoromethyl chloride).
-Hoʻohana maʻamau kēia pane ma lalo o kahi lewa inert a hoʻohana i ka catalyst ma lalo o nā kūlana acidic a kumu.
ʻIke palekana:
- 2,5-bis(trifluoromethyl)benzoic acid he mea ʻino loa a hiki ke hoʻoulu i ka huhū nui a me ka pōʻino ke pili me ka ʻili a me nā maka.
-E hoʻohana i nā mea pale kūpono e like me nā mīkina lima, nā maka aniani a me nā lole pale i ka wā o ka hana.
- Pono e mālama ʻia kēia pūhui mai ke ahi a me nā mea hoʻoheheʻe, a waiho ʻia i loko o kahi pahu i hoʻopaʻa ʻia e pale aku i ka pili ʻana me ka ea a me ka wai.
- Pono e hahai ʻia nā hana palekana kemika kūpono i ka wā o ka hoʻohana ʻana a me ka mālama ʻana.
