Hoʻolauna
ʻO ka 3,5-Difluorobenzoic acid he mea hoʻohui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o kēia pūhui:
ʻAno maikaʻi:
- 3,5-Difluorobenzoic acid he aniani kala ʻole a i ʻole ka pauka crystalline keʻokeʻo.
- Aneane hiki ʻole ke hoʻoheheʻe ʻia i loko o ka wai ma ke ana wela, akā hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol, ether, etc.
- He ʻala ʻala koʻikoʻi ka pūhui a he ʻino.
E hoʻohana:
- Hoʻohana nui ʻia ka 3,5-Difluorobenzoic acid ma ke ʻano he koʻikoʻi koʻikoʻi a me ka reagent i ka synthesis organik.
- Hiki ke hoʻohana ʻia ka pūhui i ka hopena fluorination a me ka hoʻohui ʻana o nā mea ʻala i nā hopena synthesis organik.
Hanana:
- Hiki ke loaʻa ke ʻano hoʻomākaukau o ka 3,5-difluorobenzoic acid ma ka hopena o ka benzoic acid a me ka hydrofluoric acid i mua o kahi catalyst.
- Ma lalo o nā kūlana hopena, hui pū ʻia ka waikawa benzoic me ka waika hydrofluoric a hoʻomehana ʻia, a lawe ʻia ka hopena ma lalo o ka hana a kahi catalyst e hoʻoulu ai i ka waikawa 3,5-difluorobenzoic.
ʻIke palekana:
- ʻO ka 3,5-Difluorobenzoic acid he mea hoʻonāukiuki e hiki ai ke hoʻoulu i ka huhū i ka piliʻana me kaʻili a me nā maka, a pono e hoʻohanaʻia nā mea pale pilikino kūpono.
- Pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā mea hoʻoheheʻe ikaika a me nā mea alkaline ikaika i ka wā e hoʻohana ai a mālama ʻia paha kēia pūhui e pale ai i nā hopena pōʻino.
- Hōʻalo i ka honi ʻana i ka mahu nui o 3,5-difluorobenzoic acid, no ka mea, he ʻala ʻala.
