Hoʻolauna

2,5-Difluorobenzaldehyde. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, hana hana a me ka ʻike palekana:

 

ʻAno maikaʻi:

ʻO 2,5-Difluorobenzaldehyde he wai kalamele ʻole i ka māmā me kahi kaha kuni ikaika, ʻala ʻala i ka lumi wela. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai akā hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol, toluene, etc.

 

E hoʻohana:

ʻO 2,5-Difluorobenzaldehyde ka nui o nā noi i ka synthesis organik. Hiki ke hoʻohana ʻia ma ke ʻano he precursor no ka synthesis of aromatic compounds, paraphthalenedione derivatives, a me nā moleke bioactive. Hiki ke hoʻohana ʻia i ka synthesis o nā organometallic complexes, nā uhi hana kiʻekiʻe a me nā kala.

 

Hanana:

Hiki ke hoʻomākaukau ʻia ka 2,5-difluorobenzaldehyde e ka hopena o benzaldehyde a me ka hydrogen fluoride. Hana ʻia kēia hopena ma lalo o nā kūlana acidic a hiki ke hoʻokō ʻia me ka hoʻohana ʻana i ka waika hydrofluoric i kumu o ka hydrogen fluoride.

 

ʻIke palekana:

Pono e mālama i ka mālama ʻana i ka 2,5-difluorobenzaldehyde. He mea hoʻonāukiuki i ka ʻili, nā maka a me ka ʻōpū hanu. Pono e ʻaʻahu ʻia nā aniani pale kemika, nā mīkina lima a me nā lole pale a pale ʻia ka hoʻopili pololei ʻana. Inā komo i loko o kou mau maka a i ʻole ka ʻili, holoi koke me ka wai nui a ʻimi koke i ka lāʻau lapaʻau. I ka wā o ka hana, pono e mālama ʻia mai nā kumu ahi a pale aku i ka uahi a me nā mahu e pale aku i ke ahi a me ka pahū.

 

He hoʻolauna pōkole kēia i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 2,5-difluorobenzaldehyde. Inā pono, e hōʻoia ʻoe e hoʻomaopopo a hahai i nā lula palekana a me ke alakaʻi ʻana o ka lab ma mua o ka lawelawe ʻana a hoʻohana.
