ʻO 2,2-Difluoro-1, ʻo ka waikawa he mea hoʻohuihui. Eia kekahi mau ʻike e pili ana iā ia:

 

Nā waiwai: 2,2-Difluoro-1, fluorid he paʻa keʻokeʻo. ʻO C9H4F2O4 kāna kumu molekala a ʻo kona kaumaha molekala he 200.12g/mol. Paʻa ia ma ka lumi wela a haʻahaʻa ka solubility.

 

Hoʻohana: 2,2-Difluoro-1, hoʻohana ʻia ma ke ʻano he mea maka a me ka reagent i ka noiʻi kemika a me ka synthesis organik. Hiki ke hoʻohana ʻia e synthesize i nā pūhui organik ʻē aʻe, e like me nā intermediates pharmaceutical, pesticides a me nā mea hoʻonaninani.

 

ʻano hoʻomākaukau: 2,2-Difluoro-1, ʻoi aku ka paʻakikī o ka hoʻomākaukau ʻana o ka waikawa. Loaʻa ke ʻano hana maʻamau o ka hoʻomākaukau ʻana ma o ka oxidation o kahi benzodioxene, a ukali ʻia e ka pane ʻana me kahi mea hana fluorinating ma lalo o nā kūlana kūpono e hoʻokomo i kahi atom fluorine.

 

ʻIke palekana: I kēia manawa, aia nā ʻike palekana e pili ana i ka 2,2-Difluoro-1, UV acid. ʻAʻole i aʻo nui ʻia, no laila ʻaʻole maopopo i kona ʻona a me ka pōʻino. I ka wā hoʻohana, pono e hahai i nā kaʻina hana palekana kemika maʻamau e hōʻoia i ka hana palekana, a pale i ka inhalation, pili me ka ʻili a me nā maka. Ma mua o ka hoʻohana ʻana, ʻōlelo ʻia e hoʻomaopopo i ka pepa ʻikepili palekana o ka pūhui me ka kikoʻī a lawe i nā hana pale kūpono e pili ana i kāna loiloi pilikia.
