Hoʻolauna
ʻO ka 3,5-Difluoropyridine he mea hoʻohui kino me ke ʻano kemika C5H3F2N. ʻO kēia ka wehewehe ʻana o kona ʻano, hoʻohana, hana a me ka ʻike palekana:
ʻAno:
-Nani: wai kala ʻole
-Ka helu hehee:-53 ℃
-Pila paila: 114-116 ℃
-Ka mānoanoa: 1.32g/cm³
-Solubility: Hiki ke hoʻoheheʻe ʻia i ka wai a me ka hapa nui o nā mea hoʻoheheʻe organik.
E hoʻohana:
- Hoʻohana nui ʻia ka 3,5-Difluoropyridine ma ke ʻano he kumu waiwai nui i ka synthesis organik. Hiki ke hoʻohana ʻia i ka synthesis o nā pesticides, pharmaceuticals a me nā pūhui organik ʻē aʻe.
- Hiki ke hoʻohana ʻia e like me ka reagent kemika no ka nānā ʻana a me ka noiʻi kemika.
Kaʻina hoʻomākaukau:
Hoʻohana pinepine ʻia ka hoʻomākaukau ʻana o 3,5-Difluoropyridine e kekahi o kēia mau ʻano:
-E hoʻomaka ana mai pyrimidine, e hoʻokomo mua i nā ʻātoma fluorine ma pyrimidine, a laila e hoʻohui i nā ʻātoma fluorine i nā kūlana 3 a me 5.
-loaʻa mai 3,5-difluoro chloropyrimidine a i ʻole 3,5-difluoro bromopyrimidine pane.
ʻIke palekana:
- 3,5-Difluoropyridine hiki ke pōʻino i ke kino kanaka. Hiki i ka ʻike ʻana i ka mea hoʻohui ke hoʻonāukiuki i ka maka a me ka ʻili. No laila, pono e lawe i nā mea palekana e pono ai, e like me ke komo ʻana i nā mīkina lima kūpono, nā goggles a me nā lole pale.
-I ka hoʻopā ʻana a i ʻole ka inhalation o 3,5-Difluoropyridine, pono e hoʻomaʻemaʻe koke ʻia ka wahi i hoʻopili ʻia a ʻōlelo ʻia e ke kauka.
-I ka mālama ʻana a me ka mālama ʻana, pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā oxidants ikaika a me nā waikawa ikaika.
E ʻoluʻolu e hoʻomaopopo i ka hoʻohana ʻana a me ka lawelawe ʻana i ka 3,5-Difluoropyridine, e hahai mau i nā kaʻina hana palekana lab pono a nānā i nā pepa ʻikepili palekana kūpono a me nā ʻōlelo kuhikuhi.
