Hoʻolauna
ʻO ka 1,1-dibromo-3,3,3-trifluoroacetone kahi mea hoʻohuihui me ke ʻano kemika C3Br2F3O. Eia ka wehewehe ʻana o nā waiwai, hoʻohana, hoʻomākaukau a me ka ʻike palekana o ka pūhui:
ʻAno:
-Nani: 1,1-dibromo-3,3,3-trifluoroacetone he kala ʻole i ka wai melemele māmā a i ʻole crystalline solid.
-Ka mānoanoa: 1.98g/cm³
-kahi hoʻoheheʻe: 44-45 ℃
-Pila paila: 96-98 ℃
-Solubility: Hiki ke hoʻoheheʻe ʻia i ka wai, ethanol a me ka etera.
E hoʻohana:
- Hoʻohana nui ʻia ka 1,1-dibromo-3,3,3-trifluoroacetone ma ke ʻano he reagent synthesis organik a hiki ke hoʻohana ʻia e hoʻomākaukau i nā pūhui ʻē aʻe.
- Hiki ke hoʻohana ʻia ka pūhui ma ke ʻano he catalyst, surfactant, a ma nā noi keʻena no ka hoʻoholo ʻana i nā mika microwave.
Kaʻina hoʻomākaukau:
Hiki ke hoʻomākaukau ʻia ka 1,1-dibromo-3,3,3-trifluoroacetone e nā ʻanuʻu aʻe:
1. ʻO ka mea mua, hana ka acetone me ka bromine trifluoride e hoʻohua i ka 3,3, 3-trifluoroacetone.
2. A laila, ma lalo o nā kūlana kūpono, 3,3,3-trifluoroacetone e hoʻopili ʻia me ka bromine e hoʻohua i ka 1,1-dibromo-3,3,3-trifluoroacetone.
ʻIke palekana:
ʻO 1,1-dibromo-3,3,3-trifluoroacetone kahi hui bromine organik me kekahi mea ʻawaʻawa a me ka corrosiveness. E noʻonoʻo i nā mea palekana i ka wā e hoʻohana ai:
-E hōʻalo i ka hoʻopili pololei ʻana me ka ʻili a me nā maka, e hoʻokomo i nā mīkina lima pale, nā maka pale a me ka pale maka pale inā pono.
-E hana i loko o ka ea ea e pale aku i ka inhalation o nā kinoea a me nā mahu.
-E hōʻalo i ka hoʻopili ʻana me nā oxidants a me nā mea puhi ahi i ka wā o ka mālama ʻana, a waiho iā lākou i loko o kahi pahu paʻa, kahi mamao aku i nā kumu ahi a me nā wahi wela kiʻekiʻe.
- Hōʻalo i nā huna ahi a me ka uila paʻa i ka wā e hoʻohana ai e pale i ke ahi a pahū paha.
E ʻoluʻolu e hoʻomaopopo ʻo 1,1-dibromo-3,3,3-trifluoroacetone he mea hoʻolaʻa ʻoihana ʻoihana, hiki ke hoʻohana wale ʻia e nā poʻe loea ma lalo o nā kūlana kūpono a ʻaʻole pono e hoʻohana a lawelawe ʻia ma ka makemake.
