Hoʻolauna
ʻO ka 3-Nitro-5-bromobenzoic acid (3-Bromo-5-nitrobenzoic acid) he mea hoʻohuihui me ke ʻano kemika C7H4BrNO4. Eia ka wehewehe ʻana o nā waiwai, hoʻohana, hoʻomākaukau a me ka ʻike palekana o ka pūhui:
ʻAno:
-Nani: 3-Nitro-5-bromobenzoic acid he māmā melemele māmā.
-Ka helu hehee: ma kahi o 220-225°C.
-Solubility: Haʻahaʻa haʻahaʻa i ka wai, akā hiki ke hoʻoheheʻe ʻia e like me ka ethanol, chloroform a me dichloromethane.
-ʻakika a me ka alkaline: he ʻakika nāwaliwali.
E hoʻohana:
-3-nitro-5-bromobenzoic acid ua hoʻohana pinepine ʻia ma ke ʻano he waena i ka synthesis organik a hoʻohana ʻia i ka hoʻomākaukau ʻana i nā pūhui ʻē aʻe.
-Hiki ke hoʻohana ʻia e hoʻomākaukau i nā pūhui e like me nā lāʻau lapaʻau, nā kala a me nā uhi.
Kaʻina hoʻomākaukau:
ʻO ka hoʻomākaukau ʻana i ka 3-nitro-5-bromobenzoic acid hiki ke hoʻopau ʻia e nā pae aʻe:
1. Ua loaʻa ka 3-nitrobenzoic acid ma ka hopena o ka waikawa benzoic a me ka waikawa nitrous.
2. Ma ke alo o ka ferrous bromide, 3-nitrobenzoic acid e hoʻopili ʻia me ka sodium bromide e loaʻa ai ka 3-nitro-5-bromobenzoic acid.
ʻIke palekana:
ʻO ka 3-Nitro-5-bromobenzoic acid ka mea maʻamau i ka palekana i ka hoʻohana pono a me ka mālama ʻana. Eia nō naʻe, pono e hoʻomaopopo ʻia nā mea i lalo:
-E pale i ka pili ʻana i ka ʻili, ka inhalation a me ka ʻai ʻana i ka wā o ka hana.
-E hoʻohana i nā mea pale kūpono e like me nā mīkina lima, nā aniani, a me nā pale maka ke hoʻohana ʻia.
-Inā pili ʻoe i ka hui, holoi koke me ka wai nui a ʻimi i ka lāʻau lapaʻau.
-pono e mālama ʻia mai ke ahi a me ka oxidant, ma kahi maloʻo a maloʻo.
'Ōlelo Aʻo: ʻO ka ʻike ma luna no ka ʻike wale nō. E ʻoluʻolu e hahai i nā lula palekana i ka wā e hana ai i ka hale hana, a e nīnau i ka pepa ʻikepili palekana o ka pūhui kikoʻī inā pono.
