Hoʻolauna
ʻO ka 4-Bromo-2-nitrobenzoic acid he mea hoʻohuihui, i hoʻopau pinepine ʻia ʻo BNBA. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:
ʻAno maikaʻi:
- Ke ʻano: 4-Bromo-2-nitrobenzoic acid he paʻa keʻokeʻo keʻokeʻo.
- Solubility: Hiki ke hoʻoheheʻe maikaʻi ʻia i nā mea hoʻoheheʻe kūlohelohe maʻamau e like me ka ethanol, chloroform a me dimethylformamide.
E hoʻohana:
- Māhele Pigment: Hiki ke hoʻohana ʻia kēia pūhui e hoʻomākaukau i kekahi mau puaʻa kūikawā.
Hanana:
- Loaʻa maʻamau ka hoʻomākaukau ʻana i ka waikawa 4-bromo-2-nitrobenzoic ma ka hana ʻana i ka 2-nitrobenzoic acid a me ka bromine ma lalo o nā kūlana acidic. No ke ʻano hoʻomākaukau kikoʻī, e ʻoluʻolu e ʻike i ka palapala hoʻohui organik pili.
ʻIke palekana:
- Loaʻa i ka pūhui kekahi mea hoʻonāukiuki, a pono e lawe ʻia nā mea pale e like me ke komo ʻana i nā mīkina lima, nā maka aniani, a me nā mea ʻē aʻe.
- E mālama i nā lapalapa a me nā mea wela kiʻekiʻe, a mālama i kahi maloʻo maloʻo.
- ʻAʻole lawa ka ʻikepili ʻona, ʻaʻole ʻike ʻia ka toxicity o 4-bromo-2-nitrobenzoic acid, a pono e mālama pono i ka wā e hoʻohana ai a mālama ʻia paha, a pono e hahai ʻia nā hana hana palekana kūpono.
