Hoʻolauna

ʻO ka 4-Iodo-3-nitrobenzoic acid he mea hoʻohuihui kūlohelohe me ke ʻano kemika C7H4INO4. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.

 

ʻAno:

-Nani: 4-Iodo-3-nitrobenzoic acid he pauka crystalline melemele.

-Ka helu hehee: ma kahi o 230°C.

-Solubility: Hiki ke hoʻoheheʻe ʻia i ka ethanol, etera a me ka chloroform, hiki ʻole ke hoʻoheheʻe ʻia i ka wai.

 

E hoʻohana:

- Hoʻohana nui ʻia ka 4-Iodo-3-nitrobenzoic acid ma ke ʻano he waena i ka synthesis organik.

-He mea waiwai nui ia no ka synthesis o nā lāʻau lapaʻau a me nā pesticides.

-Hiki ke hoʻohana ʻia no ka synthesis o nā papa hoʻoheheʻe kukui i nā mea electroluminescent organik (OLED).

 

Kaʻina hoʻomākaukau:

Nui nā ʻano hana no ka hoʻomākaukau ʻana i ka waika 4-Iodo-3-nitrobenzoic, hoʻohana maʻamau ʻia kekahi o ia e loaʻa ma ka nitratation o ka iodobenzoic acid. ʻO nā hana hoʻomākaukau kūikawā penei:

1. hoʻoheheʻe i ka iodobenzoic acid i loko o ka waikawa nitric concentrated.

2. Hoʻohui mālie i ka ʻakika sulfuric concentrated ma ka wela haʻahaʻa a hoʻoulu i ka hopena.

3. Ma hope o ka hoʻokō ʻia ʻana o ka hopena no kekahi manawa, ua hoʻokaʻawale ʻia ka huahana i loko o ka hopena hopena e ka kānana a i ʻole crystallization.

4. Ua hoʻomaʻemaʻe hope ʻia ka 4-Iodo-3-nitrobenzoic acid ma ka holoi ʻana me ka solvent a me ka crystallization kūpono.

 

ʻIke palekana:

- ʻO ka 4-Iodo-3-nitrobenzoic acid kahi mea hoʻohuihui. Pono e mālama ʻia nā hana pale pilikino i ka wā e hoʻohana ai, e like me ke komo ʻana i nā mīkina lima a me nā makaaniani pale maka.

-He mea ʻino ka hui i kekahi ʻano, e pale i ka pili ʻana i ka ʻili a me ka inhalation.

-I ka wā o ka hana, e hoʻolohe i ka hoʻopili ʻana me nā oxidants ikaika a me nā mea hoʻohaʻahaʻa e pale aku i nā hopena weliweli.

- I ka wā e mālama ai, pono e mālama ʻia ma kahi ʻoluʻolu, maloʻo, maikaʻi-ventilated, hoʻokaʻawale ʻia mai nā mea wela a me nā mea puhi.

-Inā pili, holoi koke i ka wahi i hoʻopilikia ʻia me ka wai nui a ʻimi i ke kōkua olakino.
