4-Iodo-3-nitrobenzoic acid(CAS# 35674-27-2)
Nā Code Risk | R20/21/22 – He pōʻino ma ka inhalation, pili me ka ʻili a inā ale ʻia. R36/37/38 – Hoʻonanea i ka maka, ka ʻōpū hanu a me ka ʻili. |
Ka wehewehe palekana | S22 – Mai hanu i ka lepo. S26 – Inā pili me nā maka, e holoi koke me ka wai nui a e ʻimi i ka ʻōlelo aʻo kino. S36/37/39 – E hoʻohana i nā lole pale kūpono, nā mīkina lima a me ka pale maka/maka. |
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.
