2-Chloro-5-fluorobenzaldehyde（CAS# 84194-30-9)
Pilikia a palekana
| Nā Code Risk | R22 – Poino ke aleia R37/38 – Hoʻonanea i ka ʻōnaehana hanu a me ka ʻili. R41 – Ka pilikia o ka poino nui i na maka |
| Ka wehewehe palekana | S26 – Inā pili me nā maka, e holoi koke me ka wai nui a e ʻimi i ka ʻōlelo aʻo kino. S39 - Hoʻohana i ka pale maka / maka. |
| Papa Hazard | HOOLAHA |
Hoʻolauna
-Nani: Ke aniani keʻokeʻo a i ʻole ka paʻa melemele māmā.
-Ka helu heheʻe: ma kahi o 40-42 ℃.
-Pila paila: ma kahi o 163-165 ℃.
-Density: ma kahi o 1.435g/cm³.
-Solubility: Hiki ke hoʻoheheʻe ʻia i kekahi mau mea hoʻoheheʻe kūlohelohe maʻamau, e like me ka ethanol, chloroform a me dichloromethane.
E hoʻohana:
Hoʻohana nui ʻia ia no nā hopena kemika i ka synthesis organik. Hiki ke hoʻohana ʻia ma ke ʻano he waena o nā mea hoʻonaninani fluorescent, ma ke ʻano he mea maka i ka lāʻau lapaʻau, a ma ka māla mahiʻai no ka hoʻomākaukau ʻana i nā pesticides.
Kaʻina hoʻomākaukau:
Hiki ke hoʻomākaukau ʻia e ka chlorination, fluorinated benzaldehyde method. ʻO ke ʻano hoʻomākaukau kūikawā penei:
1. Ma lalo o nā kūlana kūpono, hoʻohui ʻia ka waika hydrofluoric i benzaldehyde e ʻae iā ia e hana i kahi hopena fluorination.
2. Ma hope o ka hopena, hoʻohui ʻia ka hydrogen chloride e chlorinate i ka huahana fluorinated.
3. e hoʻokō i nā hana hoʻomaʻemaʻe kūpono e loaʻa ai ka phosphonium maʻemaʻe.
ʻIke palekana:
-ʻo ia nā mea ʻino, hiki ke hoʻonāukiuki i ke kino o ke kanaka. E hoʻohana i nā mīkina lima pale, nā makaaniani a me nā mea pale hanu inā pono.
-E hōʻalo i ka hanu ʻana i ka lepo a i ʻole ke kinoea, a pale i ka pili ʻana me ka ʻili a me nā maka.
- I ka mālama ʻana a me ka hoʻohana ʻana, pono e mālama ʻia nā kaʻina hana palekana kemika, a pono e mālama ʻia nā kūlana ventila kūpono.
-No ka ʻike ʻole ʻana a i ʻole ka ʻai ʻana, e ʻimi koke i ka lāʻau lapaʻau a hāʻawi i ka ʻikepili palekana kūpono.
