Hoʻolauna
2,3-Dichlorobenzoyl chloride. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:
ʻAno maikaʻi:
- Ke ʻano: 2,3-Dichlorobenzoyl chloride he kala ʻole i ka wai melemele māmā.
- Solubility: 2,3-Dichlorobenzoyl chloride hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me nā ethers a me nā ʻona, akā hiki ʻole ke hoʻoheheʻe ʻia i ka wai.
E hoʻohana:
- 2,3-Dichlorobenzoyl chloride he mea koʻikoʻi waena waena a hoʻohana pinepine ʻia i nā hopena synthesis organik.
- Hiki ke hoʻohana ʻia ka 2,3-Dichlorobenzoyl chloride ma ke ʻano he acylation reagent no ka hoʻohuli ʻana i nā hui hydroxyl i nā hui acyl.
- Hoʻohana ʻia ia i ka hoʻomākaukau ʻana i nā mea kōkua hoʻoheheʻe a me nā mea polymer, ma waena o nā māla ʻē aʻe.
Hanana:
- Hiki ke loaʻa ka 2,3-Dichlorobenzoyl chloride ma ka hana ʻana i ka 2,3-dichlorobenzoic acid me ka thionyl chloride. Hoʻomaʻamaʻa ʻia nā ʻano hopena i loko o kahi lewa inert a hiki i ka hoʻoheheʻe ʻana o nā mea hoʻoheheʻe, a hoʻohui mālie ʻia ka thionyl chloride.
- Penei ka hoohalike pane:
C6H4(Cl)COOH + SO2Cl2 → C6H4(Cl)C(O)Cl + H2SO4
ʻIke palekana:
- ʻO 2,3-Dichlorobenzoyl chloride kahi hui kūlohelohe me kekahi mea ʻona. Hiki i ka ʻike ʻana a i ʻole ka inhalation o ka hui ke hoʻonāukiuki a hōʻino i ka ʻili, nā maka, a me ka ʻōpū hanu.
- I ka hoʻohana ʻana i ka 2,3-dichlorobenzoyl chloride, pono e hoʻomaʻamaʻa maikaʻi ʻia ka ventila maikaʻi a pono e hoʻohana ʻia nā lako pale pilikino kūpono e like me nā mīkina lima, nā aniani palekana, a me nā maka pale.
- I ka wā o ka mālama ʻana a me ka mālama ʻana, pono e mālama pono ʻia nā kaʻina hana palekana kemika, a mālama ʻia nā kumu ahi a me nā mea hiki ke puhi ʻia.
- Inā ale ʻia ka 2,3-dichlorobenzoyl chloride ma ke kuhi hewa ʻole, e ʻimi koke i ka lāʻau lapaʻau a lawe mai i ka ʻike e pili ana i ka pūhui.
