Hoʻolauna
ʻO ka 3-choro-5-(trifluoromethyl)pyridine he mea hoʻohuihui me ke ʻano kemika C≡H₂ ClFΛ N. He wai waihoʻoluʻu ʻole a ʻeleʻele melemele me ka ʻala. Eia ka wehewehe ʻana o ke ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana o 3-choro-5-(trifluoromethyl)pyridine:
ʻAno:
-Ka mānoanoa: 1.578 g/mL
-Pila paila: 79-82 ℃
-Ka helu hehee:-52.5 ℃
-Solubility: Hiki ke hoʻoheheʻe ʻia e like me ka ethanol, ether a me dichloromethane, hiki ke hoʻoheheʻe iki i ka wai.
E hoʻohana:
-E like me nā reagents a me nā intermediates i ka synthesis organik, hoʻohana ʻia i ka synthesis o nā pesticides, nā lāʻau lapaʻau a me nā mea hoʻohui ʻē aʻe.
-No ka noiʻi ʻana i ka lāʻau lapaʻau, e like me ka synthesis o nā lāʻau anti-cancer a me nā biomarkers.
Kaʻina hoʻomākaukau:
Hiki ke hoʻomākaukau ʻia ka 3-chloro-5-(trifluoromethyl)pyridine e nā ʻano ʻelua:
1. Ke hoʻohana nei i ka pyridine ma ke ʻano he mea maka, lawe ʻia ka hopena chlorination i mua o ka waika hydrochloric, a laila lawe ʻia ka hopena trifluoromethylation i mua o ka sodium trifluoromethylate.
2. Ke hoʻohana nei i ka 3-picolinic acid ma ke ʻano he mea maka, e hana ʻia kahi hopena chlorination i mua o ka thionyl chloride, a laila lawe ʻia kahi hopena trifluoromethylation i mua o ka trifluoromethyl mercaptan.
ʻIke palekana:
- ʻO 3-chloro-5-(trifluoromethyl)pyridine he mea hoʻonāukiuki a hiki ke hoʻoulu i ka hoʻopili ʻana me ka ʻili a me nā maka. Pono e hoʻokomo i nā mea pale kūpono i ka wā e hoʻohana ai, e like me ke komo ʻana i nā aniani pale, nā mīkina lima a me nā lole pale.
-E hōʻalo i ka hoʻohu ʻana i kona mahu a hōʻoia i ka hana ʻia ʻana o ka hana ma kahi maikaʻi-ventilated.
-I ka wā e mālama ai, e mālama i loko o kahi pahu i hoʻopaʻa ʻia, ma kahi mamao o ke ahi a me nā mea hoʻoheheʻe.
-I ka wā e hoʻolei ai i ka ʻōpala, mālama a hoʻolei ʻia e like me nā kānāwai kūloko.
-E ʻoluʻolu e nānā i ka Pepa ʻIkepili Palekana (SDS) pili no ka ʻike palekana.
