Hoʻolauna
ʻO ka 2-Chloro-3-methoxypyridine(2-Chloro-3-methoxypyridine) he hui lāʻau me ke ʻano kemika C6H6ClNO. He wai waihoʻoluʻu me ka ʻala ʻala. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.
ʻAno:
-Nani: wai kala ʻole
-Molecular kaumaha: 159.57g/mol
-Lae hehee: ʻAʻole ʻike ʻia
-Pila paila: 203-205 ℃
-Ka mānoanoa: 1.233g/cm3
-Solubility: Hiki ke hoʻoheheʻe ʻia i ka ethanol, ether a me nā hydrocarbons chlorinated
E hoʻohana:
- Hoʻohana mau ʻia ʻo 2-Chloro-3-methoxypyridine ma ke ʻano he mea waena i nā hopena synthesis organik.
-Ma ke kahua o ka lāʻau lapaʻau, hiki ke hoʻohana ʻia e synthesize i nā intermediates pharmaceutical a me nā lāʻau ikaika.
Kaʻina hoʻomākaukau:
ʻO ke ʻano o ka hoʻomākaukau ʻana o 2-Chloro-3-methoxypyridine i loaʻa nui ʻia e ka protonation a me ka hopena chlorination o pyridine. Hiki i nā ala synthetic kikoʻī ke:
1. ka hoʻopili ʻana i ka pyridine me ka hydrogen chloride e loaʻa ai ka chloropyridine;
2. Hoʻohuiʻia ka methanol a me ka sodium hydroxide i ka solution chloropyridine e hana i kahi huahana, i hoʻomaʻemaʻeʻia no ka loaʻaʻana o 2-Chloro-3-methoxypyridine.
ʻIke palekana:
- ʻO 2-Chloro-3-methoxypyridine kahi mea hoʻohuihui a hoʻonāukiuki. Pono e pale aku i ka pili pono me ka ʻili a me nā maka.
-I ka wā o ka mālama ʻana a i ʻole ka mālama ʻana, pono e lawe ʻia nā hana palekana kūpono a pono e hoʻohana ʻia nā mea pale pilikino e like me nā mīkina lima a me nā maka.
-E hōʻalo i ka hanu ʻana i kāna mahu a i ʻole ka hopena i ka wā o ka hoʻohana ʻana a mālama pono i ka makani.
- Hōʻalo i ka hoʻopili ʻana me nā oxidants ikaika, nā ʻakika ikaika a me nā mea ʻē aʻe e pale ai i nā hopena ʻino.
-Ma hope o ka hoʻohana ʻana a i ʻole ka hoʻokuʻu ʻia ʻana, pono e hoʻolei ʻia nā koena kemika me ka palekana a me ka hoʻokō ʻana i nā lula palekana pili kaiapuni.
