2-Cyano-5-methylpyridine（CAS# 1620-77-5) Hoʻomaka
1. Nānā: colorless i ka wai melemele.
2. Lae hehee:-11 ℃.
3. Puni paila: 207-210 ℃.
4. Solubility: hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me nā ʻawaʻawa a me nā eter.
1. Hoʻohana nui ʻia i ka synthesis organik, hiki ke hoʻohana ʻia e like me ka reagent, intermediate a i ʻole catalyst e komo i nā ʻano like ʻole, e like me ka C- C bond formation reaction, cyanide reaction.
2. Hiki iā ia ke komo i ka synthesis o pyridine, pyridine ketones a me nā mea ʻē aʻe.
3. Hiki ke hoʻohana ʻia i ka pesticide, lāʻau lapaʻau a me nā māla ʻē aʻe.
Hanana:
Hiki ke hoʻomākaukau ʻia e ke ala synthetic penei:
1. Hoʻopili ka Pyridine me ka methyl acetic anhydride e hana i ka 5-methyl pyridine.
2. E hoʻopili i ka 5-picoline me ka sodium cyanide ma lalo o nā kūlana alkaline e hoʻohua ai.
ʻIke palekana:
1. Aia ma luna o nā pūhui organik, aia kekahi mea ʻawaʻawa, e ʻoluʻolu e hahai i nā kaʻina hana palekana lab, e hoʻolohe i nā hana pale.
2. E pale aku i ka pili ana me ka ili, ka maka, a pela aku. Ina he pili, holoi koke me ka wai nui. Inā loaʻa kekahi hewa, e ʻoluʻolu e ʻimi i ka lāʻau lapaʻau.
3. Ma ka mālama ʻana a me ka mālama ʻana, e ʻoluʻolu e pale i ka wela kiʻekiʻe, nā kumu ahi, a mālama i kahi ʻano hana maikaʻi-ventilated.
4. Pono e hoʻolei ʻia ka wai ʻōpala e like me nā kānāwai kūloko e pale aku ai i ka haumia o ke kaiapuni.
E ʻoluʻolu e hahai ka hoʻohana ʻana a me ka lawelawe ʻana i nā mea kemika e pili ana i nā lula kūpono a me nā kaʻina hana palekana, a e hahai i nā alakaʻi hana hoʻokolohua kūpono.
