Hoʻolauna

(R)-2-(1-hydroxyethyl)pyridine he hui kemika.

 

ʻAno maikaʻi:

(R)-2-(1-hydroxyethyl)pyridine he wai kala ʻole i ka wai melemele māmā. He ʻala ʻala a me nā waiwai alkaline. Hiki ke hoʻoheheʻe ʻia ka mea hoʻohui i ka wai, nā waiʻona, a me nā solvents ether.

 

E hoʻohana:

(R)-2-(1-hydroxyethyl)pyridine he mea koʻikoʻi i waena o ka synthesis organik, i hoʻohana maʻamau ʻia ma ke ʻano he catalyst, ligand a i ʻole mea hoʻohaʻahaʻa i nā hopena synthesis organik.

 

Hanana:

ʻO ke ʻano hoʻomākaukau o (R)-2-(1-hydroxyethyl)pyridine ka mea maʻamau e hoʻokō ʻia e ka synthesis kemika. ʻO kahi hana maʻamau e hoʻohui i kahi hui hydroxyethyl i ka mole pyridine e hana i ka stereoconfiguration ma ka lima ʻākau me kahi catalyst a me nā kūlana kūpono. Hiki ke hoʻonui a hoʻomaikaʻi ʻia ke ʻano hana synthesis e like me nā pono maoli.

 

ʻIke palekana:

He kiʻekiʻe ka ʻike palekana o (R)-2-(1-hydroxyethyl)pyridine, akā pono e mālama pono ʻia nā mālama pilikino i ka wā o ka lawelawe ʻana. Inā pili me ka ʻili a me nā maka, holoi koke me ka wai nui. E hōʻalo i ka hoʻohu ʻana i kāna mau kinoea a i ʻole nā ​​​​huhū a koho i nā kūlana ea kūpono. I ka wā o ka hoʻohana ʻana, e pale aku i ka hoʻopili ʻana me nā mea hoʻoheheʻe ikaika a me nā mea hiki ke ahi e pale aku i ka pōʻino. Pono nā hana palekana kūikawā e hahai i nā manual palekana kūpono a i ʻole nā ​​alakaʻi ʻenehana no nā kemika.
