Hoʻolauna

(S)-2-(1-Hydroxyethyl)pyridine he hui chiral me ke kumu kemika C7H9NO a loaʻa iā ia nā waiwai ʻike. Loaʻa iā ia ʻelua stereoisomers, ʻo ia ka (S)-2-(1-Hydroxyethyl)pyridine hoʻokahi. He wai waihoʻoluʻu ʻole a melemele me kahi ʻala ʻokoʻa.

 

(S)-2-(1-Hydroxyethyl)pyridine e hoʻohana pinepine ʻia ma ke ʻano he chiral inducer a i ʻole catalyst i ka synthesis organik. Hiki ke hoʻohana ʻia i ka synthesis o nā pūhui stereoisomer ʻē aʻe, nā catalysts no nā hopena synthesis organik, kiʻekiʻe kiʻekiʻe o ka lāʻau synthesis a pēlā aku.

 

Loaʻa ka hoʻomākaukau ʻana o (S)-2-(1-Hydroxyethyl)pyridine ma ka hoʻopili ʻana i ka pyridine me ka acetaldehyde ma lalo o nā kūlana kumu. ʻO ke ʻano hoʻomākaukau kikoʻī paha e hoʻomehana ʻia ka pyridine a me ka acetaldehyde e hana i loko o kahi solution buffer alkaline, a hoʻomaʻemaʻe ʻia ka huahana e ka crystallization e loaʻa (S) -2-(1-Hydroxyethyl) pyridine me ka maʻemaʻe kiʻekiʻe.

 

E pili ana i ka ʻike palekana o (S)-2-(1-Hydroxyethyl)pyridine, he wai ʻaʻa ia a pono e mālama ʻia mai nā lapalapa ākea a me nā wela kiʻekiʻe. E hoʻohana me ka mālama e pale aku i ka inhalation, ka ʻai ʻana a me ka pili ʻana i ka ʻili. E hoʻohana i nā mea pale kūpono e like me nā mīkina lima pale kemika a me nā maka aniani i ka wā e hana ai. E kūʻai ma kahi ʻoluʻolu a me ka ea, a mamao i nā mea ʻona a me nā waikawa ikaika a me nā alkali. Ina accidentally splashed i loko o ka maka a me ka ili, e koke holoi me ka nui o ka wai, a me ka manawa lapaʻau lapaʻau. I ka hoʻohana ʻana a me ka mālama ʻana, e hahai pono i nā kaʻina hana palekana.
