Hoʻolauna

ʻO ka Ethyl (R)-(-)-3-hydroxybutyrate, i ʻike ʻia ʻo (R)-(-)-3-hydroxybutyric acid ethyl ester, he mea hoʻohuihui. Penei kona mau waiwai.

 

ʻAno maikaʻi:

- Ke ʻano: wai kala ʻole

 

E hoʻohana:

ʻO Ethyl (R)-(-)-3-hydroxybutyrate ka laulā o nā noi ma ke kahua o ke kemika:

- Hiki iā ia ke hana i kahi hana koʻikoʻi ma ke ʻano he catalyst i nā hopena synthesis organik.

 

Hanana:

Nui nā ala e hoʻomākaukau ai i ka ethyl (R)-(-)-3-hydroxybutyrate:

- ʻO ke ala maʻamau ka hoʻomākaukau ʻana ma o ka esterification o ka waika hydroxybutyric, ka mea e hoʻopili i ka waika hydroxybutyric me ka ethanol, e hoʻohui i kahi catalyst acid e like me ka sulfuric acid a i ʻole formic acid, a distills i ka huahana maʻemaʻe ma hope o ka hopena.

- Hiki ke hoʻomākaukau ʻia ma ka hoʻohui ʻana i ka waika succinic me ka ethanol, ka hoʻohui ʻana i nā catalysts acid, a laila hydrolysis.

 

ʻIke palekana:

He palekana ka Ethyl (R)-(-)-3-hydroxybutyrate no ka hoʻohana maʻamau, akā pono e hoʻomaopopo ʻia kēia mau mea:

- He wai wela ia a pono e pale ʻia mai ka hoʻopili ʻana me nā lapalapa ākea a me nā wela kiʻekiʻe.

- Pono e mālama pono i ka palekana, e like me ke komo ʻana i nā aniani pale a me nā mīkina lima, i ka wā o ka hana.

- Hōʻalo i ka inhalation, ingestion, a me ka pili ʻana i ka ʻili i ka ʻili e pale aku i ka ʻeha a me ka ʻeha.

- Inā pili, holoi koke i ka wahi i hoʻopilikia ʻia me ka wai nui a ʻimi i ka lāʻau lapaʻau.
