Hoʻolauna

ʻO 4-4-Hydroxy-3-methoxybutyl-2-one, i ʻike ʻia ʻo 4-hydroxy-3-methoxypentanone, he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kekahi o kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana.

 

ʻAno maikaʻi:

- Ke ʻano: ʻAʻole waihoʻoluʻu a i ʻole ka wai melemele māmā a paʻa paha.

- Solubility: Hiki ke hoʻoheheʻe ʻia e like me ka ethanol a me ka dimethylformamide, hiki ʻole ke hoʻoheheʻe ʻia i ka wai.

- ʻAiʻona: He mea ʻawaʻawa ka pūhui a koi aku i nā hana palekana e pono ai ke hoʻohu ʻia a i ʻole ka pili ʻana me ka ʻili.

 

E hoʻohana:

- Nā hoʻokolohua kemika: Hiki ke hoʻohana ʻia ma ke ʻano he reagent no kekahi mau hoʻokolohua kemika.

 

Hanana:

Hiki ke hoʻokō ʻia ke ʻano hoʻomākaukau o 4-4-hydroxy-3-methoxybutyl-2-one e ka synthesis organik ma lalo o nā kūlana kūpono. Nui paha nā ʻano e hoʻomākaukau ai, akā eia kekahi o nā ala hiki.

E hoʻoheheʻe i ka nui kūpono o ka pentanone i loko o kahi mea hoʻoheheʻe organik.

E hoʻonui i ka waiʻona sodium hydroxide.

Ma kahi mahana a me ke kaomi mau, hoʻohui mālie ʻia ka methanol i loko o ka hui ʻana.

Me ka hoʻohui ʻana o ka methanol, ua hoʻokumu ʻia ka 4-4-hydroxy-3-methoxybutyl-2-one i ka hui ʻana.

Hoʻomaʻemaʻe houʻia ka huahana no ka loaʻaʻana o ka hui hope loa.

 

ʻIke palekana:

- He mea ʻawaʻawa kēia mea hoʻohui a pono e pale ʻia e ka inhalation a i ʻole ka pili ʻana i ka ʻili.

- Pono e mālama ʻia nā hana palekana kūpono i ka wā e hoʻohana ai, e like me ke komo ʻana i nā maka aniani kemika, ke komo ʻana i nā mīkina lima kemika a me nā lole pale.

- Hoʻopau ʻōpala: Ua hui ʻia ka ʻōpala me nā mea hoʻoheheʻe kūpono a hoʻolei ʻia e kahi hale hoʻolei ʻōpala kūpono e like me nā lula kūloko.
