Hoʻolauna

4-Hydroxy-5-methyl-3(2H)-furanone. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, hana hana a me ka ʻike palekana:

 

ʻAno maikaʻi:

- Ke ʻano: 4-Hydroxy-5-methyl-3(2H) -furanone he wai kala ʻole a maopopo.

- Solubility: Hiki ke hoʻoheheʻe ʻia i ka wai a i ʻole nā ​​​​mea hoʻoheheʻe organik.

 

E hoʻohana:

- Hiki ke hoʻohana ʻia ka 4-Hydroxy-5-methyl-3(2H) -furanone ma ke ʻano he waena i ka synthesis organik no ka hoʻomākaukau ʻana i nā mea hoʻohui ʻē aʻe.

 

Hanana:

- Hiki ke hoʻomākaukau ʻia ka 4-Hydroxy-5-methyl-3(2H) -furanone e ka methylalkane oxidation a me ka brominated hydroxylation.

 

ʻIke palekana:

- ʻAʻole i hoʻokumu ʻia ka pae ʻawaʻawa o 4-hydroxy-5-methyl-3(2H)-furanone a pono e hoʻohana ʻia me ka mālama pono a e like me nā protocol mālama palekana o nā kemika pili.

- E hōʻalo i ka pili ʻana me ka ʻili, nā maka, a me nā ʻili mucous ʻē aʻe i ka wā e hoʻohana ai, a e hana i nā mea pale e like me ke komo ʻana i nā aniani palekana a me nā mīkina lima.

- No ka mālama ʻana, pono e mālama ʻia ka 4-hydroxy-5-methyl-3(2H)-furanone ma kahi maloʻo maloʻo ma kahi mamao mai ke ahi a me nā oxidants.
