Hoʻolauna

(5h) ʻo furanone he mea hoʻohuihui mea ola me ke ʻano kemika C8H12O3 a me ke kaumaha molekala o 156.18g/mol. He wai waihoʻoluʻu ʻole a ʻeleʻele melemele me ka ʻono koʻikoʻi. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.

 

ʻAno:

-Nani: ʻAʻohe kala i ka wai melemele māmā

-Ka helu heheʻe:-7 ℃

-Pila paila: 171-173 ℃

-Density: approx. 1.079g/cm³

-Solubility: Hiki ke hoʻoheheʻe ʻia i ka wai, ethanol a me nā mea hoʻoheheʻe Etera

-Stability: paʻa paʻa i ka wela lumi

 

E hoʻohana:

-Hoʻohui meaʻai: Ma muli o kona ʻono kūikawā, hoʻohana ʻia ia ma ke ʻano he mea ʻono meaʻai, ʻoi aku hoʻi i ka candy, jam a me ka ʻono.

-Nā ʻala: Hiki ke hoʻohana ʻia i mea ʻala e hāʻawi i ka meaʻai i kahi ʻono kūʻokoʻa.

-ʻoihana ʻala: ʻo ia kekahi o nā mea hoʻohui o ka mea ʻala.

 

Hanana:

(5h) hiki ke hoʻomākaukau ʻia ka furanone e nā ʻanuʻu aʻe:

1. Me ka 3-methyl -2-pentanone e like me ka mea hoʻomaka, 3-hydroxy -4-methyl -2-pentanone i loaʻa ma ke keto-alcohol reaction.

Hoʻopili ʻia ka 2.3-hydroxy -4-methyl -2-pentanone me kahi mea etherifying agent (e like me diethyl ether) e hana i kahi huahana etherification.

3. Hoʻokomo ʻia ka huahana etherification i ka catalysis acid a me ka hopena deoxidation e loaʻa ai ka furanone (5h).

 

ʻIke palekana:

-(5h) ua manaʻo ʻia ka furanone he palekana no ka hoʻohana maʻamau, akā hiki ke hoʻonāukiuki i ka ʻili a me nā maka i nā kiʻekiʻe kiʻekiʻe.

- Pono e hoʻohana i ka nānā ʻana i nā hana pale, e pale i ka pili ʻana me ka ʻili a me nā maka, a mālama i kahi wahi hana maikaʻi.

-E hahai i nā kaʻina hana palekana i ka wā e hoʻohana ai, a mālama iā ia ma kahi maloʻo a maʻalili, mamao mai ke ahi a me nā mea hoʻoheheʻe.
