Hoʻolauna

ʻO 5-Hydroxy-4-octanone kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:

 

ʻAno maikaʻi:

ʻAno: 5-hydroxy-4-octanone he wai kala ʻole.

Māmā: ma kahi o 0.95 g/cm3.

Solubility: 5-hydroxy-4-octanone ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai a loaʻa ka solubility maikaʻi i nā mea hoʻoheheʻe organik.

 

E hoʻohana:

Hiki ke hoʻohana ʻia ʻo 5-Hydroxy-4-octanone ma ke ʻano he mea hoʻoulu kila kila me ka hiki ke hoʻoneʻe i ka ʻōpala a me ka maʻemaʻe o ka metala.

ʻO ia hoʻi kahi mea hoʻoheheʻe fluorescent e hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā kala fluorescent o nā waihoʻoluʻu like ʻole.

 

Hanana:

Hoʻomākaukau ʻia ʻo 5-Hydroxy-4-octanone e ka synthesis kemika. ʻO ke ʻano hoʻomākaukau maʻamau, ʻo ia ka hoʻoheheʻe ʻana i ka octanone i loko o kahi mea hoʻoheheʻe, a laila hoʻohui i kahi nui kūpono o ka oxidant a me ka hopena hopena, a hoʻokō i ka hopena ma lalo o nā kūlana kūpono e loaʻa ai ka huahana.

 

ʻIke palekana:

Palekana maʻamau ka 5-Hydroxy-4-octanone ma lalo o nā kūlana hoʻohana maʻamau a ʻaʻohe ona mea make.

Loaʻa iā ia kahi volatility a pono e hoʻohana ʻia i kahi wahi i hoʻoluʻu maikaʻi ʻia.

I ka wā o ka hoʻohana ʻana, pono e pale ʻia ka pili ʻana me ka ʻili a me nā maka, a inā loaʻa ka pili, holoi koke me ka wai nui.

I ka wā o ka lawe ʻana a mālama ʻana paha, e pale i ka hoʻopili ʻana me nā mea oxidizing ikaika e like me nā oxidants a me nā ʻakika e pale ai i nā hopena pōʻino.

I ka wā o ka mālama ʻana, pono e mālama ʻia ka 5-hydroxy-4-octanone i loko o kahi pahu hau, ma kahi mamao o ke ahi a me nā wela kiʻekiʻe.
