Hoʻolauna

ʻO Ethyl maltol kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka ethyl maltol:

 

ʻAno maikaʻi:

ʻO ka Ethyl maltol kahi wai ʻole a ʻeleʻele melemele me kahi ʻala kūikawā. He mea maʻalahi ma ka lumi wela, hiki ke hoʻoheheʻe ʻia i loko o nā waiʻona a me nā mea hoʻoheheʻe momona, a hiki ʻole ke hoʻoheheʻe ʻia i ka wai. He kūpaʻa maikaʻi loa ʻo Ethyl maltol a hiki ke noho paʻa no ka manawa lōʻihi ma lalo o ka mana o ka oxygen a me ka lā.

 

E hoʻohana:

 

Hanana:

Nui nā ala e hoʻomākaukau ai i ka ethyl maltol, a ʻo ke ʻano hana maʻamau ʻo ia ka esterify maltol me ka ethanol i mua o kahi catalyst e loaʻa ai ka ethyl maltol. Pono e nānā i ka mālama ʻana i nā kūlana hopena a me ke koho ʻana i ka catalyst i ka wā o ka hoʻomākaukau ʻana e hōʻoia i ka maʻemaʻe o ka huahana a me ka hopena hopena.

 

ʻIke palekana:

E pale i ka pili ʻana me nā maka a me ka ʻili i ka wā e hoʻohana ai, a holoi koke me ka wai nui inā pili.

E pale i ka inhalation lōʻihi a me ka ʻai ʻana i mea e pale ai i ka hoʻonāukiuki ʻana i nā ʻōnaehana hanu a me ka ʻai.

I ka mālama ʻana, e pale i ka hoʻopili ʻana me nā mea hoʻomake ikaika a mālama i kahi maloʻo a maloʻo maikaʻi.

I ka hihia o ka ʻai ʻana a i ʻole ka hōʻoluʻolu, e ʻimi i ka lāʻau lapaʻau a haʻi i kāu kauka i nā mea kemika i hoʻohana ʻia.
