Hoʻolauna

ʻO ka γ-crotonyllactone (GBL) kahi mea hui. ʻO kēia ka hoʻolauna ʻana i ke ʻano, hoʻohana, hana hana a me ka ʻike palekana o GBL:

 

ʻAno maikaʻi:

ʻAno: ʻO ka wai aniani ʻaʻohe waihoʻoluʻu me ka ʻala like me ka ethanol.

Māmā: 1.125 g/cm³

Solubility: Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik, e like me ka wai, ka waiʻona, ether, etc.

 

E hoʻohana:

Hoʻohana ʻenehana: Hoʻohana nui ʻia ʻo GBL ma ke ʻano he surfactant, dye solvent, resin solvent, plastic solvent, clean agent, etc.

 

Hanana:

Hiki ke loaʻa ka GBL ma o ka oxidizing crotonone (1,4-butanol). ʻO ke ʻano o ka hoʻomākaukau ʻana, ʻo ia ka hana ʻana i ka crotonone me ke kinoea chlorine e hoʻohua i ka 1,4-butanedione, a laila hydrogenate 1,4-butanedione me NaOH e hoʻohua i ka GBL.

 

ʻIke palekana:

Loaʻa i ka GBL nā hiʻohiʻona o ka volatility kiʻekiʻe a me ka maʻalahi o ka lawe ʻana i ka ʻili a me ka mucous membranes, a loaʻa kekahi mea ʻona i ke kino kanaka. E hoʻohana me ka akahele.

Hiki i ka GBL ke loaʻa i ka hopena i ka ʻōnaehana nūnū waena, a ʻo ka hoʻonui ʻia ʻana e hiki ke alakaʻi i nā hopena ʻino e like me ka noʻonoʻo, ka hiamoe, a me ka nāwaliwali o ka ʻiʻo. E mālama i nā kānāwai a me nā hoʻoponopono kūpono.
