Hoʻolauna

2,3-Butanedithiol. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 2,3-butanedithiol:

 

ʻAno maikaʻi:

- Ke ʻano: wai kala ʻole

- ʻAla: ʻAla ʻala

- Hiki ke hoʻoheheʻe ʻia: hiki ke hoʻoheheʻe ʻia i loko o ka wai, nā ʻawaʻawa a me nā solvents ether

 

E hoʻohana:

- Hoʻohana ʻenehana: hiki ke hoʻohana ʻia ʻo 2,3-butanedicaptan ma ke ʻano he mea hoʻokele a me ka antioxidant. Hiki iā ia ke hoʻomaikaʻi i nā waiwai mechanical a me ke kūpaʻa wela o ka lāʻau a hoʻolōʻihi i ke ola lawelawe o nā huahana lāʻau.

 

Hanana:

Hiki ke hana ʻia ka hoʻomākaukau ʻana o 2,3-butanedithiol e kekahi o kēia mau ʻano:

- Hoʻomākaukau ʻenehana: hoʻohana maʻamau ʻia ka butene a me ka sulfur e like me nā mea maka a hoʻomākaukau ʻia e ka hopena vulcanization.

- Ka hoʻomākaukau ʻana o ka Laboratory: Hiki ke hoʻomākaukau ʻia e ka hopena o ka propadiene sulfate a me ka sodium sulfite, a i ʻole ma ka hopena o 2,3-dichlorobutane a me ka sodium sulfide.

 

ʻIke palekana:

- 2,3-butanedithiol he mea hoʻonāukiuki a hiki ke hoʻoulu i ka huhū a me ka wela i nā maka a me kaʻili.

- ʻO ka inhalation o ka nui o 2,3-butanedithiol hiki ke hoʻoulu i ka dizziness, nausea, ka luaʻi a me nā hōʻailona hōʻoluʻolu ʻē aʻe.

- Hōʻalo i ka inhalation a me ka pili ʻana i ka ʻili i ka wā o ka hana, a e hoʻohana i nā mea pale kūpono e like me nā mīkina lima, nā maka aniani, a me nā mea ʻē aʻe ke hoʻohana.

- Hōʻalo i ka hoʻopili ʻana me nā mea oxidants a me nā mea e like me nā ʻakika ikaika a me nā alkalis e pale aku i nā hopena pōʻino.
