Hoʻolauna

ʻO 2-Methylthioethanol, ka mea i ʻike ʻia ʻo 2-methylthioethanol, he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:

 

ʻAno maikaʻi:

- Ke ʻano: 2-Methylthioethanol he wai kala ʻole i ka wai melemele māmā.

- ʻAla: He ʻala ikaika o ka hydrogen sulfide.

- Solubility: Hiki ke hoʻoheheʻe ʻia i loko o ka wai a me kekahi mau mea hoʻoheheʻe kūlohelohe e like me nā ʻona a me nā eter.

- Nā waiwai: He mea maʻalahi ia i ka ea a hiki ke hoʻoneʻe ʻia i ka disulfide, kahi maʻalahi e hoʻopau ai.

 

E hoʻohana:

- Hoʻohui kemika: hiki ke hoʻohana ʻia ka 2-methylthioethanol ma ke ʻano he waena i ka synthesis organik.

- Detergent: Hiki ke hoʻohana ʻia ma ke ʻano he surfactant a me ka mea holoi i ka hoʻomākaukau ʻana i nā mea holoi.

- Hoʻopaʻa ahi ʻona waiʻona: hiki ke hoʻohana ʻia ka 2-methylthioethanol ma ke ʻano he mea pale ahi ʻona.

 

Hanana:

Hiki ke hoʻomākaukau ʻia ka 2-Methylthioethanol e:

- Hoʻokumu ʻia ʻo Thioethanol e ka hopena me ka methyl chloride.

- Hoʻokumu ʻia ka Ethiohydrazine e ka hopena me ka ethanol.

 

ʻIke palekana:

- 2-Methylthioethanol he ʻala ʻala a hiki ke hoʻopōʻino ka maka a me ka ʻili ke hoʻopā ʻia.

- Ke inhaled, hiki ke hoʻoulu i ka hanu a me ka ʻeha o ka umauma.

- ʻO ka ʻai ʻana a i ʻole ka ʻai ʻana i nā mea nui e hiki ke hoʻomake i ka maʻi ʻōpū.

- E hoʻohana i nā mea pale pilikino kūpono e like me nā mīkina lima a me nā makaaniani palekana ke hoʻohana.

- I ka hana ʻana, e haʻalele i nā lapalapa ākea a me nā wahi wela kiʻekiʻe e pale aku i ka hoʻoulu ʻana.
