Hoʻolauna

ʻO Dimethiomethane (ʻike pū ʻia ʻo methyl sulfide) he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka dimethylthiomethane:

 

ʻAno maikaʻi:

- Ke ʻano: wai kala ʻole

- Aala: He ʻala ikaika o ka hydrogen sulfide

- Solubility: Hiki ke hoʻoheheʻe ʻia e like me ka ethanol a me ka ether

 

E hoʻohana:

- Ma ke ʻano he mea hoʻoheheʻe: ʻO Dimethiomethane kahi mea hoʻoheheʻe koʻikoʻi koʻikoʻi i hiki ke hoʻohana ʻia e hoʻoheheʻe a hoʻomaʻemaʻe i nā pūhui organik.

- Chemical synthesis: Hoʻohana pinepine ia e like me ka reagent a me ka waena i ka synthesis organik, a komo i kekahi alkylation, oxidation, sulfidation a me nā hopena ʻē aʻe.

- Nā mea polimer: Hiki ke hoʻohana ʻia ka Dimethylthiomethane no ka hoʻopili ʻana a me ka hoʻololi ʻana o nā polymers.

 

Hanana:

- Hiki ke loaʻa ka dimethylthiomethane ma ka hana ʻana i ka methyl mercaptan me ka dimethyl mercaptan. I ka hopena, hoʻohana mau ʻia ka sodium iodide a i ʻole ka sodium bromide ma ke ʻano he catalyst.

 

ʻIke palekana:

- He ʻala ʻala ʻo Dimethylthiomethane a he mea hoʻonāukiuki hoʻi i ka maka, ka ʻili a me ka ʻōpū hanu. Pono e hoʻohana ʻia nā mīkina lima pale, nā aniani palekana a me ka pale hanu i ka wā e hoʻohana ai.

- I ka mālama ʻana a me ka mālama ʻana, pono e pale ʻia ka hoʻopili ʻana me nā mea oxidizing ikaika a me nā waikawa i mea e pale ai i nā hopena kemika weliweli.

- Ke puhi ʻia, hoʻopuka ka dimethylthiomethane i nā kinoea ʻawaʻawa (e laʻa me ka sulfur dioxide) a pono e hoʻohana ʻia i loko o kahi kaiapuni maikaʻi.

- I ka lawelawe ʻana a me ka hoʻolei ʻana i ka ʻōpala, e ʻoluʻolu e hahai i nā lula a me nā lula pili.
