Hoʻolauna

ʻO 2-Methyl-3-tetrahydrofuran mercaptan, i ʻike maʻamau ʻia ʻo MTST a i ʻole MTSH, loaʻa kēia mau waiwai:

ʻAno: ʻAʻole waihoʻoluʻu i ka wai melemele māmā.

ʻAla: He ʻono kūikawā ko ka hydrogen sulfide.

Density: approx. 1.0 g/cm³.

 

ʻO kāna mau hoʻohana nui penei:

ʻO ka mea hoʻomākaukau wai wai Ionic: Hiki ke hoʻohana ʻia ka MTST ma ke ʻano he solvent a me ka mea hoʻohui no ka hoʻomākaukau ʻana i nā wai ionic.

Hoʻohana ʻenehana: Hoʻohana mau ʻia ʻo MTST ma ke ʻano he mea hoʻohaʻahaʻa a me ka chelating agent i nā kaʻina hana e like me ka hoʻomaʻemaʻe metala, ka mālama ʻana i ka ʻili a me ka electroplating.

 

Ke ala hoʻomākaukau o MTST:

ʻO ke ʻano hoʻomākaukau maʻamau ka hana ʻana i ka methiophenol me nā reagents e like me ka magnesium methyl bromide a i ʻole copper methyl bromide i loko o ka tetrahydrofuran a i ʻole nā ​​​​mea hoʻoheheʻe kūpono e loaʻa ai ka huahana i koho ʻia.

 

ʻIke palekana no MTST:

He mea ʻawaʻawa loa: He mea hoʻonāukiuki ka MTST i ka ʻili, nā maka, a me ka ʻōnaehana hanu, a pono e hoʻohana i nā mea pale pono.

Hiki ke ahi: He wai wela ka MTST, a pono e pale ʻia nā kumu ahi a me nā wela kiʻekiʻe ke mālama ʻia a hoʻohana ʻia.

Hōʻalo i ka hoʻolaha lōʻihi: Hiki i ka loaʻa ʻana i ka MTST ke alakaʻi i ka make a me nā pilikia olakino ʻē aʻe, a pono e pale ʻia ka lōʻihi e like me ka hiki.

Ka mālama ʻana a me ka mālama ʻana: Pono e mālama ʻia ʻo MTST i loko o kahi pahu paʻa i ka ea, ma kahi mamao mai ka ʻā a me nā mea ʻona. Pono e hoʻolei ʻia nā wai ʻōpala a me nā pahu e like me nā kānāwai kūloko.

 

I ka hoʻohana ʻana a me ka lawelawe ʻana i ka MTST, pono e hoʻomaopopo a hoʻokō i nā kaʻina hana palekana kūpono a me nā lula.
