Methanesulfonyl chloride/CAS：124-63-0

ʻO ka Methanesulfonyl chloride kahi hui i loaʻa nā hui hana sulfonyl chloride, i hoʻohana pinepine ʻia i ka synthesis o nā esters methylsulfonic acid. ʻO ka Methyl sulfonyl chloride kahi kemika ʻawahia loa, hygroscopic, corrosive, a me ka haehae. Pono e mālama ʻia kēia hui ma kahi maloʻo, ʻoi aku ka maikaʻi ma kahi mea maloʻo. I ka hana ʻoihana, hiki iā ia ke hana pololei i ka hopena radical manuahi ma waena o ka methane a me ka thionyl chloride.

Hoʻohana

Hiki ke hoʻohana ʻia ka Methanesulfonyl chloride ma ke ʻano he reagent analytical; Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻoulu no nā hopena esterification a me polymerization; Hiki ke hoʻohana ʻia ma ke ʻano he mea maka no ka hana ʻana o ka methanesulfonic acid; Hiki ke hoʻohana nui ʻia ma ke ʻano he mea maka synthetic no nā lāʻau lapaʻau a me nā pesticides; Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻopaʻa no ka wai sulfur dioxide, kahi mea chlorinating no nā dyes anthraquinone a me carbazole, kahi mea hoʻomaloʻo wikiwiki no ka hoʻomaloʻo ʻana i nā ʻīnika aila a me nā uhi, kahi mea hoʻomaikaʻi dyeing no ka polyester, kahi mea hoʻoponopono kala no nā kiʻi kala, kahi mea hoʻohuihui no xylene, naphthalene a me formaldehyde, a me kahi mea kōkua dyeing no ka hulu hipa.

ʻO ka hoʻohana nui ʻana o ka methylsulfonyl chloride ka hoʻomākaukau ʻana i nā methylsulfonyl esters mai nā waiʻona, kahi e pono ai ke komo ʻana o nā kumu non nucleophilic i ka wā o ke kaʻina hana. Hiki ke hoʻohana ʻia nā methyl sulfonate esters ma ke ʻano he waena i nā hana hoʻololi nucleophilic, nā hana hoʻopau, nā hana hoʻemi, a me nā hana hoʻonohonoho hou. Ke mālama ʻia me ka waikawa Lewis a me ka oxime, hiki i ka methanesulfonate ke hana i ka hoʻonohonoho hou ʻana o Beckmann.

Hiki ke hoʻohana ʻia nā esters methanesulfonic acid i kekahi manawa ma ke ʻano he mau hui pale no nā waiʻona, ka mea paʻa ma lalo o nā kūlana acidic a hiki ke hoʻohemo ʻia i ka waiʻona e ka sodium mercuric acid.

Hiki ke hoʻohana ʻia nā esters methanesulfonic acid i kekahi manawa ma ke ʻano he mau hui pale no nā waiʻona, ka mea paʻa ma lalo o nā kūlana acidic a hiki ke hoʻohemo ʻia i ka waiʻona e ka sodium mercuric acid.

Hiki i ka Methyl sulfonyl chloride ke hana me nā amines e hana i ka methyl sulfonamide. ʻAʻole e like me nā methylsulfonyl esters, ʻo ka methylsulfonylamide kahi hui hana i kūpaʻa loa ma lalo o nā kūlana acidic a me alkaline. Inā hoʻohana ʻia ma ke ʻano he hui pale e pale i ka hui amino, hiki ke hoʻohana ʻia ka lithium aluminum tetrahydroxide a i ʻole ka hopena hoʻemi metala i hoʻoheheʻe ʻia no ka deprotection.

I ke alo o ke keleawe chloride, hiki i ka methylsulfonyl chloride ke hoʻohui me nā alkynes e hana i nā pūhui β-chlorosulfonyl.

ʻŌpala a me ka Hoʻouna ʻana

250KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
Hiki ke hāʻawi ʻia ma ke kai a me ka lewa

Mālama a me ka mālama ʻana

Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
