Diethylaminosulfur Trifluoride (DAST, CAS 38078-09-0) – Wopanga ndi Wogulitsa Wamkulu ku China

Chiyambi

Diethylaminosulfur Trifluoride (DAST, CAS No. 38078-09-0) ndi mankhwala apadera kwambiri ophera fluorinating omwe amagwiritsidwa ntchito kwambiri mu mankhwala, mankhwala a agrochemicals, ndi organic synthesis. Monga opanga ndi ogulitsa ambiri a DAST ku China, timapereka DAST yoyera kwambiri ndi kuwongolera khalidwe, kuonetsetsa kuti ikugwira ntchito bwino kwambiri pamafakitale ndi kafukufuku.

Zinthu Zamalonda

• Fomula Yamankhwala: (C₂H₅)₂NSF₃

• Nambala ya CAS: 38078-09-0

• Chiyero: ≥98% (HPLC)

• Maonekedwe: Madzi opanda mtundu mpaka achikasu otumbululuka

• Malo Osungirako: Imafunika -20--2°C mufirijikupewa kuwonongeka

• Kukhazikika: Yosakhudzidwa ndi chinyezi; iyenera kusamalidwa ndi mpweya wosagwira ntchito (N₂/Ar)

Kugwiritsa ntchito kwa DAST

DAST ndi reagent yosinthasintha yokhala ndi maudindo ofunikira mu:

1. Mankhwala: Kutulutsa kwa mankhwala ophatikizana (monga ma steroids, mankhwala oletsa mavairasi).

2. Mankhwala a zaulimiKupanga mankhwala ophera tizilombo okhala ndi fluorine ndi mankhwala ophera tizilombo.

3. Kupanga Zachilengedwe: Kusankha fluorination ya alcohols, carbonyls, ndi heterocycles.

4. Sayansi ya Zipangizo: Kupanga ma fluoropolymers ndi ma crystals amadzimadzi.

Chifukwa Chiyani Sankhani DAST Yathu?

1. Ubwino ndi Chiyero Chosayerekezeka

• DAST yathu imayesedwa mwamphamvu ndi HPLC/GC-MS kuti iwonetsetse kuti ndi yoyera ≥98%, kuchepetsa zotsatira zoyipa.

• Kugwirizana kwa gulu lililonse kuti ntchito igwire bwino ntchito.

2. Mphamvu Yopangira Zapamwamba

• Malo opangira DAST akuluakulu ku China okhala ndi njira zovomerezeka za ISO 9001.

• Kutulutsa kwapachaka kwa matani opitilira 50, zomwe zimakwaniritsa kufunikira kwapadziko lonse lapansi.

3. Kusamalira ndi Kuyika Zinthu Mwapadera

• Kusungira: Kutumizidwa m'zidebe zotsekedwa, zogwirizana ndi unyolo wozizira.

• Kupaka: Mabotolo agalasi a Amber kapena ng'oma zachitsulo chosapanga dzimbiri pansi pa nayitrogeni.

4. Thandizo laukadaulo & Kusintha

• Mayankho opangidwa mwaluso (monga, maoda ambiri, ma formula osinthidwa).

• Zolemba za SDS, COA, ndi malamulo zaperekedwa.

Malangizo a Chitetezo ndi Mayendedwe

• Kusungirako: Kuyenera kusungidwa pa -20°C; kupewa kukhudzana ndi chinyezi/mpweya.

• Mayendedwe: Ogawidwa ngati zinthu zoopsa (UN 3286). Amafunika:

  • Zinthu zonyamula katundu wozizira (ayezi wouma kapena magalimoto oziziritsa).

  • Malo osungira mpweya wopanda mphamvu (N₂) m'mabokosi.

  • Kutsatira malamulo a IATA/ADR okhudza katundu wa pandege/pansi.

Mapeto

Monga opanga otsogola aku China a Diethylaminosulfur Trifluoride (DAST, CAS 38078-09-0), timaphatikiza kupanga kwakukulu, kuyera kwapadera, komanso zinthu zozizira kwambiri kuti titumikire makasitomala apadziko lonse lapansi. Kaya ndi kafukufuku wa zamankhwala kapena fluorination yamafakitale, DAST yathu imapereka kudalirika kosayerekezeka.
